How to bind and reprogram the alarm key fob

The need to program a car alarm key fob may arise in different cases, be it a breakdown of the key fob itself, a lack of spare key fobs, or simply a measure to ensure the safety of the car (for example, when buying a used car). In any case, the car owner’s algorithm of actions is quite simple; this article will write a step-by-step guide to programming the most common starline key fobs. Programming the Starline key fob is quite simple, but it requires the car owner’s attentiveness and knowledge of some nuances.

Why is it necessary to reprogram the alarm?

The problem looks like this: the car owner approaches the car, presses a button on the key fob, and his car responds with deathly silence. There is a failure in the alarm system, which can occur for quite trivial reasons:

pressing several buttons on the key fob in random order. This is usually the sin of novice car enthusiasts who have not yet fully gotten used to the new alarm system;
The alarm system must be reprogrammed after purchasing the car second-hand. Of course, the seller will give the car enthusiast a couple of key fobs. However, most popular alarm systems have three (or four) such key fobs. So the only way to prevent potential theft is to reprogram the device.

Reprogramming the alarm key fob is necessary either in case of its incorrect operation, or in order to prevent car theft.

Damage to the car security system

If all the methods described above did not help you and your car still does not see a working remote key, then most likely the problem is hidden in the security system itself. Perhaps the alarm antenna itself is damaged in your car or the electronic receiving radio unit has failed. In this case, you need to contact electronic alarm specialists or an official technical dealership.

It is also necessary to remember that if your car does not see the remote key fob even after replacing its battery, then it is quite possible that the car key is faulty and requires repair. In this case, repairing it can be very expensive. So remember, friends, it’s better to order a new key from the dealer and not suffer.

It is also worth noting here that key fobs for used cars are widely available on the market these days. Compared to new keys, these used key fobs are very cheap. But you must remember that in this case it is unlikely that you will be able to independently register the key in the security system of your vehicle.

So the possible and imaginary savings of buying a used someone else’s key fob may ultimately result in unnecessary costs for you. Trust us, friends, it will be easier and more profitable to buy a new key fob. Success and good luck friends!

Is it possible to replace the old key fob with a new one?

The short answer is yes, you can change the remote control, but it’s not easy.

Previously, alarm systems were based on a permanent, static code that was easily picked up by attackers. Modern systems use dynamic code, and they work on a dialog principle, which looks like this:

after pressing the button from the key fob, the ID number is sent to the base alarm unit;
this number is checked by a system that “knows” the pattern on the basis of which it was generated;
if the check is successful, the base unit generates its own response number, which it sends to the key fob, after which the car owner gets access to the main alarm unit and can turn it off.

From all of the above, it becomes clear that after purchasing a new key fob, you will have to “register” it in the existing alarm system, i.e., make sure that the system begins to consider the new device “its own.” How to do this depends on the alarm model. In most cases, when replacing a key fob, it is necessary to completely reflash the software in the base unit, and this can only be done by a qualified specialist.

It’s not difficult to purchase a new key fob, but only a specialist can “link” it to an existing car alarm.

How to choose?

If the alarm remote control fails or is lost, the question arises of choosing a new one. But you should know that there are no options to choose from. A specific key fob provided by the manufacturer can work with each specific alarm. The name of the model can be found in the instruction manual or on the manufacturer’s website. If your alarm model is outdated and a new key fob cannot be purchased, you can find a used, working key fob. If you couldn’t find a used key fob, all that remains is to completely replace the alarm with another one.

However, large manufacturers such as StarLine have model lines of alarm systems that are similar in design, equipped with the same key fob, which can be re-flashed for a specific model.

How many remote controls can you register?

After purchasing a vehicle, you must install a new alarm system. In this case, the key fob will only need to be reprogrammed in the event of a divorce or any family disagreement.

If you buy a used car that already has a security system installed, the former owner can hide one of the remote controls and use it for illegal activities. In such a situation, the buyer must remember that up to 4 key fobs can be programmed onto one system. This number of remote controls is standard for each model of the security system, except for Scer Khan Magicar 5, and cannot be changed at the request of the car owner.

It is difficult to link a new alarm key fob to a third-party system. Because of this, you should install it on identical models and only after deleting all previously associated remote controls from memory. Otherwise, various difficulties may arise that will lead to malfunctions of the security system.

Reprogramming an alarm key fob is a simple task that anyone can do. To do this, you need to follow the instructions exactly and try to avoid mistakes.

Reprogramming devices from popular manufacturers

Before you start studying the issue of flashing the key fob, you should talk about one important general detail: the Valet button (aka Overread).

Each popular manufacturer offers users of their systems detailed instructions with instructions for reprogramming “unstuck” key fobs. But in any instruction it all starts with finding and disabling the above button. If the car is new (Western-made), then finding the button may not be easy. Here's where to look for it first:

in the fuse box in the passenger compartment (or behind this box);
under a small panel in the interior that says Fuse;
under the steering column (or under the panels inside it);
on one of the side walls of the glove compartment;
under all removable plastic covers on the dashboard;

If the search does not lead to anything, then there are two options left:

or the Valet button is located on the control unit of the system itself, and therefore only a specialist can get to it;
or in this system the Valet button is not provided at all, and its functions are assigned to the ignition switch.

Most car alarm key fobs from Western manufacturers have a Valet button

Replacing and linking the Sheriff system key fob

The interval between device reprogramming operations should be no more than 5 seconds. Therefore, before you start work, you should select instructions for your car alarm.

If this time is exceeded, the setup mode in the system will automatically turn off. Then everything will have to be done again. The same thing will happen if the ignition is turned off during programming. The successful completion of the reprogramming process in Sheriff systems is indicated by 2 signals: 1 short and 1 long.

If you need to flash a Sheriff brand keychain, don’t worry: you’ll spend 10–15 minutes on this task. A specialist video blog or detailed instructions from the car alarm manufacturer can teach you this procedure. In any case, the sequence of actions will be as follows:

the alarm is turned off, after which the ignition key is turned;
The Valet button is pressed three times. After this, a single signal should sound, confirming the readiness of the control unit to reprogram the key fob;
The Valet button is pressed again 3 times, after which 3 short beeps will sound, then 1 long beep;
button “1” is pressed and held until a long signal sounds, indicating that you need to enter a secret code;
a new code is entered using the Valet button;
the ignition is turned off and on again, after which the first digit of the secret code is entered using the Valet button;
the second digit is entered in the same way;
Now the Valet button is pressed 3 times, the alarm switches to the setting mode, after which 4 short and 1 long beeps will sound;
button “1” is pressed. It is held until a short signal appears, confirming the successful entry of the code into the system;
All of the above operations are repeated in turn with other key fobs that need to be linked.

How to program a Tomahawk key fob

“Pairing” a new key fob with an already installed Tomahawk car alarm is a little more difficult. To do this, you must follow the following sequence of actions:

the ignition key is turned (the engine does not start);
the Valet button is pressed and held until 4 beeps sound, indicating that you can begin programming the system;
The trunk open button is pressed simultaneously with the key fob sound button. The buttons are held until one short beep appears. The system is ready to write code;
The ignition is turned off, then the Valet button is pressed seven times;
after this the ignition turns on. Seven short beeps sound, confirming entry into the key fob programming unit;
The code numbers are set by pressing the “1” button;
After this, the ignition is turned off and the parking lights will blink 5 times, confirming exit from the service mode.

The Tomahawk car alarm key fob can only be reprogrammed by someone who has carefully studied the relevant instructions

How to connect the remote control to the SCHER-KHAN system

This system allows you to bind a key fob in two ways: using a PIN code and without it. The binding sequence without code is:

The ignition key is turned three times from the OFF position to the ON position. This should take no more than four seconds. If everything is done correctly, the flickering of the side lights will confirm that the programming block has been entered;
Next, the button on the key fob is pressed, and it must be pressed no later than three seconds later. The lights will blink again;
if there is a need to attach a couple more key fobs, the sequence of actions is similar, only after binding the second key fob, the dimensions blink 2 times, after the third - 3 times.

And here is the binding sequence with a PIN code:

first, all the steps listed above are performed;
after this, the ignition key is turned again, and the number of turns must correspond to the first digit of the PIN code. These actions must be completed within four seconds. The side lights will blink once, after which the second digit of the code is entered in the same way;
After entering the code, the button on the key fob is pressed, and this must be done no later than five seconds. The lights will blink 1 time to confirm that pairing is complete.

Reprogramming the key fob is quite simple. To do this, you only need a few button presses performed in a certain sequence. However, before starting work, it is recommended to study the instructions for the system in detail in order to understand what exactly you are doing. In addition, we should not forget about time: if the key fob is not touched for 5–10 seconds, it will simply exit the service mode.

Signaling sensors and alarm devices

Having locked the car and put it in security mode, the alarm control unit cannot independently track the various methods of hacking attempts. For this purpose, the system is equipped with a number of sensors. From the initial use of simple shock and door opening sensors, modern car alarms, as they developed, came to the use of several more types of sensors.

Door sensor

The main place for a car thief to enter a car is the car door. The door opening sensor was the first of the sensors used in car alarms. Most security systems are connected to the car's standard power supply using door lock limit switches or lighting microswitches. The same principle is used to trigger sensors that are installed on the hood, trunk lid or fifth door locks of hatchbacks and station wagons.

Shock sensors

The shock sensor is designed to prevent theft of wheels, exterior mirrors, attempts to break windows or mechanically break open a door. Various shock sensor designs use:

closure of electrical contacts, triggered by shocks to the body, chassis, hood, or wheel rims of the vehicle;
metal balls that roll when the car is hit or starts moving;
piezo plates;
counters of strength and number of alarm impulses.

Shock sensor

The complexity of shock sensors is due to the fact that this sensor is the main cause of false alarms in car alarms. The system, configured to be excessively sensitive, reacts to strong sound waves (thunder, noise from the engine of a passing truck), touching the body by yard animals, and falling snow.

Sensors for car windows have become varieties of the shock sensor - a pressure sensor on the glass and an air pressure meter. The security benefits of these sensors, which operate on the basis of a microphone (reacts to the sound of breaking glass) or on the barometer principle, are questionable. A thief or hooligan who decides to break glass is determined to act quickly and is ready to set off the alarm.

Volume sensor

The sensor, which records changes in the volume of the cabin, is built on constant scanning of the internal space with ultrasonic or microwave devices consisting of a transmitter and receiver. A number of experts consider such sensors to be useless. Manufacturers of car alarms do not comment on the difficult-to-explain point - how an attacker can get into the car, bypassing numerous other types of sensors. The grabber code, which disables the control unit, automatically turns off the signals from the volume sensors. Another disadvantage of most sensors of this type is false alarms if you leave bulky items in the cabin.

Tilt sensor

One of the most useful sensors, designed to prevent wheel theft or theft using a tow truck or truck crane. These actions by attackers require a relatively long time and are difficult to carry out when alarms are turned on. A reliable sensor design is considered to be a cylinder partially filled with mercury, which, when tilted, closes two electrical contacts connected to the car alarm control unit.

Tilt sensor circuit

Expensive alarm systems are equipped with several tilt sensors that operate in horizontal and vertical positions. Such a system responds to all ways of moving the machine. Correctly setting the sensors allows the alarm not to react to the natural movements of the car (swaying from strong winds, loss of pressure in one of the tires).

Motion Detector

High-end alarms use a motion detector consisting of a radar transmitter and receiver. An ultrasonic sensor is a type of such sensor. The device is capable of tracking suspicious movements of strangers near the car at a distance of two to five meters. Without turning on alarm signals up to a certain distance, the motion detector sends a signal to the remote control of the car owner, making it possible to call the police or scare away intruders.

Alarm devices

At the command of the sensors, the control unit of most alarm systems turns on sound and light signals that should scare away intruders. Light signaling uses headlights, flashing brake lights and turn signals, to which a special relay gives an unnatural rhythm.

To sound a sound signal in a hard-to-reach place under the hood, a powerful siren is installed. Self-powered sirens (with their own batteries) that operate when the car battery is disconnected are more effective. Loudspeakers that use various sound modulations and voice announcements can be classified as devices that make signaling more complex (and more expensive). The originality of the sound signal does not in any way affect its basic functions.

The need for reprogramming

There are various reasons when key fob programming is required. For example, when a user bought a new car with an already installed alarm system. In this case , it is better to reprogram the key fob so that unauthorized persons cannot disable the security.

Of course, you can do without flashing it, but if you buy an expensive car, such a procedure will not be superfluous. This procedure is also a solution if the owner loses the alarm key fob. The question of how to program a key fob also becomes relevant in the event of software failures. For example, when the device issues commands incorrectly.

In this video you will learn how to reflash the key fob:

The price for such a service depends on the complexity of the system. The average cost of reprogramming is 500 rubles. However, such work is simple, and, following the instructions, the user can do it himself.

Where and how to buy

You should not order a keychain on cheap Chinese sites. Firstly, there is a high probability that during its transportation the somehow assembled microcircuit will be damaged and the device will become inoperative. Secondly, there are no guarantees that the key fob will last at least a month and will correctly reflect information (not to mention responding at a distance).

If you want to get a high-quality keychain, our online store will offer competitive prices for devices and qualified assistance in choosing.

Preparation for the procedure

For those who are wondering how to reprogram a key fob, it is important to remember that preparation for such a procedure is necessary. To do this you need to follow these steps:

If you lose your key fob, you need to purchase a new device only of the model that was included with the installed alarm system.
If several radio transmitters are used to control the system, they must be reprogrammed at the same time so that they can be assigned to the new control unit.

Many suppliers include instructions in the kit. In this case, the user may have difficulties when there are no tabs with a translation of the instructions into Russian or they are written with errors (if the device was manufactured in Korea).

The motorist must first read the attached instructions. This document should show the design of the remote control. If there is no manual, the user should follow the generally accepted instructions.

Inspect all wires. Check the buttons, controllers, and indicator lights for short circuits.
If faulty parts are found, replace them with new ones.
Build the pager and test it in action.

Core Technology

The key fob reprogramming technology is simple. To do this you need to do the following:

By installing the key in the lock, the user must activate the ignition. There is no need to start the power unit.
Next, you need to simultaneously press with one hand the button with the loudspeaker and the button with the image of the luggage compartment. With your second hand, press the “service mode” button.
When the speaker beeps 5 times, you can release the pressed button.

Having correctly completed the proposed actions, the motorist must again press the button with the image of a loudspeaker and the button that opens the luggage compartment. As a result, the turn lights should flash several times.

It often happens that as a result of these actions the key fob is still not programmed. In this case, you can repeat the reprogramming along with recording the key fob. Another way is to reprogram the key fob without a code . To do this you need to do the following:

Within a few seconds, you need to connect and turn off the ignition system 3 times by turning the key.
If the motorist has done everything correctly, he will see a single flash.
After the flash is fired, the owner will have 4 seconds to press the communicator registered in the memory.
After recording on the first electronic remote control, the user can press a key on another key fob.
Information from the third key fob must be entered into memory in the same way. When recording the last remote control, information from the first device will be deleted automatically.

After the last remote control has been reprogrammed, you need to wait a few seconds. This is necessary to exit the recording.

How to repair car alarms: replacing quartz and other methods

It would seem that it would be easier to just take and replace the battery in the alarm key fob. The owner himself can perform this action without errors. Only now, after the replacement, the connection between the key fobs and the signaling is lost for some reason.

In reality, a loss of synchronization occurs, and the consequences of this “loss” can be corrected according to the text of the manual supplied by the manufacturer.

Here we consider what actions should not be allowed when repairing car alarms, as well as immobilizers and key fobs.

Key fob repair tips

A feedback key fob, or so-called pager, contains several elements in its design. The display is connected to the printed circuit board via a cable. But soldering this part (loop cable) is difficult in practice. This is precisely why the replacement operation has an increased cost.

Signaling pager circuit board

However, you can perform this replacement yourself. Which is proven in the video.

After disassembling and opening the plastic case, you will notice an important part covered with a metal shell. The cylinder is a watch quartz, and you need something similar.

Radio module printed circuit board

Let's say the pager display shows that there is no connection. In this case, repair of the alarm key fob is carried out as follows:

Solder the connection point with the antenna, perform assembly and testing;
If the defect remains, replace the main quartz.

In general, repairing car alarm key fobs does not involve searching for defects using special equipment. They are more often guided by logic, changing “suspicious” components and parts. They also strive to eliminate mechanical defects: they replace button modules and restore contacts. The main thing is to remove all power elements before soldering. And wait 20 seconds.

Any button can be replaced

Repairing a key fob with your own hands is a painstaking and difficult job. Having removed any battery, it will be necessary to restore synchronization. But equipment working with dialog code does not lose synchronization.

We repair the standard immobilizer ourselves

Any modern car has a module installed that automatically blocks the engine. Such modules are called “immobilizers”, and their malfunctions are characterized as follows:

You cannot start the starter even with your own (standard) keys;
Commands from the remote control (key) buttons are not perceived in any way.

Sometimes the problem lies in the electronics of the remote control. But hardly anyone will undertake to repair it.

Remote key for LADA cars

Here we discuss how to repair the immobilizer, more precisely, the antenna and the main unit. The block itself, at least, can be disassembled by hand without using special equipment.

Case Study (GF-626)

The standard equipment of the MAZDA GF-626 is an immobilizer, in which the main communication frequency is set by a ceramic resonator. The specified part looks like this.

Standard unit MAZDA GF-626

Over time, the parameters of parts change. Therefore, repairing the immobilizer will consist of the following: unsolder the “bad” resonator, install a new quartz in its place. The frequency of the quartz resonator can be selected experimentally (here the numbers 2.4576 are indicated on the case).

Main unit after repair

Let us make a digression regarding the choice of resonators. If you buy a replacement quartz with the corresponding numbers, you may not always get a good result. The reason is the following:

Low thermal stability;
Frequency jitter.

In general, a new part is selected as one of several. What you need to know when repairing an immobilizer, key fob, and even an alarm system. Who said it would be easy?

Inductive antenna repair

The immobilizer reads data from the key, establishing radio communication with it. The following is typical for standard automotive systems: an inductive antenna is wound around the ignition switch. Let’s say you can’t start the starter even with your own keys, which are programmed into the memory of the main unit. Then the immobilizer repair begins with checking the antenna, completely disconnecting it from the connector.

Antenna removed from the ignition switch

The appearance of the antenna module is shown in the figure above. It may turn out that the resistance between the black and white wires is infinity (open).

The connector was connected to the immobilizer

No one can wind such a reel by hand. But you can do the following:

A soldering iron without solder is placed between the turns, and each turn is passed until the ohmmeter shows 5-10 Ohms;
The gap is eliminated, even with the appearance of short-circuited turns.

Setting up the Sherkhan alarm

Before working with the Sherkhan alarm system, you need to disarm the system. Next you need to complete the following steps:

First, you need to press the Vallet button so that the alarm lights flash.
Next, you should click Vallet again. As a result, the LED will start blinking.
After this, you need to press Vallet as many times as there are numbers in the PIN code. This step must be repeated for all digits of the PIN code.
6 seconds after the last digit of the code has been entered, the alarm will flash. Thus, the system will confirm its readiness to enter the code.
Within 4 seconds, you need to briefly press the fourth button on the first key fob 2 times. If the recording is successful, the alarm will automatically flash.
After this, you can enter the codes of the remaining key fobs. If the code is entered successfully, the alarm will flash.

To exit reprogramming mode, you do not need to take any action for 5 seconds after the last code was written. As a result, the alarm will flash and the system will exit reprogramming mode.

In what case may it be necessary to reprogram the alarm key fob?

None of us are immune from loss. This also applies to the car alarm key fob, which is also called an interactive pager. Most often, it is attached to a key ring, so the risk of forgetting it somewhere is reduced. However, if this does happen, you will have to think about purchasing a new device.

Using this remote control you can remotely control your car alarm.

Don't be alarmed; if you lose your key fob, you don't have to change the entire alarm system. The only exceptions can be if the alarm is quite rare, recently released or, conversely, outdated. It happens that the desired model cannot be found either in your city or in online stores. In such a situation, it makes sense to contact a car service: they can suggest a solution to the problem and point you to the sellers of the system you need. If after this you were unable to purchase the required model of key fob, you will have to completely change the alarm system.

Please note that the new control panel must be selected not only in accordance with the brand of the security system, but also taking into account its type and model. Thus, the starline b6 keychain cannot be replaced with starline b6 dialog.

New car alarms are usually programmed by system installers. In this case, you have nothing to worry about. The required code will be installed on all key fobs and linked to the system. But if you buy a car on the secondary market with an already installed car alarm, it makes sense to take care of reprogramming the device.

The fact is that unscrupulous owners can give you an incomplete set of control panels, which means they can easily disable the security system and steal your car. Unfortunately, some scammers are already doing business this way. To avoid this problem, reset the code immediately after purchasing the machine.

Sometimes it happens that the key fob gets untied from the alarm for no reason. Many factors can cause such a failure. Sometimes this happens due to randomly pressing different buttons. If this happens to you, don't worry. In most cases, the problem is solved by reprogramming the key fob.

Typically the kit includes up to 4 alarm control panels. If you decide to reprogram them, do it in a row with all the key fobs.

Devices providing security functions

The main devices that provide protective functions and control the car alarm are the electronic control unit and the owner's key fob.

Alarm control unit

Device diagrams and electronic codes of the control unit are the most secret and protected part of the car alarm system by manufacturers. When installing an alarm system, it is recommended to camouflage the miniature control unit in an inconspicuous place in the cabin or engine compartment.

Despite the official approval in Russia of a single frequency for car alarms at 433.92 MHz, many accessory manufacturers produce systems operating at frequencies of 434.16, 371, 868 MHz. Car alarms for mobile communications are tuned to GSM frequencies (from 850 to 1900 MHz).

Information about operation on a single frequency or accurate data about the radio frequencies used makes the tasks of car thieves easier, so information from the Internet should not be trusted unconditionally.

An important secret part of the control unit was a device that encrypts electronic access codes. Having abandoned static (unchangeable) codes, almost all modern alarm systems have switched to the use of dynamic coding, in which the alarm control unit generates a new signal every time it is turned on.

Dialogue between the key fob and the alarm control unit

The next step to complicate the hacker's tasks was an interactive coding system. When there is radio contact between the remote control (owner's key fob) and the main control unit, each stage of friend-foe recognition and changes in alarm tasks is step-by-step encrypted with a separate dynamic code. The technical part of the control unit is a transmitting and receiving radio antenna, the design of which does not affect the security functions.

Remote control

The remote control of a modern car alarm contains a miniature radio signal transceiver from the main control unit and the second part of a dynamic coding generator in one housing. The main task of the remote control is to turn the alarm on and off inaccessible to others. The main improvements of this function are to reduce the sensing distance and make it more difficult to intercept the encoded signal.

Additional functions reflected on the key fob display can signal the activation of a specific sensor (shock, volume change, door opening) and the activation of the siren. Flashing characters on the remote control display are usually accompanied by a sound signal or vibration of the key fob.

How to reprogram the alarm key fob

There are a large number of models of protective systems. For each of them, a key fob is programmed, referring to the instruction manual. In all cases, the work should be done carefully and not overlook the slightest detail.

How to register Sheriff

The Sheriff security system is considered the most popular. You can find a large number of models on sale that are characterized by good reliability. For any type of device, it will be possible to register an alarm key fob in a minimum amount of time.

Step-by-step instructions for flashing:

The first thing they do is get into the car and lock it.
The ignition key is set to the first position.
Press the Valet button three times. As a result of these actions, the device will emit a long beep.
They repeat all the same steps, and the car alarm emits several short beeps, followed by 1 long beep.
Press the system activation key and hold it in this position until a long signal sounds.
After waiting a few more seconds, you can start pairing all the other remote controls. This is done in the same way as activating the first key fob.
At the next stage of the settings, a security code is set. To do this, turn the ignition key and wait for the engine to start.
Then turn off and turn on the ignition again.
After this, press Valet. The number of clicks must correspond to the first digit of the selected security code.
Set the second digit in the same way and turn off the ignition.
When the engine is turned on again, the device will notify the car owner that the code has been correctly set.
After this, you have 5 seconds to switch the ignition key to on mode.
If necessary, change the code by pressing Valet 5 times.
After a short and long beep on the control panel, click on the button with the image of a closed lock.
The alarm will emit a signal, after which 2 digits of the new code are entered one by one.
At the very end, turn on the ignition and wait for the device to react.
As soon as it makes 2 sounds, system programming is completed.

How to flash Tomahawk

Flashing a key fob for the popular Tomahawk security system is as easy as for Sheriff. This is explained by the presence of similar buttons on the control panel, only one of which will have a different name (Override instead of Valet).

Standard firmware method:

At the beginning of the process, turn the ignition key, but do not start the car engine.
Press and hold the Override key for 30 seconds. During this time, the device should emit 4 beeps, indicating the start of the key fob programming process.
After this, simultaneously press the volume control and the button that opens the trunk.
As soon as the car alarm beep sounds, the pairing of the remote control will be completed. When connecting each subsequent key fob, there will be 1 more such signals.

This programming method allows you to configure any Tomahawk model except the Z-5. For this security system, the procedure will be slightly different.

Step-by-step instruction:

The ignition key is set to the first mode.
Press the Override button 7 times.
After this, the key is switched to the second mode.
After completing these steps, you will hear 7 short beeps indicating that the settings mode has been activated.
At the same time press the button for setting and disarming the car (with the image of an open and closed lock).
Hold them until the system beeps, the number of which corresponds to the number of the key fob being connected.
Then turn on the ignition. In this case, the parking lights should flash 5 times.
After these steps, you need to wait 10 seconds until the security system exits the programming mode.

How to connect Scer Khan Magicar 5

The Scer Khan Magicar 5 car alarm is a reliable security system that prevents any attempts to steal a car. Its only drawback is the ability to connect only 3 control panels. If you want to connect key fob No. 4, you will have to erase any of the added ones.

When installing the alarm and flashing the key fob, you need to perform a few simple steps. Among them should be the following:

To set up the alarm key fob, turn the ignition key 3 times.
After this, turn it off and make sure that the side lights give a light signal.
On one of the remote controls, press the button with the image of a closed lock.

Types of keychains: brief overview and characteristics

Firstly, you need to take into account that modern cars are equipped with standard security systems. They come with control key fobs. The standard remote control is housed in a single housing with the ignition key. This key fob can look like a regular key with control buttons, or like a remote control with a flip key.

Secondly, all modern car alarms are equipped with two key fobs: the main one and the additional one. The main key fob allows you to work with all functions of the system. Additional - has a limited set of commands (open and close the car, turn on silent mode). An additional remote control (key fob) is designed to control the security system in case of loss or malfunction of the main key fob.

Important! The additional key fob is not intended for permanent use. You will not be able to use all the alarm features and receive information from the vehicle.

All car alarm key fobs are classified as follows:

By the number of buttons. Most key fobs have from one to five control buttons. Key fobs with 1-2 buttons can only control the opening and closing of doors. If the remote control has 3 or more buttons, then other buttons may be responsible for turning on silent mode, opening the trunk, or be programmable for various functions.

There are also buttonless key fobs. They are called tags. Tags are an additional protective system of the car and serve as an immobilizer. Those. The car engine will not start if this mark is not in the car.

According to the presence of the screen. The screen on the alarm panel is present if the system supports the feedback function. The screen is needed to display information coming from the unit in the car, for example: temperature inside the car, voltage in the on-board network, alarm messages. Some key fobs show the time and have an alarm. Key fobs without a screen are either optional or included with simple security systems without feedback.
Main or additional. The differences between the main and additional key fobs are described above.

You can make a key fob with a flip key for a non-standard alarm system . To do this, you need a special case into which the insides of the remote control and the immobilizer chip are installed. You also need to order a duplicate of the ignition key, the blade of which fits into this housing.

Firmware methods depending on the alarm model

After the service button has been found, the process of recording key fobs into the alarm memory should begin. Depending on the models, one firmware method should be used.

As soon as you enter the service mode, press and hold buttons 1 and 2 on the key fob simultaneously (for B6D, B9D, B61, B91, A61, A91, buttons 2 and 3), the key will be registered in the alarm unit.
When the key fob is successfully recorded, 1 beep will sound. If you need to bind a new key fob, then immediately after programming the first one, take the second key fob and press buttons 1 and 2 again. As soon as the key fob is registered, the alarm will notify you with a sound signal. If it was not possible to reprogram the key fob, the alarm unit will exit and switch from the service mode to the standard mode (the turn signals flash 5 times).

If you need to record an additional key fob, then immediately after recording the first one, start recording the second key fob, to do this, press and hold buttons 3 and 4. After recording the next key fob, the alarm will notify you with a signal, the number of signals depends on the order of the key fob for recording.
If the key fob has not been recorded, the alarm will exit the service mode (the turn signals flash 5 times).
After recording the required number of key fobs, turn off the ignition, thereby disabling the alarm from the recording mode (the turn signals blink 5 times).
