How to completely remove the alarm from a car: instructions for dismantling an old car alarm with your own hands and installing a new one, video on how to dismantle the alarm

Modern electronic car security systems are reliable and durable. However, the alarm may need to be removed. This can be done best by service station specialists. But this opportunity is not always available. Car owners are often confused by the high price of qualified service. This is due to the complexity and high labor intensity of such a procedure as replacing an alarm system.

If you wish, you can do this work yourself, following the instructions and guides on this topic.

Reasons for dismantling

For what reasons may it be necessary to remove the alarm:

Serious malfunctions were discovered related to the operation of the main alarm elements. For example, the control unit has failed, and the model of the “alarm” is too old. Therefore, it is not possible to buy a new module, and it is impossible to carry out repairs. The same goes for shock sensors.
The anti-theft installation began to interfere with the performance of the main systems and components of the car. This problem is more relevant for some modern vehicles equipped with many electronic systems.
The system does not respond to signals sent through the control panel. The key fob itself is working, but it is not possible to determine the cause of the malfunction.
There were some glitches in the work. All components of the car alarm are intact, but the siren goes off automatically for no reason.
The “alarm” has broken down, as a result of which it neither turns on nor turns off.

Safety precautions during dismantling

The basic safety rule when performing auto repair work is to de-energize the system. To do this you need:

Unscrew the nut of the clamping bolt on the negative terminal of the battery;

remove the terminal from the power supply pin;
take measures to prevent accidental short circuits at the battery terminals.

This precaution will prevent damage to the electrical circuit.

If the body needs to be lifted to remove equipment, measures must be taken to prevent it from falling off the jack. For this purpose, supports and wheel chocks are installed.

Basic principles of car alarm dismantling

In order for the Alligator, Starline or any other engine to start after dismantling the anti-theft system, it is necessary to take into account the following principles for disabling and removing the alarm:

The dismantling of the anti-theft system must be entrusted to a specialist or car enthusiast who has an understanding of the operation of the on-board network and understands the features of installing and disabling the “alarm”. Mistakes made can be costly for the car owner.
When removing, the driver must understand that depending on the model, the anti-theft system may behave differently. Some alarms block the power unit, as a result of which, after it is turned off, starting the engine will be impossible. Or a siren starts to sound, which cannot be turned off using the key fob. To fix the problem, manufacturers use different solutions. For example, the alarm system may come with a special key designed to disable the secret block. Or you can de-energize the car alarm using a special combination that is entered by the Valet service button.

Before performing the alarm dismantling procedure, we recommend that you study the installation manual in more detail.

The AvtoGSM channel showed how to replace one model of anti-theft installation with another.

What do you need to know before removing the alarm?

When removing an anti-theft system installed on a car, you must pay attention to the following principles and features:

Disabling the “alarm” of a Starline, Alligator or other car model should be carried out by specialists or car owners who understand the principle of operation of the electrical network and the removal of anti-theft systems. If you incorrectly disconnect the main module or elements of the car alarm, this can result in a short circuit and other malfunctions.
During the shutdown process, the alarm may lock the motor, resulting in the engine being unable to operate. If you disconnect the wires while the power is on, some Starline and Alligator models begin to sound a siren, which cannot be turned off with the key fob. The anti-theft system may include a special key that can be used to turn off the sound signals. You can also turn off the siren yourself using a personal password entered using the Valet service key.

Safety precautions during dismantling

To remove the old alarm from your car yourself, you need to consider the following safety rules:

Before performing the task, you must make sure that there is no power to the network. If the alarm is dismantled while there is voltage, the car owner may receive an electric shock, and in such a situation there is a possibility of electronic failure.
After the car owner completes dismantling, it is recommended to check the operation of the alarm elements to detect the causes of inoperability or failures. Diagnostics should be carried out in special clothing and using rubber gloves.

Step-by-step instruction

To completely remove the alarm from your car, you need to:

Turn off the voltage in the car's electrical network. To do this, open the hood, loosen the negative terminal on the battery with a wrench and disconnect it.
The next stage takes place inside the car. When performing this, you need to find the LED indicator located in the front of the car near the center console. A wire goes from the light bulb to the control unit. Find the module and disconnect the plug with contacts from it.
Disconnect the standard wires from the on-board power supply. If the anti-theft system is equipped with an immobilizer, at this stage it must be disabled. Loosen the fasteners securing the device and remove the IMMO.
The control module is connected to connectors for powering the lights of the turning lamps, clearance lights, door switches, trunk, as well as the power unit locking device. Each component is disconnected. If a complete replacement of the anti-theft system is required, then it is necessary to dismantle the electrical circuits connected to the components of the “signaling system”.
Sensitivity, tilt, motion and other controllers are disconnected and dismantled if the car is equipped with them. Depending on the car and model of the alarm, as well as the installation method, the location of the devices may be different. Typically installers place these sensors under the parking brake control handle.
If a motor blocking device is used, the contacts from the power unit must be removed carefully. The same applies to blockers of the starter device, fuel pump, etc.
When all components are disabled, the Valet service button is removed. The siren installed under the hood of the car is dismantled. After removing all the clamps, the old wires coming from the passenger compartment to the engine compartment are removed.
The battery is connected, the driver needs to try to start the engine. If the shutdown procedure is performed correctly, then there will be no problems with startup.

The From Theft channel demonstrated the procedure for dismantling an anti-theft installation using the example of a Toyota Rav4 car.

Is it possible to transfer an old alarm from one car to another?

If the dismantled alarm was in working order, and the work on its removal was carried out carefully, without damaging the elements, then it can be reinstalled on another car. Even if the electrical wiring has been damaged, it can be easily restored.

Moreover, you yourself can purchase a used car alarm to install in your car. This can save you a fair amount of money. However, you should carefully check the condition of the system elements. If you do not trust the seller, then you should refrain from purchasing. The fact is that until you install the system, you will not be able to assess its serviceability. And once again installing and removing the alarm takes a lot of time and effort.

Possible consequences and their solutions

Mistakes made during the dismantling process can lead to the following consequences:

Violation of the integrity of the wires used. Damaged electrical circuits must be replaced. For minor faults, only part of the chain section can be replaced. If an insulation failure occurs, the wire can be re-wrapped with electrical tape.
Errors can cause electrical equipment to malfunction. The method for fixing the problem may vary depending on the type of damage. Minor breakdowns are solved by repair, replacing damaged contacts, etc. If the problem is serious, the failed electrical appliance is completely replaced.
Incorrect dismantling will lead to damage to the decorative lining of the interior.
If you disable the engine locking device incorrectly, it will be difficult to start the power unit. It is necessary to correctly dismantle the component elements; if necessary, the removal procedure is repeated.
One of the most serious malfunctions that can occur during dismantling is the failure of the anti-theft system control unit. If it breaks, the alarm will not work. Some problems can be solved by flashing the module or resoldering damaged contacts.
Errors may affect battery performance. Rapid discharge and damage to the internal plates will cause the battery to not function correctly.

1. Collapsed battery plates

2. Damaged electrical circuits of the “signaling”

Possible consequences of deletion

After completing the work poorly, the following problems may arise:

Short circuits and blown fuses. Most likely this occurs either due to incorrect restoration of the wiring, or due to poor-quality insulation of the abandoned alarm wiring.

The engine does not start. Most often this happens if the system had an autorun function. Without restoring the standard wiring, but simply removing the elements responsible for autostart, the signal to start the engine will physically not be able to reach its destination. Some installers also use their own engine locking methods and these can be difficult to detect.

Malfunction of individual vehicle systems. Inoperability of the door lock drive, horn, and lighting equipment is most often caused by improper restoration of the wiring.

Installing a new alarm

The installation procedure for the anti-theft system is as follows:

Disconnect the machine's on-board power supply. Disconnect the terminals from the battery in the engine compartment, first loosening the fastenings on them.
Install the control module. The control unit performs one of the main functions in the operation of the alarm system; it receives, processes and sends signals to the remote control. If a criminal gains access to the device, he will be able to disable the alarm siren. Therefore, the control unit must be mounted in a hidden, hard-to-reach place. You can install it in the dashboard area; you will have to disassemble part of the center console.
Install limit switches on the hood, doors, and trunk of the car. To do this, the door trim is disassembled and the wiring from the devices to the control module is laid.
If the anti-theft system is equipped with an immobilizer, install this device. To connect, use the diagram that comes with the kit. Typically, the device is mounted in a section of the electrical circuit running from the ignition switch to the starter device.
Install and secure all sensors included in the kit. Their number may vary. The package must include a sensitivity and impact controller. More modern alarms allow you to connect tilt and motion sensors. For installation, use the diagram included with the system. The sensors must be securely fixed so that they do not go off without a reason.
Wires are laid from all components of the system to the control unit. Connect the wiring. Activate the battery and configure the alarm by linking both remote controls to it and adjusting the sensitivity of the sensors.

Price for withdrawal in the service

If it is necessary to dismantle the security system, a reasonable option would be to contact a specialized service center. However, you may be surprised that the price of such work will be close to the price of installing a new one and will be at least 2,000 rubles. The work will be more difficult and more expensive if:

alarm with feedback;
equipped with autostart;
there are additional engine locks;
there are GSM or satellite modules;
the system is combined with an immobilizer;
information from the door switches is taken not from the CAN bus, but through separate non-standard electrical wiring;
Additional sensors are installed (tilt, volume, motion).

For each of these points, you can safely add 500-1000 rubles to the price of the work. Especially if it will be necessary to search for and remove non-factory wiring.

Important! Unskilled garage repairmen may charge a small fee for this work. However, the quality of their work leaves much to be desired. They may not only not complete the job, but also damage the car.

How to turn off car alarms

The “barbaric” method of cutting through the wiring of your car with wire cutters, which previously could be used to unlock the alarm, is now unlikely to work. Since modern cars have long had multi-stage burglary protection. However, you can try.

Another method involves finding a relay that is responsible for powering and controlling the security system, but here there is also a high probability that the method will not work on a new car.

In order to analyze the combinations for disabling common types of anti-theft systems, each of them should be considered separately.

How to disable sheriff

One of the most popular brands is Sheriff. The sequence of actions that must be performed in order to disable the sheriff alarm:

First of all, you need to open the car using the key;
start the engine;
press the secret Valet button;
turn off the engine, then start it again;
Finally, click on Valet again.

As a result, the Sheriff model alarm should go into service mode. Then you can begin to find out the cause of the system damage without any obstacles.

How to disable pantera

Another common model of secret police that can be found in the Russian Federation. This brand works especially well in low temperature conditions. But in order to forcibly turn off the Panther alarm on a car in emergency situations, you should use the following methods:

Open the car with the key and hold down the Valet button for 15 seconds. As a result, a short signal will be heard, and the block sensor should light up.
Turn off the starter deactivation mode and turn off the security remotely using the key fob.
Turn off the alarm using the Valet button after activating the service mode, and dial an individual PIN code.

How to disable alligator

You can disable the anti-theft system of the Alligator D-810 in emergency mode or by pressing Valet. The second method is the most common and is implemented as follows:

The car interior is opened with a key;
turn on the engine;
15 seconds use Jack;
turn off the engine.

However, performing this manipulation will not disable the service mode. Cars in which the passive vehicle protection system is activated will immediately reactivate it 30 seconds after repeated manipulations.

But in this case, it is possible to switch the alarm into service mode using a PIN code that is set by the owner of the car. To do this, you can use any four-digit combinations from one to 99. The only restriction is on the use of “0”. In order to reset the alarm, the driver must:

unlock the car with the key;
start the engine;
turn it off and start it again;
use the Valet button several times in the next 15 seconds, depending on which digit of the code is the first;
turn off and turn on the engine again;
repeat the item using the button again, only now taking into account the second digit in the password;
turn off and start the engine again.

This sequence is performed according to the number of digits in the code. If everything is done correctly, the procedure will be successful. It is very important to enter the code correctly the first time, otherwise if it is entered incorrectly 3 times in a row, the alarm system may become unavailable for some time.

How to work with Alligator Lx-440 brand:

open the door with the key;
start the car;
click on Jack in the next 10 seconds;
turn off the engine.

To transfer the system to service mode, you must follow the sequence of actions as in the previous case. However, in this situation, the code can be a two-digit value consisting of numbers from one to 9. Here's what you need to do:

open the interior mechanically;
start the engine, turn it off and start it again;
hold the car for 10 seconds, pressing the Jack button several times in accordance with which number is the first;
turn off and start the engine;
repeat the point with the button, which must be pressed as many times as corresponds to the second digit;
turn off and start the engine again.

If the driver enters the wrong code three times, then, similar to the previous case, the system is blocked. Only now for 30 minutes.

If we talk about the “Alligator” as a whole, it will be difficult to deactivate it when the control relay is turned off, since the fuse in such a system is open. The same cannot be said about Starline, which has a closed fuse.

How to turn off the starline alarm

The most advanced model of our time is Starline A93. However, it can also be removed; this is done in this way:

unlock the door;
turn on the engine;
press the service button according to the first digit of the password;
turn off the engine;
repeat several times until all password digits have been used.

For the Starline 525 model, the following sequence of actions occurs:

unlock the door and leave it open;
start the engine;
keep the Jack button pressed for the next 6-second period;
after which the driver may notice an LED signal and an audible warning from the system, this all means switching to Valet mode;
turn off the engine.

In order to disable the Starline A6 car alarm, you need to use a password and resort to the following actions:

open a car dealership;
start the engine;
press the service button several times within 20 seconds according to the first number indicated in the password;
turn off and start the engine again;
then repeat the step by pressing the Valet button several times in accordance with the second digit of the password;
turn off the engine.

The step-by-step procedure for removing the security signal of the STARLINE TWAGE A8 model is presented as follows:

open the car;
start the engine;
press the service button for a 20-second period;
turn off the ignition.

If the system is working properly, its response to the driver’s actions will be 2 sound alerts and 2 flashes of the vehicle’s dimensions.

How to disable tomahawk alarm

Looking at the RL950LE model, you can understand that it is possible to disconnect the alarm as follows:

the driver unlocks the door;
starts the engine;
presses the service button 4 times in the next 20-second period;
turns off the engine.

If the Tomahawk model alarm is successfully cleared, the driver can hear 2 audible alerts and see 2 flashing lights.

How to turn off the Sherkhan alarm

The most popular model of the Sherkhan brand is SCHER-KHAN MAGICAR II. In order to clear an alarm of this type, you need to:

unlock the car door;
for 3 seconds, the car owner must switch the ignition circuit to the on state;
turn off the engine.

If everything is correct, the car will indicate this by turning off the security signal, the lights will blink first once, and then a couple more times after 6 seconds.

You can disable the Sherkhan MAGICAR IV alarm as follows:

the driver unlocks the car;
in a 4-second period, turns the ignition circuit to the on position 3 times;
then the engine turns off.

In this case, if the actions are correct, the car lights will blink first once, and after 5 seconds two more times.

You can reset the siren on SCHER-KHAN MAGICAR 6 using a password. It is set equal to 1111. To deactivate, the driver takes the following actions:

opens the car salon;
turns the ignition to the “on” position 3 times in a 4-second period;
turns off the engine;
again switches the ignition circuit several times depending on which digit is the first;
turns off the engine;
repeats the procedure until the remaining digits have been entered.

After completing the manipulations, the dimensions should respond with two blinks. If this does not happen, it means that a mistake was made and the car is not removed from the alarm system.

If the driver does not have time to complete everything within 20 seconds, and the Valet button cannot be found, then you need to give the alarm time to rest and start looking for the secret button at this time. After finding it, you need to lock the door and do everything from the very beginning. Then there may be enough time.

When setting a code, you should never forget its first two digits, because they are needed to set the password for the new key fob.

How to turn off the leopard alarm

To turn off the alarm on a VAZ 2107 with the brand LEOPARD LS 90/10 EC, you can use the deactivation method in emergency or coded mode. The application of the first method is as follows:
