One of the features of expensive cars is the presence of an engine start/stop button instead of the usual ignition key. AVTOVAZ does not yet provide the “Start the engine with a button” option, but any owner of a Lada car can modify the design with their own hands.
Below are two diagrams for connecting the start/stop button:
- Installation of a ready-made kit with a button, control unit and wires (price about $35), see the Aliexpress catalog;
- Self-production of one of the most popular circuits based on automotive relays (costs about $6).
In both cases, the scheme can be implemented on any Lada car (XRAY, Vesta, Largus, Granta, Kalina, Priora or Niva 4x4), including foreign cars. The button is installed in place of the ignition switch.
The ignition switch can be:
- put away;
- leave. Connect the start/stop button to the ignition switch connector (allows you to return to the key-start scheme within 10 minutes), and to prevent the steering wheel from being blocked, leave the key cut off and turned in it.
What are the pros and cons of installing it in a car?
What are the benefits of using a button?
- A light press is enough to start the engine.
- You no longer need to carry the ignition key with you.
- The button can be installed anywhere, including right at hand, which increases ease of use.
- A number of options are combined with car alarms, immobilizers and other security systems.
- You can lock the car by simply pressing a button on the door, without having to set it to the alarm - this saves time if you leave the car for a short time.
If you do not have basic electrical skills, it is better to seek services from a service station
Are there any disadvantages? Alas, yes.
- To start the car, you need to sit in it and press the brake pedal. Out of habit, many drivers forget about this.
- There may be difficulties when installing an alarm with heating. So, you will need at least two keychains - one of them must be given to the masters. They will disassemble it, take out the chip and install it in the car. Power will only be supplied at startup.
- Installing an alarm on a car with a button usually costs more.
There is an opinion that if the battery in the key fob runs out, the car will not be able to be started with the button, but this is not so. Just bring the product to the button and everything will work. If the battery runs out, you can open the car with the key.
Installation methods
Nobody significantly limits car owners from installing a button on their car to start the engine with a simple press.
Therefore, more and more often you can meet those who want to install a solution:
- for 140 Mercedes;
- Niva;
- Lada Granta;
- Hyundai Solaris;
- to Priora;
- Honda cars;
- Mitsubishi ACX;
- Mitsubishi Lancer;
- Audi 100 C4;
- Toyota Yaris;
- Kia Rio;
- and even VAZ 2114.
The main thing here is to decide whether you really need this button. If yes, then move on to choosing the system itself.
Modern manufacturers of universal buttons allow you to select a mechanism for any machine. Please note that there are various connection schemes. Each of them has its own characteristics.
DIY installation options
There are many product installation schemes, each with its own characteristics.
- Option with ignition key. In this case, you will need a key to start. Turning it turns on the ignition, and to start the engine you will need to press a button. There is an option without a key - it is simpler, you just need to press a button.
- “Short” and “long” press. In the first option, you need to press the button briefly - the starter will spin until the engine is activated. The second involves holding the button - the starter rotates only while it is pressed.
- Various options for turning on the ignition. The first option is to turn on the ignition when you press a button. The second is the ability to activate it only together with the starter.
This is what the installation instructions usually look like
Experienced car enthusiasts combine different options, getting interesting schemes. To install the Start-stop button, you do not need to be an experienced auto mechanic - just ordinary knowledge in the field of car operation is enough. But if you want to implement a complex circuit, with a timer, startup delay and other nuances, you will need serious effort and a large number of additional components.
How to install
Regardless of the option chosen, you first need to prepare the installation site. To do this, you must either remove the ignition switch or cut a separate hole on the dashboard. This can be done with a soldering iron, drill, utility knife and other tools. To access the wiring, disassemble the console. If you plan to install the button in a location other than the ignition switch, be sure to hide it with a plug.
Let's consider the installation option on a VAZ 21214 (Niva). The system used will work in this way: the first time you press the button with the brake pedal held down, the engine turns on, the second time it turns off. If you press it without the brake pedal, the power unit starts and stops. When pressed with the engine running, the engine stops.
Tools and consumables
The following components will be required:
- the button itself without a lock;
- three four-contact relays with open contacts;
- one five-pin relay with closed contacts;
- rear fog lamp relay;
- wires and terminals.
Here's what you'll need to install the button:
Connection diagram
- The working contact of the relay “+” is connected to the +12V battery (colored brown).
- The enabling signal “+” is connected there.
- General “-” – to ground.
- The operating contact of the load relay is set to +12V when the ignition is on (blue wire).
- The control signal “–” is connected to the Start-stop button.
- The enable signal “+” remains empty.
How does the mechanism affect the protection of a car from theft?
Many drivers are afraid to use this component, believing that it violates the safety of the car, but this is not so - the key in the key fob will be needed in any case. If the door is not opened with a key, the button simply will not work, so theft protection is not reduced.
The start-stop button is an interesting alternative to a regular key. With it you can start the engine much faster and more conveniently. Whether to install it or not is a personal matter for each driver; it is rather a matter of habit and desire to try something new.
Many modern cars are equipped with a system called Start-Stop. It allows you to start the engine using a button rather than the ignition key. In addition to standard devices, there are universal solutions on sale that allow you to install such a mechanism on almost any car. Today we will tell you about how the keyless engine start button works, what advantages and disadvantages it has, as well as how to properly connect and install it on the car with your own hands.

This is the problem: when you autostart, you get into the car and the immobilizer is triggered every other time, and in order for the chip to work, you need to put it directly into the ring. Is it possible to remove it from the system altogether?
Please tell me how the standard immobilizer and engine autostart behave after installing this system?
There are no changes in the operation of the immobilizer, since this button is connected to the standard connector of a conventional ignition switch and only performs its function. As for autostart, you need to look at the connection diagram. But since most alarms are connected to the key, the auto start will not see this button. The button simply emits the operation of the key in the ignition switch. But there are a number of disadvantages: the car cannot start from the pusher)) and when the battery is very discharged, the button block takes on a charge and the car does not envy without lighting it.
Immo, he most likely behaves the same way as he always did. Another question is how convenient it is to use, so that there is both rfid and immo. If the RFID has a timeout of 15 seconds to start the car, then the immo transponder should be at the antenna at the time of starting? Then somehow it’s no longer sporty, with elements of a collective farm)) Like holding the remote control at the antenna while starting the internal combustion engine.
Hello, after installation my BSK stopped working, is it somehow related to the lock?
Of course, the bsk is connected to the lock =) it receives power after turning the key =) Orange wire.
Hello, after installation my BSK stopped working, is it somehow related to the lock?
In many recent car models, a button is used to start the engine instead of the usual key. How much better and more convenient it is - everyone determines in accordance with their preferences. The appearance of such a new product has caused many drivers to want to install a push-button engine start on their old cars. Therefore, it would be quite appropriate to consider how the ignition and engine starting system can be redesigned in accordance with new trends.
Advantages and disadvantages of the Start-Stop system
Start-Stop Engine is far from a new development by specialists. Although the system is constantly being improved, experts have not yet been able to resolve the nuances associated with certain “cons” of this function. Of course, each driver must weigh everything himself and analyze whether he needs an engine start button.
Advantages:
- the engine starts with a light click;
- installing a “Start-Stop” button instead of the ignition switch is possible in any suitable place;
- no need to carry the ignition key;
- additional protection from intruders (analogue of an immobilizer).
Flaws:
- to start the engine you need to press the brake pedal, you need to get used to this, novice drivers may have certain difficulties;
- the need for improvement when using an alarm system with auto start;
- the need to dismantle the standard steering wheel lock or keep the key in the ignition switch;
- Installing a security alarm on a car with an engine start button requires additional manipulations and is more expensive.
Wiring
Main terminal on the button block.
Black - mass. We connect anywhere to the body. Red - 12th century We connect to the Red one on the terminal from the lock. We connect brown with white - turn on the ignition. Connect to pink/black Yellow - starter. Connect to yellow/blue. Blue - ACC (first position to turn on the radio) Connect to red / white Connector with two wires (brown and green) Brown is not used Green - brake pedal. Connect with the green one on the brake pedal sensor. Button labels can be disabled. We bring it to the antenna, wait for short signals, do not remove the mark, wait for two more longer signals, remove the mark. Now you can use the button without labels. (Convenient when the car is in service) It’s easy to get the tags working again. Apply the tag and remove it after the signal. The tags are activated. There is a StarLine a93 signaling. After installing the button, autorun works. IMPORTANT regarding autostart: on a manual transmission, in order to activate autostart, the immobilizer chip (standard) must be attached. Only then can you press the brake pedal and briefly press the button.
IMPORTANT regarding the immobilizer and tag antennas: They should be at a distance no closer than approximately 25-30 centimeters. Otherwise, the regular one stops seeing the key chip.
Sorry for the Russian language, I didn't study well. I loved to go for walks)))) If you don’t understand, ask here in the comments to the post.
Hi all! The topic of our conversation will be installing the Start Stop button. Lately they have been talking about this more and more often, so I decided to provide some clarity regarding the possibility and feasibility of such a step.
In reality, everyone strives to improve their own comfort and make life easier. There are many examples. Cars are equipped with cruise control so as not to constantly hold the gas pedal. We also connect rear view cameras so that you don’t have to lean over the seat and twist your neck back and forth. And navigators have completely replaced old paper maps.
As for installing a simple button instead of the ignition switch, it is quite convenient, and even fashionable. Similar autostart is provided for many modern cars. But owners of old cars can only install the button with their own hands.
The circuit is not the most complicated, which has caused a real wave of popularity for altering the ignition system. Whether to do this or not, everyone decides for themselves.
Button installation and connection methods
The following connection diagrams for the Start-Stop button are usually used:
- With or without ignition key. When this option is selected, the key is used to turn on the ignition. But the engine is started using a button. The second method involves completely dismantling the ignition switch. The ignition is turned on and the power unit is started without using a key.
- Turn on the ignition. There is an option in which pressing the button turns on the ignition, or an option in which the ignition is turned on simultaneously with the starter being activated.
- Single or long press. When using the first method, pressing once will cause the starter to rotate until the engine starts. And the second method involves rotating the starter until you release the button.
It is noteworthy that all these options can be combined with each other, since everyone has their own preferences. In most cases, installing the device does not require any special skills. Everything is intuitive; you just need to understand the connection diagram provided by the manufacturer and follow the instructions.
How the Start/Stop button works
Before starting all the work, it is important to understand the fundamental features of the device and understand the intricacies of its operation.
Without going into details, the procedure for activating this system itself consists of sequentially performing the following steps:
- disabling the alarm;
- pressing the brake pedal;
- pressing the treasured button.
The last action involves briefly starting the car starter. In order to turn off the car, you should press the same brake pedal all the way and press the magic button.
Execution of the presented algorithm will lead to the desired result only if a number of certain conditions related to the installation of working units and elements are met.
Such a superficial analysis of the system’s operation, however, does not give the car enthusiast a clear idea of its functional features. For a more thorough acquaintance with the operating features of the device, it would be advisable to study the circuit diagram of its connection, which is attached below.
Pros and cons of the device in the car
According to established tradition, let’s try to find out what positive and negative aspects are hidden in installing a “start-stop” button.
Let's start, perhaps, with the positives. If you believe numerous reviews, there are much more of them than there are minuses.
So, the presence of the presented system allows:
- simplify the engine starting procedure;
- increase comfort;
- improve the car's anti-theft system;
- save time.
If we talk about the negative phenomena associated with the installation of such a device, it is worth noting that they are all rather indirect in nature.
For example, in this case the driver has to get used to an unusual algorithm of actions for a long time. Some difficulties may also arise if the car has an autostart system.
In this case, in order to eliminate the possibility of malfunctions in the operation of the presented device, it becomes necessary to carry out work to reinstall the working module of the key fob. This will require the intervention of specialists and, as a result, unnecessary expenses.
Assembly and installation of an engine starting system with a button
The first stage is preparing the place for mounting the Start-Stop Engine button. Some car enthusiasts prefer installing a mechanism instead of a standard ignition switch, others mount the part on the front panel or on the other side of the steering column. If you intend to leave the ignition switch in its original place, we recommend that you disguise it with a suitable cap. Do not forget that the button usually has LED backlighting, so it is better to mount it so that it does not blind you in the dark.
Installing the “Start-Stop” button from Aliexpress
In most cases, it will be most advisable to purchase a ready-made installation kit. Typically it consists of the button itself, a control unit, a reader, key fobs and a set of wires. The cost of this set in the popular Chinese online store Aliexpress is about $25. This is where you usually buy an installation kit for starting the engine with a button.
Button connection diagrams (in Russian and English)
The published schemes have minimal differences, but the principle is the same.
We will consider the procedure for installing the device on a VAZ car (Lada Kalina) while maintaining the possibility of using the standard ignition switch. In this case, only the steering wheel lock is missing. If the push-button mechanism fails, you can turn it off, connect the standard ignition switch connector and start the engine using the key. To maintain this possibility, it is recommended to purchase a block with wires for the ignition switch contact group.
Installation and connection sequence:
- Remove the ignition switch by removing the four screws using a screwdriver.
- Disassemble and remove the steering lock mechanism.
- Disconnect connectors.
- Disassemble the contact group housing and remove the immobilizer antenna.
- Install the engine start button in the selected location.
- Solder the wires according to the diagram, insulating them with heat shrink. Remove unnecessary wires from the block.
- Install everything in reverse order.
- Connect the green wire to the brake block (contact No. 4, in our situation - red). A “+” should appear on this contact when you press the brake pedal.
Checking the system operation:
- Initially the button is inactive;
- To unlock, you need to bring the key fob from the kit to the reader (a double signal should sound);
- If there is no button press within 15 seconds, automatic blocking will occur (a single signal will sound);
- after unlocking, the first press turns on ACC (in our situation it is not used), the second press turns on the ignition, the third turns off the system (if you do not first press the brake pedal);
- With the brake pedal pressed, pressing the button a third time will start the engine;
- quick start of the engine is possible - you need to press the brake pedal and simply hold the button for 1-3 seconds until the power unit starts;
- To stop the engine, press the brake pedal and press the button.
Installation recommendations
Before starting work, you should take preparatory measures. A lot depends on what kind of machine you are dealing with. Some people remove the car ignition switch itself by installing a simple key in its place. In other situations, a hole is made to size, allowing access to the wiring and allowing connection to the electrical circuit.
To work you will need a set of tools and some materials, consisting of:
- screwdriver;
- wire cutter;
- electrical tape;
- ready button;
- three four-pin relays;
- one five-pin relay;
- one relay from PTF;
- a set of insulated wiring with terminals;
- free time;
- installation instructions.
If you buy a ready-made kit, then you are doing absolutely right. The package includes everything you need, plus a detailed installation manual and the installation diagram itself. It is from this instruction that you need to build on, and not look for some universal guides.
For those who understand the electrical equipment of cars, the diagram below will be a clear example. This is the simplest algorithm that allows you to set keys to start the power plant by simply pressing a button.
If this picture doesn’t tell you anything at all, then taking on such a task is strictly prohibited.
The bottom line is to make three connection points in your car. The first will be located on the ignition block of your car, the second will be placed on the brake pedal limit switch, and the third will be placed on the control wire.
Whether to install such a solution or not, everyone decides for himself. Carefully consider the advisability of changing the engine switching principle on your car. Experience shows that the button is not suitable for everyone. That’s why many people change back Start-Stop to the usual key turned in the ignition switch.

One of the features of expensive cars is the presence of an engine start/stop button instead of the usual ignition key. AvtoVAZ does not yet provide the “Start the engine with a button” option, but any owner of a Lada car can modify the design with their own hands.
Below are two diagrams for connecting the start/stop button:
- Installation of a ready-made kit with a button, control unit and wires (price about $35), see the Aliexpress catalog;
- Self-production of one of the most popular circuits based on automotive relays (costs about $6).
In both cases, the scheme can be implemented on any Lada car (XRAY, Vesta, Largus, Granta, Kalina, Priora or Niva 4x4), including foreign cars. The button is installed in place of the ignition switch.
The ignition switch can be:
- put away;
- leave. Connect the start/stop button to the ignition switch connector (allows you to return to the key-start scheme within 10 minutes), and to prevent the steering wheel from being blocked, leave the key cut off and turned in it.
Car safety issue
Drivers often like this system, but they are in no hurry to install it, worrying about protecting the car from theft. In fact, in this regard, everything is thought out - you will not be able to start the engine without the key fob.
The Start-Stop Engine button is a rather interesting function, which is most often implemented by tuning enthusiasts in their cars.
If desired, a true car enthusiast can do anything. And this is not a joke, but the real state of affairs. But more often we try to make management more comfortable, to remove useless and routine operations. Try replacing the key and installing the start-stop button yourself according to the diagram below.
The car's ignition key has long lost its original security functions; if your car has a full-fledged high-quality alarm system, the point of using the key will remain only to bypass the immobilizer or open a frozen door in winter.
Installing a start-stop button instead of the ignition switch
It is clear that the first point is more like an imitation of a start-stop button, but for adherents of this idea there is a completely reasonable justification. The button takes on the functions of an additional service mechanism, which is especially valuable in city driving conditions. At the same time, the lock is less likely to break, and the home-grown start-stop may well “earn extra money” as an additional anti-theft feature.
The first start-stop option is simple, but tasteful
The start-stop button can be made from two relays for the rear fog lights, No. 22.3777. A set of two pieces, with a backlit button, will cost about four hundred rubles. You can throw in any diode you find; there are no large currents there.
Assembling and connecting the circuit is not particularly difficult; you only need an additional piece of wire with double the copper cross-section. We connect it to the 30th leg of the starter relay and connect it with the 87th ignition relay, everything is pink in the diagram. How to connect the wires correctly is clearly understood from the photograph.
If you add a little spare parts and imagination, you can assemble a safer version of the start-stop button with your own hands. This circuit adds a pair of relays and a limit switch for the clutch pedal. Despite its apparent uselessness, a normal, high-quality trailer will greatly protect your supercar from possible surprises, especially if there are teenagers or unpredictable people in the car. In this case, starting the engine will require disengaging the clutch.
It is clear that there should be no trace of play in the clutch pedal.
The relay circuit allows you to easily monitor the performance and even expand the circuit. In some cases, craftsmen use an additional built-in limit switch in the seat of the driver's seat, which closes under the weight of a particular driver, so that a curious passenger does not cause trouble with playful hands.
The logic of the start-stop button is quite transparent. The first long press starts the motor, the second press stops the motor. Such a scheme is reliable, but only if the button operates normally. If there is rattling or unclear activation, it often leads to problems and injuries.
It is recommended to choose the location of the start-stop button taking into account dust protection, preferably away from the eyes of those present in the cabin.
The most interesting option for the very smart
Unlike previous schemes, this version of the start-stop button is built on a microprocessor, so it is difficult to recommend it for production if you do not have the appropriate knowledge of the basics of microelectronics. But for general interest, it is simply necessary to familiarize yourself.
The proposed start-stop system has several undeniable advantages:
- the engine is not sensitive to the rattling of the start-stop button, that is, if the contact is accidentally briefly closed or pressed, the engine will not be stopped;
- the author of the idea included in the program logic the mandatory pressing of the brake pedal and lever, which may make the circuit suitable for automatic machines;
- the system checks the start result based on the jump in oil pressure, so the likelihood of the starter wedge when the engine is running is sharply reduced.
You can start the start-stop circuit yourself after disabling the alarm by long pressing the button without a lock; if unsuccessful, the parameters will be reset and will be ready for a new attempt. The engine is stopped by briefly pressing the brakes.
It would be a sin not to automate the launch process itself. The guy included a simple solution in the circuit - pressing the start-stop button once causes the system to try to start the engine three times, with a short interval. Holding the button for a long time turns the starter until a sign of engine operation appears.
The advantage of this approach is the widest space for creating a variety of conditions for connecting the start-stop button and starting the engine in the most difficult situations. But it’s not enough to just make a circuit; it still needs to be programmed correctly. All operating logic is organized on the PIC16F84A processor, the connection of power circuits is controlled on the KT817G, they have a considerable current reserve.
The start-stop button design is interesting, but, like all experimental options, it requires testing for fault tolerance. Any microelectronic gadgets do not tolerate heat overload and sudden voltage surges. In addition, it is necessary to check the compatibility of the oil pressure sensors, the handbrake and other sensors involved in the vehicle’s electrical system.
