In modern mid-range cars, the usual ignition switches with a key are becoming less and less common, which have been replaced by more stylish, compact and easy-to-use start buttons. Many car owners are trying to implement such a device into the design of their own car, often using ready-made “Start-Stop” kits. It turns out differently, but experts will help you figure out whether the game is worth the candle.
Classic modernization methods
Since the ignition key in the usual sense is becoming a relic of the past, folk craftsmen are trying to correct the situation on their own. And as it turned out, modern Kulibins have already managed to invent several methods for such re-equipment, requiring a minimum amount of time, effort and financial costs.
The simplest of them is to install a start button along with a key, that is, we are talking about a partial modernization.
The operating diagram of such a device involves initially inserting the key, turning it and then starting it directly through the button itself.
The engine will have to be turned off in the same way, only in the reverse order, which ultimately calls into question the feasibility of such a decision.
As for the diagram, it looks like this:
The second scheme allows you to do without a key, which is why it is in great demand, but requires certain skills and effort.
The costs will also be impressive, since the car owner will have to fork out for a special relay and button illumination, powering it from the battery or vehicle alarm.
However, activation of one device will inevitably lead to deactivation of another. You will also have to abandon the steering wheel lock, which will not have the best impact on safety. In this case, the diagram of such a starting device will look like this:
There is another option for arranging the “Start-Stop” button in a car, however, it is practically no different from the second one. The only difference will be that when the button is pressed, the relay will start, and not the starter, as in the second circuit.
Installing the engine start/stop button (ready kit)
The easiest option to start the engine with a button is to buy a kit, which in a Chinese store is called something like this: “push start button start/stop car engine function working with car alarm system and remote central lock blue color back light.” Judging by the name of the product, the button and control unit can be connected to the alarm.
The most popular among car enthusiasts is the scheme where the engine starts with a button while the brake pedal is pressed. All presses are short, that is, you do not need to hold it for the starter to operate. This is exactly the algorithm we get:
- One press - ACC mode;
- second press - ignition is on;
- third press - ignition is turned off;
- To start the engine, you need to press the brake pedal and briefly press the start/stop button (if it doesn’t start well, you can press and hold the button, then the starter will work).
Universal connection diagram for the start/stop button included in the kit:
Now you can only carry the alarm key fob in your pocket.
Combined modification option
As practice shows, a combined conversion scheme can be implemented even by a novice motorist who is at least a little familiar with the electrical structure of his vehicle. To do this you will need to acquire the following components:
- ZPTF relay;
- 4-pin relay;
- 5-pin relay;
- engine start and stop button;
- diodes and terminals.
Having prepared everything you need, including tools (nippers, pliers, insulating tape), you should connect the contacts according to the diagram with further installation of the diode, which can be installed almost anywhere.

Ready-made universal kits
If you wish, you can purchase a ready-made kit for such a modification. Among all the abundance presented, the following universal options are distinguished:
- Sets with key and start button. The system turns on the engine only after turning the key in the ignition switch.
- A keyless option with a more complex installation scheme.
- A push-button starting device with a short press, which starts the engine literally in a second of holding, which will be quite enough to fully crank the starter.
- A long-press device that requires more time to turn on the internal combustion engine, allowing the driver to control the rotation of the starter himself.
If any difficulties arise with the installation of any of these kits, you can always solve the problem with the help of specialists.
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.
Advantages and disadvantages of the “Start-Stop” option
Like any other modernization, converting a conventional key-based ignition to a push-button one has its pros and cons. The first of them include:
- Quick and easy starting of the internal combustion engine.
- No need to carry the ignition key with you.
- The ability to move the button to any other place, which allows you to increase the ergonomics of the device.
- Compatible with alarms, immobilizers and other car security systems (relevant for certain kits).
- Possibility of closing the vehicle by pressing a button without activating the alarm and other anti-theft devices.
The main disadvantages of the scheme today are the following points:
- The need to press the brake pedal before starting the engine.
- Possible difficulties when installing an alarm system with a warm-up function in a vehicle, which can only be solved by integrating the chip from the key fob into the car system.
- Higher price tag for alarm installation.
You can finally decide on the advisability of installing a button instead of the usual key only after weighing all the pros and cons. And, of course, you shouldn’t play such toys on old representatives of the domestic automobile industry, so as not to turn your faithful iron horse into an outright ridicule.
Hidden Features
Many car owners are sure that such an engine start button is intended solely to turn on the engine. However, many automakers have provided this system with additional capabilities, which can significantly increase the comfort of using the car or ensure its necessary safety. For example, on many Volkswagen / Audi cars, such a Start/Stop Engine button has an additional function of activating a mechanical steering lock. All the car owner needs to do is, after turning off the car, press the button again and lock the steering wheel. Of course, it will be impossible to completely ensure the safety of the car in this way, but it is quite possible to make it more difficult to steal.
Also, using such a push-button start system, you can emergency stop the engine, even if the gearbox is faulty and the selector is locked in the Drive position. In such a situation, it would be impossible to simply turn off the engine, since the system believes that the car is moving and stopping the engine is impossible. To turn off the engine using this forced method, hold down the Start/Stop Engine button for 5 seconds and simultaneously press the brake pedal. At the same time, the security system monitors the speed of the car and turns off the engine only if this parameter exceeds 10 km/h.
Electronic ignition switch
Manufacturer: Novels - Russia
Installation: depends on equipment and vehicle. The electronic ignition switch (EIS) is a complete replacement for the standard mechanical ignition switch of a 12-volt car.
The electronic ignition switch is available in the following configurations:
- EZZ Lite – comes without an “Engine Start Stop” button. If there is already a button, or you plan to start the engine with a standard or hidden button, this is the most suitable configuration option. It is possible to block the engine from unauthorized starting by connecting the lock module to an existing car alarm, or using a secret toggle switch.
- EZZ Base – the engine starts by pressing the included button. It is possible to block the engine from unauthorized starting by connecting the lock module to an existing car alarm, or by installing a secret toggle switch. Can subsequently be equipped with an electronic key reader.
- EZZ Dallas – authorization of the owner is carried out using an electronic tablet key, using a non-contact method. To authorize, you must attach the tablet to the reader. Arming occurs automatically after 3 seconds. after turning off the ACC mode.
How to install a mechanism in a car
Before you begin installing the start/stop button, it is necessary to carry out certain preparatory work, which will depend on the car model. The ignition switch is removed from the car. And if the design of the car does not allow this, then a small hole is made on the dashboard, next to the lock. To cut through it, any available tool will do: a knife or an ordinary household soldering iron. This hole will give access to the wiring (you can make a plug for it later).
Next, we consider the simplest and most accessible option for installing a button, which will work like this: the first press of the key in combination with the pressed brake pedal will start the engine, the second press will turn it off.
Consumables and tools
To install the device you will need:
- start/stop button;
- three relays with four contacts;
- one relay with five contacts;
- one relay for fog lights;
- set of insulated wires with terminals.
Sequence of operations when installing “start/stop” on the ignition switch
To properly install the device into the system, you must follow the sequence of steps below:
- First, the ignition lock cylinder is removed, followed by the lock itself.
- The wiring going to the ignition unit is insulated with electrical tape, after which the button from the kit is connected to them in accordance with the previously selected circuit.
- After connection, the key is mounted on the dashboard or in any other place convenient for the driver.

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.
But a few of the most popular solutions dominate. These are the options that car owners prefer. Let me introduce you to them:
- Button with ignition key. This system will not allow you to start the car without using the ignition key. Therefore, you need to turn the key itself in the lock, and then press the button;
- Keyless. To start the motor, you just need to press the button. An extremely convenient scheme. But here it is important to install it correctly, otherwise the car will be extremely easy to steal;
- Short press. To start, hold the button for up to 2 seconds. The starter rotates and turns off when the engine is running;
- Long press. Allows you to hold a key as long as required. The starter will not stop rotating until the engine starts;
- A circuit where the ignition is activated after a key has been pressed;
- A scheme in which the ignition is activated 1 second earlier than the car starter.
Also, some combine different schemes to achieve the desired result.
If you do not have experience in such work, and also have poor understanding of automotive electrical equipment, you should not take on such work with your own hands.
Contact good workshops. Moscow alone is ready to offer dozens of addresses of car services that offer similar services. The price will be higher, but the result is guaranteed.
How does the button affect anti-theft protection?
In most cases, the presence of the device does not affect the safety of the car in any way. Because the vast majority of modern schemes somehow provide for the use of a key in the car key fob. That is, if an attacker opens the door without the help of the “original” key, the “start/stop” button simply will not start the engine.
Problems can arise when the key fob is excluded from the scheme. This usually happens when the installation of the mechanism is carried out by amateurs. The solution is simple: entrust the installation of the button to professionals.
So what does the start/stop button do? Firstly, comfort, and secondly, saving time. The last point is especially relevant in the modern world, where people are constantly in a hurry to get somewhere. To install a button according to the simplest scheme, no serious knowledge of electrical engineering is required. All a beginner needs is to carefully study the diagram included with each kit and not confuse the colors of the wires.
A modern car can be started not only with a key. The Start-stop button is a small product that is installed instead of the ignition switch or in another part of the cabin. One click is enough to start the car. Everything is simple and convenient. How to install the “Start-Stop” button with your own hands will be discussed below.
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.
