Button to start the engine with your hands
In modern cars, you can increasingly find solutions, which allows you to start the engine by simply pressing the Start Engine button. Having such an option means, that there is no need to use the ignition key, the procedure of starting the engine itself becomes simpler and more convenient.
We also recommend reading the article about it, what is engine warm-up. In this article you will learn about it, why many car owners prefer to install additional "mass" in the car and how to warm up the engine itself.
Today is the engine start button (starter button) can be installed in almost any car, which is not normally equipped with the ability to start the engine without a key in the ignition. Next we'll talk about that, what are the pros and cons of the car owner after installing the engine start button, and also we will consider the most widespread schemes and ways of independent installation of the button of start of the motor.
Keyless engine start button
Quite obviously, that the starter button in the car increases the ease of operation of the vehicle. The standard versions require the obligatory combination of such a Push Start button with the possibility of keyless access Key-Less-Go. This combination saves the owner from having to use the usual ignition key, replacing it with a so-called electronic key.
Without going into details, electronic key is a label, by which the owner is recognized and other anti-theft systems of the car after approaching the vehicle at a certain distance. As for the start button of the internal combustion engine, it will work only if the electronic key is in the car.
In practice, it looks like this:
- the owner of the electronic key approaches the car;
- at a certain distance the car system recognizes the owner, exchanging signals with an electronic key label;
- then the owner presses a button on the electronic key or simply approaches close to the car;
- then the door locks are unlocked;
- the driver sits in the seat and presses the engine start button;
It turns out, the electronic key is used by the owner only for forced opening and closing of car doors. All other actions are performed automatically by the keyless entry and start system. Now let's talk about self-installation of the Start-Stop Engine button.
Popular ways to install the starter button
Let's start with that, that many car owners are attracted by the ability to start and shut down the engine with a button, that is, do not use the key in the ignition. At the same time, no additional implementation of the keyless entry system is envisaged. It should be noted, that in case of such scheme of installation comfort increases, but security suffers. The point is, that after penetration of malefactors into car interior the button of start of the engine is blocked by nothing, since there are no systems, identifying the owner.
Given the above, it is recommended to equip the car with an additional immobilizer or other solutions, which prevent unauthorized starting of the engine. It should also be noted, that self-installation of the engine start button most often leads to an increase in the load on the starter. As a result, the life of this element may be reduced. Let's add, that the abnormal installation of the engine start button with your own hands can be done according to different schemes, taking into account the wishes of the owner, features of a car, etc.. d.
- One of the easiest installation options is the starter button, which provides for the parallel use of the ignition lock. With this scheme, the ignition is turned on with a key in the lock, and the engine itself is started from the button. Note, that this method has more disadvantages, than the pros, as the fact of the presence of the "start-stop" button still does not provide a proper degree of ease of operation.
- Another type of installation of starting the engine from the button is the ability to start the engine with the accelerator pedal pressed for models with automatic transmission and the clutch pedal for transport with manual transmission. This scheme involves turning on the ignition from the Start-Stop button, while starting the engine is carried out immediately after depressing the accelerator pedal or clutch.
- We should also mention the method of starting the engine from the starter button when the brake pedal is pressed in parallel. The convenience of this solution is questioned by many, especially in that case, if the machine suddenly stops in the stream. Let's add, that the start-stop button is connected to the accelerator pedals, brake or clutch in different schemes requires the installation of a separate sensor on the pedal.
- Of particular note is the installation of a "delay" engine start button. This method of non-standard installation has the least detrimental effect on the starter. The disadvantage is the complexity of installation, which requires recourse to professionals and a number of changes in various car systems.

It turns out, available installation methods can be divided into the following:
- the engine start button only activates the ignition, the start itself is carried out after depressing the brake pedal, gas or clutch;
- the start-stop button allows you to turn on the ignition, and start the engine;
- full installation of the system of start of the engine from the button in combination with installation of system of keyless access in the car;
The latter method is the most optimal and most expensive, since together with the "Start Engine" button the system receives an electronic key and interacts with the door opening extensions, burglar alarm module, etc.. d.
Self-installation of the engine start button
To better understand the issue, it is necessary to superficially consider the standard process of starting an engine on cars, which from the factory are equipped with a simple ignition lock. In such cars power wires from a starter are connected to contact group of the ignition lock. After turning the key in the lock, the contacts close. This solution is found on older car models. The point is, that a large current passes through the contacts, which leads to rapid burnout.
For this reason, more modern versions have a separate relay. The task of such a relay is to take all the load on itself and close the contacts after turning the key in the ignition. Ability of the relay to cope with high loads, and also simplicity of replacement of the given element in case of its failure of the last allows to speak about reliability of system. As a result, the service life of the contact group has increased significantly.
To connect the engine start button, you need to determine exactly, which contacts are responsible for power supply to the starter, which allows you to scroll the crankshaft with the starter and start the engine, and stop the power unit by opening the contacts. These contacts are connected to the start button of the engine or other elements (depending on the installation scheme), allowing to do completely without a key in the ignition lock.
pay attention, this manual is not an exact scheme for installing the engine start button and is for informational purposes only.! If you do not have sufficient experience with electrical equipment, then it is recommended to refrain from such actions completely. Remember, connection errors can lead to a short circuit in the car's on-board network, failure or failure of electrical equipment, fire and other consequences.
- To connect, you must remove the decorative and protective elements on the steering column, to access posting. The ultimate goal is a connector, located on the rear side of the ignition lock contact group. The specified connector must be disconnected by snapping off the special catches. On machines without relays you will need to find power wires in the contact group, which are directly connected to the starter contacts. To accurately check, you can turn on the ignition in the lock with a key, then close the found wires (most often, these are two wires with a large cross section). Starting the starter after closing the wires will indicate that, that the contacts are selected correctly.
- The next step is to connect the "start-stop" button. To begin, you need to choose the location of the button on the torpedo or other appropriate place, then connect the required power wires from the ignition lock contact group to it. On machines from the relay wires are connected to the starter button, which supply voltage to the relay. You can use a multimeter to determine exactly, on which the ohmmeter mode for resistance measurements is exposed. First, the tester checks the wires from the starter to the car body, resulting in a "minus".

- Next, the remaining wiring is measured voltage, by switching the multimeter to the appropriate mode. To measure, touch the wire with one probe, and others to the body of the vehicle. The main task is to identify the wire, on which 12V appears in the ignition lock after turning the key. Additional measurements will also be required once this wire is detected. To do this, the tester in the voltage measurement mode determines the contact, at which the voltage is equal to a constant 12V relative to the mass. Then the key turns on the ignition, but the key does not move to the "start" position. The found wire is re-checked for the absence of "calls" with the ground and shorting to the body. It is also necessary to check for the presence of voltage in the specified wire after turning on the ignition and subsequent transfer of the key to the "start" mode.
- A separate piece of wire should be prepared to complete the diagnosis, which connects to the contact, on which voltage was previously detected after turning the ignition key. Next, you need to connect this contact with another wire, on which the presence of DC voltage is recorded. In that case, if the starter starts to spin after shorting these wires, then the required conclusions are found correctly. In other words, these contacts are normally connected after turning the key in the lock. It only remains to bring the found wires to that place, where the keyless engine start button will be installed. The final step will be to connect them to the Start-Stop Engine button.
Tips and tricks
The engine start button works like this, that the driver presses it and holds the time required to start. During this time, the starter turns the crankshaft, as a result, the engine is started. Then you can release the cap.
We also recommend reading the article about it, which is better to choose, atmospheric or turbocharged engine. In this article you will learn about the main advantages and disadvantages of turbocharged engines, and whether to buy an old petrol or turbocharged diesel car.
Note, that when choosing the start button of the engine "start-stop" it is necessary to consider a number of certain nuances. One such point is the issue of fixing this button. The best option is this, when the contacts are closed after pressing, and after release open. If the button will be fixed, then after starting the engine to open the contacts you need to quickly press it again.
As for the button itself, there are many available solutions available for free, which differ in the quality of execution, price and other characteristics. These buttons may have backlighting, are made of plastic or metal.
For these reasons, the choice should be taken into account:
- a strong current will be applied to the button;
- the solution will be used constantly;
Taking into account such features of operation it is better to choose the button of start of the engine with a qualitative external covering. (example, chrome plating). Such a product will be resistant to abrasion to maintain an acceptable appearance. You also need to understand, that cheap deals can burn out with a few clicks, so this aspect should be given special attention.
