It works by sending the radio frequency signal from the key to the immobiliser system inside your car. If the code on the car's computer is in line with the signal sent from the key, it will disarm the immobiliser and allow the engine to start.
The key that is equipped with a transponder chip is sometimes called"fob" or a smart key because it is more difficult to copy than a conventional mechanical key. With the help of special methods, it is possible to copy a standard car key however, not a transponder key. Transponder chips are powered by an infrared signal not battery power.

The chip then responds with an unique code to the immobiliser of your car. The computer in the car compares the code stored in its memory with the one on the transponder and when the two codes match, it will start the engine.

The car immobiliser is a fantastic way to deter thieves, but it could sometimes be out of the sync. This could be due to interference or a system that is too sensitive. If this is the situation, it may need to be reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes before reinstalling it and begin the car. This will reset the key system so that it is ready to accept your keys once again.
The security light is a way of warning you of the presence of a problem. If the light is on and you attempt to start your vehicle, it indicates that the code stored in the ECU is not compatible with the chip on the key.

The system won't allow the car to start in the event that it does not receive the correct code. Certain models will even notify the owner when they attempt to use an incorrect fob or key.
The system isn't impervious to attack, but it is. Some thieves have managed to get around the immobiliser using methods like hot-wiring. This involves crossing the wrong wires in the wiring of a vehicle, which fools the ECU into thinking that the proper key or fob is being used. This is a risky technique and requires extensive experience to avoid electrocuting oneself. Modern car thieves are also using more advanced methods, like Bluetooth or other specialized apps to take over a car's data and remotely manage it remotely.
Car owners often see warning lights that signal that the immobiliser is malfunctioning. This can happen for various reasons, but one of the most frequent causes is a dead or defective battery on the key fob. A simple replacement can fix the issue.
