It is also known as a "chip key" or a "transmitter-responder" key. Its function is to prevent your engine from starting when you have a duplicate of your key. It functions by sending an audio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer matches the signal sent by the key the immobiliser will be disarmed and the engine will begin to run.    The key with the transponder is also referred to as a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. It is possible to duplicate a traditional key but not a transponder key. Contrary to the central locking element remote of a standard key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.    To activate the transponder chip, the ignition cylinder must be switched to ON. The ring emits a blast of IR energy, which is detected by the microchip in the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer analyzes the code stored in its memory to the transponder's code and when the two codes match, it will start the engine.    If the immobiliser detects that an unauthorized transponder or key is in use, it will disable the engine and prevent the essential components from working.

This will reset the system and allow it to accept the key again.    The security light is an immobiliser's way of warning you of a problem. If you attempt to start the car but the light stays on it means that the chip inside your key isn't in sync with the code that is stored in the ECU. This can occur in the event that your car's key was replaced with a new key that's not programmed to work with the vehicle, or if the ECU has been swapped incorrectly.    If this is the case you should take your key or transponder chip to a professional for them correctly programmed for the vehicle you are driving.

However, this method is extremely risky and requires a great deal of experience in order to do it without cutting yourself. Modern car thieves are using more advanced methods, such as Bluetooth or other apps that take over a car's data and remotely manage it.    Car owners are often faced with warning lights that indicate the immobiliser has gone off the rails.
