The chip transmits a code from the key or fob to the immobilizer unit of the car, which can be integrated into the PCM (power control module) or BCM (brake control module) instrument cluster smart junction boxes or standalone modules.

With the help of special techniques, it is possible to copy a standard car key, but not a transponder key. In contrast to the remote central locking element of a conventional key that relies on battery power, a transponder chip powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy which is absorbed by the microchip within the key. The chip then sends a unique code to the immobiliser in 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 begin the engine.

This will reset the system and allow it to accept your key once more.
The security light is the car immobiliser's way of telling you that there is an issue with the system. If the light is illuminated and you attempt to start your car, it means that the code that is stored in the ECU does not match the chip inside the key.
