This chip transmits a code to the car's immobilizer unit that can be integrated into the PCM, BCM, the instrument cluster smart junction box, or standalone module.

Using specific techniques, it is possible to copy a standard car key but not a transponder key. In contrast to the central locking element remote of a conventional key which is powered by batteries the transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder has to be in the ON position. The ring emits IR energy which is detected by a microchip within the get more info key. The chip then responds with a unique code to the immobiliser of your car. The car's computer checks the code stored in its memory with the one from the transponder chip, and If they are compatible, the engine will start.
