In contrast to the remote central locking element of a conventional key that relies on battery power the transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a flash of IR energy that is picked up by the microchip inside the key. The chip responds by sending a unique code your car's immobiliser. The car's computer checks the code stored in its memory with the one from the transponder chip, and if they match, the engine will start.
