Utilizing special techniques, it is possible to copy a conventional car key, but not transponder keys. Unlike the remote central locking element of a conventional key, which uses battery power, a transponder chip powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.

To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a flash of IR energy which is absorbed by the microchip inside the key. The chip responds by sending a unique code to the immobiliser of your car. The computer in the car analyzes the code stored in its memory with the transponder's and if the two codes match, it will start the engine.
