Utilizing special techniques, it is possible to duplicate a standard car key however, not transponder keys. In contrast to the remote central locking element 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.

The chip then sends an individual 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 If the two codes are identical, it will start the engine.
