Using specific methods, it is possible to copy a conventional car key but not a transponder key. Unlike the central locking element remote of a conventional key, which is powered by batteries, a transponder chip powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.

The chip responds by sending a unique code to the immobiliser of your car. The car's computer analyzes the code stored in its memory to the one on the transponder and when the two codes match, it will start the engine.
