Using special methods, it is possible to copy a conventional car key but not a transponder key. In contrast to the central locking element remote of a standard key that relies on battery power the transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

The chip responds with an unique code to the immobiliser inside your car. The car's computer compared the code stored in its memory to the one from the transponder chip, and when they match the engine will begin to rev.
