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

The chip responds by sending a unique code your car's immobiliser.
