With the help of special methods, it is possible to duplicate a standard car key however, not transponder keys. Contrary to the central locking element remote of a conventional key which is powered by batteries, a transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
