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