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