Utilizing specific techniques, it is feasible to copy a conventional car key, but not a transponder key. Unlike the remote central locking element of a standard key which uses battery power the transponder chip here is powered by get more info an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
