It is possible to duplicate a standard key but not a transponder key. Unlike the central locking element remote car key repair of a conventional key, which uses battery power the transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.

The chip then sends a unique code to the immobiliser inside your car. The car's computer examines the code in its memory to the one on the transponder and when the two codes match, it will start the engine.
