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

The chip then sends a unique code to the immobiliser in your car.
