The key that has the transponder chip can be referred to as a 'fob' or a smart key because it is much more difficult to clone than a conventional mechanical key. It is possible to duplicate a standard key but not a transponder key. Unlike the central locking element remote of a conventional key which is powered by batteries the transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy that is absorbed by the microchip in the key. The chip then responds with an individual code to the immobiliser inside your car.

Some models even notify the owner if they try to use an unapproved fob or key.
