Utilizing special methods, it is possible to copy a conventional car key, but not the transponder key. Transponder chips are powered by an infrared signal and not battery power.

To activate the transponder chip the ignition cylinder must be switched to ON. The ring emits a blast of IR energy that is absorbed by the microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer checks the code in its memory with that from the transponder chip and when they match the engine will be able to start.

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