Using special techniques, it is possible to copy a conventional car key however, not transponder keys. Transponder chips are powered by an infrared signal not battery power.

To activate the transponder the ignition cylinder has to be in the ON position. The ring emits IR energy that is picked up by a microchip inside the key. The chip responds with an individual code to the immobiliser in your car. The car's computer examines the code in its memory to the transponder's and when the two codes match, it will start the engine.

The system won't permit the car to start if it doesn't receive the correct code, and some models will even report back to the owner in the event that someone attempts to use an incorrect key or fob.
