What are transponder keys?
The biggest change to the automotive industry in recent times has been the introduction of the built in immobilizer system on all cars manufactured since 1995 (late '94 in some cases). This involves placing a microchip in the head of the key, which is a miniature transmitter and receiver. There is an engine management system in the engine compartment that can recognize the signals transmitted from the key. If the correct signals are not detected the engine will not start.
