What is a Transponder or “chip” key?

A. A transponder key is a key that has a device embedded inside that transmits and receives data. These devices contain one of over a trillion unique codes. When the key is inserted into the ignition, the transponder sends a signal to a disc-shaped antenna mounted behind the steering wheel. If the signal is recognized by the vehicles immobilizer, then the engine will start. If the signal is not recognized or has been weakened by damage to the transponder then the immobilizer will shut down vital operating systems to the engine and it will not run. This technology greatly reduces the risk of auto theft and provides a peace of mind for the vehicles owner.
