Transponder Keys

It is designed to ensure that only the correct key can be used to start the engine and also prevent theft. Contact your local dealership or locksmith to see a demonstration of this technology.

When the transponder is put in the ignition, the key sends a message to the chip that is inside the engine control unit (ECU) of the vehicle.
