The car is also programmed to stop when it detects an incompatible frequency. This makes it more difficult for car thieves with no experience to wire a vehicle and start it.

A circuit board equipped with an induction coil that connects the chip to the key. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is taken up by the coil and then transmitted to the key's identification number. The key's identification code is transmitted back to the car and the engine will start when the identification number matches.
