This makes it more difficult for novice car thieves to connect a vehicle with hot wires and then start it.
The chip and the key are connected by an electronic circuit board that contains an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This generates a signal that is taken up by the coil and sent to the key identification number. The key's identification code is transmitted back to the car and the engine will start if the identification number matches.
