This makes it harder for novice car thefts to connect a vehicle to a hot wire and then turn it on.

The key and the chip are connected via an electronic circuit board that contains an induction coil. When the key is placed in the ignition it creates a magnetic field created around the transponder.

The ID number of the key is transmitted back to the vehicle, and if it matches, the engine will begin to run.
