The car is also programmed to stop when it detects an incompatible frequency. This makes it harder for novice car thefts to hot-wire a vehicle 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 generated around the transponder. This produces a signal which gets amplified by the coil which transmits it to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it is in line with the engine will start.
