The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it harder for novice car thefts to hot-wire a vehicle and then start it.

The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. This produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The key's ID number is transmitted back to the vehicle and if it matches, the engine will start.
