The car is also programmed to shut down if it detects an invalid frequency. This makes it much harder for novice car thieves to wire a vehicle and start it.
The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This generates a signal, which is absorbed by the coil and then transmitted to the key's identification. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
