The car is also programmed to stop if it detects an invalid frequency. This makes it more difficult for thieves who are not experienced to hot wire a vehicle and start it.
A circuit board with an induction coil that connects the chip to the key. When the key programmers is put in the ignition it creates a magnetic field generated around the transponder.
