The car detects the signal, and starts the engine only if the signal is in line with the one programmed in the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to hot wire a vehicle and then start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. reprogram car key creates a signal that is taken up by the coil, which sends 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.
