This makes it more difficult for novice car thefts to hot-wire a vehicle and then turn it on.

A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is received by the coil and sent to the key's identification number. The key's identification number is then sent back to the car and the engine is started when the identification number matches.
