This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and start it.

A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition, a magnetic field is created around the transponder. This produces a signal which gets amplified by the coil which sends it to the key's identification number. The key's identification number is then transmitted back to the car, and the engine starts when the identification number matches.
