This makes it much harder for novice car thieves to connect a vehicle with hot wires and then start it.
The chip and the key are connected via a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This produces a signal which gets absorbed by the coil, which then transmits it to key's identification number. The key's identification number is then transmitted back to the car, and the engine starts if the identification number matches.
