Keys

Nearly all modern vehicles require some kind of transponder key or fob in order to operate, providing security and anti-theft protection.

Transponder chips are a standard feature in modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and starts the engine in case it matches the original signal that was programmed into the vehicle. The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it much more difficult for novice car thieves to connect a vehicle with hot wires and then start it.

The chip and the key are connected by a circuit board that includes an induction coil. When the key is inserted into the ignition, it creates an electric field around the transponder. This produces a signal which is taken up by the coil, which sends it to the key's identification number. The key's identification number is transmitted back to the car, and the engine starts if the identification number matches.
