Transponder chips, which are used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted into the ignition. The car then scans for the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
A circuit board that has an induction coil connects the chip to the key. When the key is put in the ignition it creates a magnetic field generated around the transponder. This generates a signal that is absorbed by the coil and sent to the key's identification number. The key's identification code is transmitted back to the car, and the engine starts if the identification number matches.
