Transponder chips, used to prevent car theft, are a common feature of modern cars. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.
A circuit board equipped with an induction coil connects the key to the chip. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This produces a signal which is taken up by the coil, which then transmits it to key's identification number. The key's identification code is sent back to the car, and the engine starts when the identification number is in line with.
