Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car can detect the signal, and starts the engine only if the signal matches the one programmed in the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.
The chip and the key are linked by the circuit board which 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 amplified by the coil which then transmits it to key's identification number. The key's identification number is then sent back to the car, and the engine starts when the identification number matches.
