Transponder chips are a common feature of modern cars 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 it matches the original one that was programmed in the vehicle. The car will also shut down if the frequency is invalid. 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 placed in the ignition it creates a magnetic field around the transponder. This generates a signal that is absorbed by the coil and then transmitted to the key identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will start.
