Transponder chips are a typical feature of modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is put into the ignition. The car then scans for the signal and starts the engine in case it matches the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it harder for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition, a magnetic field is created around the transponder. This generates a signal, which is received by the coil before being sent to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it matches the engine will start.
