Transponder chips, used to protect cars from theft, are a common feature of modern automobiles. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then scans for the signal and starts the engine if it matches the original signal that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it much harder for novice car thieves to wire a vehicle and then start it.
A circuit board with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal, which is received by the coil and then transmitted to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
