Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and starts the engine if it is in line with the original one that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incompatible frequency. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.

This generates a signal that is absorbed by the coil and sent to the key identification number. The key's identification number is sent back to the car and the engine will start when the identification number matches.
