Transponder chips are a typical feature of modern automobiles and are designed to stop car theft. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then recognizes the signal and starts the engine if it matches the original frequency that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it difficult for novice car thefts to wire a vehicle hot and then turn it on.

The chip and the key are connected via a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This generates a signal, which is absorbed by the coil and sent to the key's 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.
