Transponder chips, which are used to protect cars from theft, are a common feature of modern automobiles.

This makes it much harder for novice car thieves to connect a vehicle with hot wires and then start it.

This creates a signal which is absorbed by the coil and sent to the key's identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.
