The car is also programmed to stop when it detects an incorrect frequency. This makes it much harder for novice car thieves to hot wire a vehicle and then start it.

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