The energy is absorbed by the chip and it transmits an audio frequency signal that contains an identification code that matches up to the unique digital serial number in the car key programmer's computer system. This stops unauthorised attempts to start the car as only the correct keys will be able.

This type of technology is thought to be more secure than a conventional car key since it makes it harder for a thief "hot wire" the vehicle and then start it.
