The chip absorbs this energy, and then transmits a radio frequency signal that contains an identification code. This code is in line with the unique digital serial numbers that are stored in the computer system of the car. This stops unauthorised attempts to start the car, as only proper keys will be able to do so. The technology is believed to be more secure than a conventional car key, as it makes it more difficult for a thief hot wire the vehicle and start it.
