The chip absorbs this energy and then transmits a radio frequency signal that contains an identification code. This code matches the unique serial numbers in the car's computers. This helps prevent unauthorized attempts to start the car, because only a valid key can start the car.

The technology is believed to be more secure than a traditional car key since it makes it harder for thieves to "hot wire" the vehicle and start it.
