The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched up to the unique serial number in the car's computer system. This will prevent any unauthorised attempts to start the car because only a valid key will be able to start the car.
This type of technology is thought to be more secure than a traditional car key, as it makes it difficult for a thief "hot wire" the vehicle to start it.
