The energy is absorbed by the chip and sends back a radio frequency signal with an identification code that is matched with the unique digital serial number that is stored in the car's computer system. This prevents unauthorized attempts to start the car, since only the right key can start the car.
This technology is thought to be more secure than a traditional car key since it makes it harder for a criminal to "hot wire" the vehicle to start it.
