The computer on board reads the digital serial number within the chip and allows the car to start if it's the right one. This stops theft of vehicles as thieves would have to know your unique serial number in order to be able to steal it.

The microchip in the key transmits a low-level signal the car's receiver. The radio signal activates your microchip which then transmits code to the onboard computer of the car.
