The computer in the car checks the serial number digitally of the chip before allowing the car to begin. This stops thieves from stealing your car since they'd need to know the unique serial number.

The microchip inside the key sends a low-level signal the car's receiver. The radio signal activates your microchip, which transmits a code to the onboard computer of the car. The car will only begin only if it recognizes the code. This will stop the use of "hot wiring" and other methods of theft of cars.
