This prevents car theft, as thieves would need to know your unique serial number in order to have a chance at hijacking it.

The microchip in your car key transmits an low-level radio signal to the receiver inside the car. The radio signal activates the microchip, and it then sends an encoded code to the car's onboard computer. The car will only start only if it recognizes the code.
