These microchips are in the handle of the key and send a signal to the onboard computers in your vehicle when you press the key. The computer in the car is able to verify the digital serial number of the chip before allowing the car to begin. This stops thieves from stealing your car because they'd have to know the unique serial number. The microchip inside the key transmits a low-level signal the car's receiver. The radio signal activates microchip, and it then sends a code to the car's onboard computer. The car will be able to recognize the code and only allow it to start only if it is the correct one.
