These microchips are in the handle of the key cutting cost and transmit a signal to your vehicle's onboard computers when you turn the key. The onboard computer examines the serial number of the chip before allowing the car to start. This prevents car thieves from taking over your vehicle, as they would need to know the unique serial number.

The microchip inside the key cutting cost sends a low-level signal the receiver within the car. This radio signal activates the microchip, which transmits a code to the car's onboard computer. The car will recognize the code and only allow it to start if it is the correct one. This prevents "hot wiring" or other methods of stealing cars.
