The onboard computer detects the digital serial number within the chip and allows the car to start if it is the right one. This stops theft of vehicles as thieves would have to know your unique serial number to have a chance at hijacking it.

The microchip in the key transmits a low-level signal the receiver within the car. This radio signal activates the microchip, which transmits a code to the onboard computer of the car.

GM used 15 different resistance values for the VATS pellets and connected the key's blade so that when the key is turned on the ignition, a coded signal is sent to the module.
