This helps prevent theft of cars as thieves would have to know your unique serial number to be able to steal it. The microchip inside your car key sends a low-level radio signal to the car's receiver. This radio signal activates the microchip, and it then sends an informational code to the car's onboard computer. The car will only start if it recognizes this code.

The VATS pellet black located in the middle of a VATS key is not an electronic chip like the ones used in modern smart keys, it is simply a piece of carbon that is sized appropriately to have an electrical resistance that is specific to. GM employed 15 different resistance values for the VATS pellets. They attached them to the blade of the key, so that when the key is turned in the ignition a coded signal will be sent to the module.
