Transponder Keys If your car was manufactured in the past 20 years, it's likely that it has transponder chips. These microchips are tiny located in the handle of your key that transmit signals to the car's onboard computer whenever you use it. The computer on board scans the digital serial numbers within the chip and allows the car to start if it's the right one. This prevents car theft since thieves need to know your unique serial number in order to be able to steal it. The microchip inside your car key sends a low-level radio signal to the receiver inside the car. The radio signal activates your microchip which then transmits instructions to the onboard computer of the car. The car will be able to recognize this code and only allow it to start if it is the correct one. This will stop the use of “hot wiring” and other methods of taking cars.

The VATS black pellet that is inside the middle of a VATS key is not an electronic chip as found on modern smart keys, it is simply a block of carbon appropriately sized to have a specific electrical resistance value. GM employed 15 different resistances for the VATS Pellets. They connected them to key blades so that, when the key was turned on, a coded message is sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine begins to run.
