Transponder Keys

Transponder chips will likely be fitted in vehicles built within the past 20 years. These chips are tiny microchips located in the key's handle that transmit an electronic signal to the car's onboard computer whenever you use it. The computer in the car reads the digital serial number within the chip and allows the car to start if it's the correct one. This helps prevent theft of cars, as thieves would need to know your unique serial number to be able to steal it.

The microchip inside your car key transmits a low-level radio signal to the car's receiver. The radio signal activates the microchip, which transmits an encoded code to the car's onboard computer. The car will only begin only if it recognizes the code. This stops "hot wiring" or other methods to steal cars.

Locksmiths who offer these services can design keys for cars that contain chips. They are also available at certain automotive stores, such as AutoZone.

Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the key blade that is programmed with one of 15 possible values to stop them from starting a vehicle that it's not designed to. These keys are more expensive to purchase and require a special key programming device that can only be found at a few locksmiths.

The black VATS Pellet located in the middle of a VATS Key is not a smart chip like those used on the majority of modern keys. It is merely carbon or a block that is sized to provide an electrical resistance value.

GM used 15 different resistances for VATS pellets and attached them to key blades in a way that, when the key was turned on, a coded message is sent to the module. If it matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine will start to run. This doesn't make a car secure from theft however it will delay the thief by at minimum 15 to 20 minutes.

Unfortunately, after a significant amount of use, the VATS module in your car can begin to wear out.

When enough wires are broken the signal to the module is not received and it will not start the car.

The good news is that you can fix this problem yourself at home by decoding your own VATS key. You'll need a multimeter and a chart to find out the resistance value of your 24 hour key cutting, but it is not that difficult.
