If your car was built in the last 20 years, it's likely to have a transponder chip. These chips are small microchips inside the handle of your key that send an electronic signal to the car's onboard computer when you use it. The computer in the car scans the digital serial numbers in the chip and only allows the car to start if it's the right one. This prevents car theft, as thieves would need to know your unique serial number to be able to steal it.

The microchip inside the key transmits a low-level signal the receiver within the car. This radio signal activates your microchip that then transmits the code to the onboard computer of the car. The car will be able to recognize this code and will only allow it to start only if it is the correct one. This stops the use of "hot wiring" and other methods of stealing cars.

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