Transponder Keys
Transponder chips are likely be fitted in vehicles built in the last 20 years. These microchips are situated in the handle of the key and transmit a signal to the onboard computers in your vehicle when you press the key. The computer in the car scans the digital serial numbers within the chip and allows the car to start if it is the correct one. This stops theft of vehicles as thieves would have to know your unique serial number to be able to steal it.
The microchip inside your car key sends an unintentional radio signal to the receiver inside the car. This radio signal activates the microchip, which transmits a code to the computer onboard of the car. The car will only begin when it recognizes the code.

Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the blade of the key that is programmed with one of 15 potential values to prevent them from starting a car that it's not meant to.

Keys to VATS
Before the advent of transponder keys as well as cars with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System).

The VATS pellet that is black that is located in the middle of the VATS Key isn't an electronic chip that is like those found on most modern keys. It is merely carbon or a block that is sized to hold an electrical resistance.
GM employed 15 different resistance values for VATS pellets and connected them to the blade of the key so that when the key is turned on in the ignition a coded signal will be sent to the module. If the signal is in line with the signal of the transistor in a VATS pellet then the relay in the starter circuit will activate and the engine will begin to run. This doesn't make a car secure from theft however it can delay the theft by at most 15 to 20 minutes.
After a prolonged period of usage, the VATS module can begin to wear out. Each time the key is inserted into the ignition it moves two tiny wires within the ignition, and over time the wires can start to break. If enough wires are damaged the signal goes out to the module and the car won't begin.
You can solve this problem at home yourself by decoding your VATS code. You'll need a multimeter and a chart to find out the resistance value of your key, but it's not that difficult. All you need to do is place one of the leads of your ohm meter on the metal prongs that are hanging out on both sides of the key. Then look at cut key for car of the ohmmeter to find out the resistance value of your key.
