Car Key Cutting ExplainedCar key cutting is much more than just shaping an object of metal. It is a complex process that guarantees security, function and long-term use of keys.
It is not unusual to lose keys to your car or even have them break into the lock. You'll need an alternative car key to ensure you can drive your car at all times.
Transponder Keys
If your car was manufactured in the last 20 years, it's likely that it has transponder chips. These chips are tiny microchips inside the key's handle which transmit 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 is the right one. This helps prevent theft of cars 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. This radio signal activates the microchip that then transmits the code to the computer onboard of the car. The car will only start if it recognizes this code. This will stop the use of "hot wiring" and other methods of taking cars.
Car keys with chips can be created at an authorized locksmith who offers these services. They can also be purchased at certain automotive stores like AutoZone. Those stores carry a huge variety of keys and can help you get the right one for your vehicle. They can help you program your vehicle's chip, which is required to operate the device.

Another kind of car key that is difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor in the emergency key cutting blade that is programmed with one of 15 potential values to prevent the car from starting that it's not intended to. These keys are more expensive to purchase and require a special key cutter programming machine that can only be found at a few locksmiths.
VATS Keys
Before transponder keys or cars with computer chips built in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS makes use of a regular key that has a resistor pellet embedded inside it to confirm that the correct key is being used to start the car. The VATS pellet in black that is located in the middle of the VATS Key isn't a smart chip like those found on most modern keys. It's just carbon or a block that is sized to provide an electrical resistance.
GM employed 15 different resistance values for the VATS pellets and attached them to the blade of the key to ensure that, when the key is turned on the ignition the coded signal is sent to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in the starter circuit will activate and the engine will start to run. This doesn't make a vehicle theft proof however it will delay the thief by at least 15 to 20 minutes.
Unfortunately, after a long period of use, the VATS module in your car can begin to wear out. The two wires inside the ignition are moved each time the key is inserted. Over time, the wires may begin to break. Once enough wires are broken the signal is lost to the module and the car won't begin.
You can solve this issue at home by decoding your VATS code. It's not hard to determine the resistance of a key using the multimeter. All you have to do is put one of the leads of your ohm meter onto the prongs of metal that are hanging out on both sides of the key, then look at the display of the ohmmeter to determine the resistance of your key.
This method can also be a good method to test a new key to see if it will work in your vehicle. Remove the ignition key first before you test it. In the event that it is not removed the key could have an incorrect VATS, and will not work in your vehicle.
