Car Key Cutting Explained

Car key cutting is more than just forming a piece of metal. It is a complex process that guarantees security, function and long-term use of keys.

It is not uncommon to lose your car keys or even break it in the lock. You'll need a replacement car key to ensure you can drive your car at all times.

Transponder Keys

If your car was built within the last 20 years, it is likely that it has a transponder chip. These chips are small microchips inside the handle of your key that send signals to the car's onboard computer when you are using it. The computer in the car checks the digital serial number of the chip prior to giving the car permission to begin. This prevents thieves from hijacking your vehicle because they'd have to be aware of the unique serial number.

The microchip in your car keys transmits a low-level radio signal to the receiver inside the car. The radio signal activates your microchip which then transmits code to the onboard computer of the car. The car will only start when it recognizes the code. This will stop "hot wiring" or other methods of stealing cars.

Locksmiths that offer these services can create keys for cars that contain chips. Some automotive retailers such as AutoZone sell them.

The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. The keys come with a resistor black on the blade of the key. It can be programmed to one of a variety of values to prevent it from starting a vehicle it's not intended to. These keys are more expensive to buy and require a special key programming device that can only be found at some 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 uses an ordinary key that has a resistor pellet embedded in it to confirm that the correct key is being used to start the car. The black VATS Pellet in the middle of a VATS Key is not a smart chip like those present on modern keys. It is merely carbon or a block that is sized to hold an electrical resistance.

GM used 15 different resistance values for VATS pellets and attached the key's blade so that when the key is turned in the ignition, a coded signal is sent to the module. If the signal is in line with the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine begins to run. This doesn't make a car secure from burglary however it could delay thieves for at least fifteen to twenty minutes.

After a lot of usage the VATS module may start to wear out. The two wires inside the ignition are moved each when the key is placed. As time passes the wires could begin to break. Once enough of the wires are broken, the signal to the module is lost and it won't start the car.

You can solve this problem at home by decoding your VATS code. It's not hard to determine the resistance of a key with a multimeter. All you need to do is place one of the leads of your ohm gauge on the prongs of metal that are sticking out on both sides of the key. Then look at the display of the ohmmeter to determine the resistance of your key.

This method is also a good way to test a new key to see whether it will work in your vehicle. Remove the ignition key first before you test it. If not the key could have an incorrect VATS and will not work in your car.

One way to protect the key fob's RFID is to store it in a metal case or a dedicated RFID blocking case that blocks the transmission of these signals. However, the necessity of removing the key fob from its case that is protected each time you want to use it undermines the convenience of the technology.
