Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece of metal. It is a complicated process that ensures safety, functionality and long-term use of keys.

Transponder Keys

Transponder chips are likely to be added to cars that were built within the past 20 years. These microchips are located in the key's handle and transmit a signal to the onboard computers of 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 right one. This prevents car thieves from stealing your car because they'd have to know the unique serial number.

The microchip inside the key transmits a low-level signal the car's receiver. The radio signal activates the microchip, which transmits a code to the car's onboard computer. The car will only start when it recognizes the code. This stops the use of "hot wiring" and other methods of theft of cars.

Locksmiths who offer these services can create keys for cars with chips. Some auto dealers like AutoZone sell them.

They are expensive and require a key programming machine, which is only available at a few locksmiths.

VATS Keys

Before the advent of transponder keys and automobiles with built-in computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an embedded resistor to ensure that the correct key was used to start the car. The VATS pellet in black in the middle of a VATS Key isn't an electronic chip that is like those present on modern keys. It is merely carbon or a block which is sized to have an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets and connected the key's blade, so that when the key is turned in the ignition a coded signal will be sent to the module. If the signal matches 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 does not make a car burglar-proof, but it can delay the thief for a minimum of 15 to twenty minutes.

Unfortunately, after a significant amount of use the VATS module in your car can begin to wear out. The two wires inside the ignition are moved each when the key is inserted. As time passes the wires could begin to break. Once enough wires are broken the signal to the module gets lost and it won't start the car.

You can solve this problem at home yourself by decoding your VATS code. You'll require a multimeter and an indicator chart to determine the resistance value of your key, but it is not that difficult. You can find the resistance value by putting one of the leads on the prongs made of metal on both sides of your key.

This is a great opportunity to test a new key and see if it works in your vehicle. Remove the key from the ignition first before you test it. Otherwise, the key may have an incorrect VATS and not work in your vehicle.
