Car Key Cutting Explained

Cutting a car key is more than just bending a piece of metal. It is a complex procedure that ensures security, efficiency and long-term use of the keys.

It is not uncommon to lose your car key or have it break off in the lock. To ensure that you can always drive your vehicle, you will need a new key cut.

Transponder Keys

Transponder chips will likely be added to cars that were built within the past 20 years. These microchips are in the handle of the key and send a signal to the onboard computers in your vehicle when you press the key. The computer in the car scans the digital serial numbers in the chip and only allows the car to start if it's the correct one. This prevents car theft as thieves would have to know your unique serial number in order to be able to take over it.

The microchip inside your car keys transmits an low-level radio signal to the car's receiver. The radio signal activates your microchip that then transmits the code to the computer onboard of the car. The car will only start if it recognizes this code. This prevents 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. Some car dealers, like AutoZone sell them. They have a huge selection of keys, and can assist you in finding the best one for your vehicle. They can even assist you to program the chip to your vehicle, laser key cutting which is essential to make it work.

You can also purchase laser cut keys that are more secure than flat keys. These keys have a lock cylinder that is more difficult to pick, and can only be duplicated using expensive laser key cutting machines or with special software. This technology is most commonly found in high-end cars, but is now available in a wide range of low-cost models.

Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) local key cutting. These keys contain a resistor that's black on the blade of the key. It can be programmed to any of a variety of values to prevent it from starting a vehicle it's not intended to. They are expensive and require a key programming machine, which is only available at a few locksmiths.

Keys to VATS

Before transponder keys or vehicles with computer chips that control the ignition, GM used a system called 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 used to start the vehicle. The black VATS Pellet that is located in the middle of the VATS Key isn't an electronic chip that is like those present on modern keys. It is merely a block or carbon that is sized to provide an electrical resistance value.

GM employed 15 different resistance values for the VATS pellets. They attached them to the key's blade, so that when the key is turned on the ignition a coded signal will be transmitted to the module. If it matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine starts to run. This doesn't make a vehicle secure from theft however it will delay the thief by at most 15 to 20 minutes.

After a long period of use the VATS module could begin to wear out. Each time the key is inserted into the ignition it moves two very small wires inside the ignition, and, over time, the wires may start to break. Once enough wires are broken, the signal is lost to the module and the car won't start.

You can solve this problem at home by decoding your VATS code. You'll require a multimeter as well as a chart to determine the resistance value of your key, but it is not that difficult. All you have to do is put one of the leads of your ohm meter onto the prongs made of metal hanging out on both sides of the key. Then examine the display of your ohm meter to determine the resistance of your van key cutting.

This is a great method to test out a new key and check if it works in your car. Just be sure to remove the key from the ignition prior to testing it, or else the new key may have an incorrect VATS value and may not work in your vehicle.
