Car Key Cutting Explained

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

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

Transponder Keys

If your car was built in the last 20 years, it's likely to have transponder chips. These microchips are in the key's handle and transmit a signal to the onboard computers of your vehicle when you turn the key. The computer onboard is able to verify the serial number digitally of the chip prior to giving the car permission to begin. This prevents thieves from hijacking your vehicle, as they would need to know the unique serial number.

The microchip inside your car key sends an unintentional radio signal to the receiver inside the car. The radio signal activates your microchip that then transmits the instructions to the onboard computer of the car. The car will only start only if it recognizes the code. This stops the use of "hot wiring" and other methods of stealing cars.

Locksmiths that offer these services can make keys for cars with chips. They can also be purchased at certain automotive stores, such as AutoZone. These stores have a large variety of keys, and can assist you in finding the appropriate one for your car key cutting and programming. They can assist you in programming your vehicle's chip which is needed to operate the device.

Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is much more difficult to pick, and they can only be duplicated using expensive laser key cutting equipment or specialized software. This type of technology is typically found in high-end cars, but is now available on a variety of affordable models.

Another kind of car key that's difficult to duplicate is the VATS (vehicle anti-theft system) key. They come with a resistor black on the blade of the key. It can be programmed to any of 15 possible values to stop it from starting a car that's not designed to. These keys are more expensive to buy and require a special key programming machine that is only found at some locksmiths.

VATS Keys

Before the days of transponder keys as well as cars equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an internal resistor to confirm that the right key was used to start the car. The VATS pellet that is black that is located in the middle of the VATS Key is not a smart chip like those present on modern keys. It is simply a block or carbon that is sized to have an electrical resistance.

GM employed 15 different resistances for the VATS Pellets and attached them to key blades in a way that, when the key was turned in the ignition the key blades transmit a coded message to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in starter circuit will be activated and the engine will begin to run. This doesn't make a car theft proof, but it will delay the theft by at minimum 15 to 20 minutes.

Unfortunately, after a long period of use the VATS module in your car can begin to wear out. Every time a key is inserted into the ignition it reroutes two small wires inside the ignition, and, over time, the wires could start to break. Once enough wires are broken, the signal is lost to the module and the car will not start.

The good news is that you can fix this issue yourself by decoding your own VATS key. It's not difficult to determine the resistance of a key by using a multimeter. You can determine the resistance value by placing one of the leads on the prongs of metal on both sides of your key.

This is a great way to test a brand 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 will not work in your car.
