Car Key Cutting Explained

Cutting a car key is more than just bending 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. To ensure you're able to always drive your vehicle, you will require a replacement key cut.

Transponder Keys

If your car was manufactured within the last 20 years, it's likely that it has a transponder chip. These chips are tiny microchips located in the handle of your key that transmit signals to the car's onboard computer when you are using it. The computer on board reads the digital serial number in the chip and only allows the car to start if it is the right one. This prevents car theft, as thieves would need to know your unique serial number in order to be able to take over it.

The microchip in your car key transmits an unintentional radio signal to the receiver inside the car. This radio signal activates the microchip that then transmits the code to the onboard computer of the car. The car will only begin when it recognizes the code. This prevents "hot wiring" or other methods to steal cars.

Locksmiths who offer these services can create keys for cars with chips. They can also be bought at a few automotive stores like AutoZone. Those stores carry a huge variety of keys and can help you get the right one for your car. They can assist you in programming the chip in your vehicle which is needed to use the device.

The VATS (vehicle-anti-theft system) key is another type of key that's difficult to duplicate. The keys have a resistor that is black on the blade of the key cutting open now. It can be programmed to one of 15 possible values to prevent it from starting a car that's not intended to. These keys are more expensive to purchase and require a specific key programming device that can only be found at some locksmiths.

Keys to VATS

Before the advent of transponder keys as well as cars with built-in computer chips to control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has a resistor embedded in it to verify that the correct key was used to start the car. The VATS pellet that is black in the middle of a VATS Key isn't a smart chip as present on modern keys. It is merely carbon or a block which is sized to have an electrical resistance.

GM used 15 different resistance values for VATS pellets and attached them to the blade of the key so that when the key is turned on in the ignition the coded signal is transmitted to the module. If the signal matches that of the transistor in a VATS pellet then the relay in starter circuit will activate and the engine will begin to run. This doesn't make a vehicle secure from theft, but it will delay the theft by at least 15 to 20 minutes.

After a long period of use the VATS module may begin to wear out. Every time a key is inserted into the ignition, it moves two tiny wires within the ignition, and over time the wires can begin to break. If enough wires are damaged the signal goes out to the module and the car won't begin.

The good news is that you can fix this issue at home by decoding your VATS key. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it's not that difficult. You can find the resistance value by placing one of the leads on the metal prongs on both sides of your key.

This is also a great way to test a new key to see whether 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 function in your vehicle.
