Car Key Cutting Explained

Car key cutting is much more than just forming an object of metal. It is a sophisticated procedure that ensures security, efficiency and long-term use of the keys.

It is not unusual to lose keys to your car or have them break in the lock. You will need a replacement car key to ensure that you can drive your vehicle at all times.

Transponder Keys

If your car was manufactured in the past 20 years, it is likely to have a transponder chip. These microchips are tiny in the key's handle that send a signal to the vehicle's onboard computer when you use it. The computer in the car 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 to be able to take over it.

The microchip inside the key transmits a low-level signal to the car's receiver. This radio signal activates the microchip, which transmits a code to the computer onboard of the car key cut. The car will only start only if it recognizes the code. This prevents "hot wiring" or other methods of stealing cars.

Car keys with chips can be made at locksmiths that offer these services. Some auto key cutting machine dealers like AutoZone offer keys with chips. They have a vast range of keys and will assist you in choosing the appropriate one for your car. They can help you program your vehicle's chip which is needed to use the device.

This type of technology is typically found in luxury cars, but is now available in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) key is a different type of key that is difficult to duplicate. The keys are black with a resistor on the blade of the key that is programmed with one of 15 possible values to stop them from starting a car that it's not meant to. These keys are more expensive to buy and require a specific key programming machine that is only located at certain locksmiths.

VATS Keys

Before transponder keys and cars with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses a key with an internal resistor to ensure that the correct key was used to start the car. The VATS black pellet that is located in the middle of the VATS key isn't an electronic chip like the ones found on modern smart keys, it's simply a block of carbon appropriately sized to have an electrical resistance that is specific to.

GM employed 15 different resistance values for the VATS pellets. They connected them to the key's blade to ensure that, when the key is turned on the ignition, a coded signal is sent to the module. If the signal matches 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 isn't a way to make a car safe from theft, but it will delay the thief by at least 15 to 20 minutes.

Unfortunately, after a lot of usage, the VATS module in your car could start to wear out. Each time the key is inserted into the ignition, it moves two tiny wires within the ignition, and over time the wires can start to break. When enough wires are broken the signal to the module is lost and the module won't be able to start the car.

The good news is that you can fix this issue at home by decoding your VATS key. You'll need a multimeter and 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 prongs of metal on both sides of your key.

This method is also a great way to test a new key to determine if 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 not work in your car.
