Car Key Cutting Explained
Car key cutting is more than just forming the metal. It is a complicated process that guarantees safety, functionality and long-term use of the keys.
It is not unusual to lose your car keys or have them break through the lock. To ensure you're able to always drive your car, you will need a new key cut.
Transponder Keys
Transponder chips are likely be added to cars that were that were built in the last 20 years. These chips are tiny microchips inside the key's handle which transmit signals to the car's onboard computer whenever you use it. The computer onboard examines the serial number of the chip before giving the car permission to begin. This prevents car thieves from stealing your car because they'd have to be aware of the unique serial number.
The microchip in the key transmits a low-level signal to the car's receiver. This radio signal activates the microchip, which then transmits a code to the car's onboard computer. The car will recognize the code and only allow it to start when the key is the correct one. This prevents "hot wiring" or other methods of stealing cars.
Car keys with chips can be made at a locksmith that offers these services. They can also be purchased at certain automotive stores, such as AutoZone. They have a huge selection of keys, and can help you find the best one for your car. They can also help you programme the chip into your vehicle, which is required for it to function.
Laser cut keys are more secure than flat keys. They have a lock cylinder that is much more difficult to pick, and can only be duplicated with expensive laser key cutting equipment or special software. This technology is most commonly found in high-end cars however, it is now available on a variety of affordable models.
The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of 15 possible values to stop them from starting a vehicle that it's not designed to. These keys are expensive and require an instrument for programming keys, which is only available through certain locksmiths.
VATS Keys
Before the advent of transponder keys and automobiles with built-in computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to ensure that the correct key was used to start the car. The black VATS pellet located in the middle of the VATS key isn't a chip like those present in modern smart keys, it is simply a carbon block appropriately sized to have an exact electrical resistance.
GM employed 15 different resistances for the VATS Pellets and connected them to key blades so that, when the key is turned on, a coded message is sent to 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 begins to run. This does not make a car burglar-proof, but it can delay thieves for at least fifteen to twenty minutes.
Unfortunately, after a significant amount of use, the VATS module in your car can start to wear out. Each time the key is inserted into the ignition, it moves two tiny wires inside the ignition, and with time, the wires can start to break. Once enough wires are broken the signal goes out to the module and the car will not start.
You can resolve this issue at home by decoding your VATS key. It's not difficult to determine the resistance of a key with a multimeter. All you need to do is place one of the leads of your ohm gauge on the metal prongs that are sticking out on both sides of the key, then examine the display of your ohm meter to find out the resistance of your key.
This is a great opportunity to test a brand new key and determine whether it will work in your car. Make sure you remove the key from the ignition prior to testing it, otherwise the new key could have an incorrect VATS value and may not function in your car.
