Car Key Cutting Explained

Car key cutting is much more than simply shaping an object of metal. It is a complex process that guarantees security, function and long-term use of keys.

It is not unusual to lose your car keys or even have it break in the lock. To ensure that you are able to always drive your car, you will require a replacement key cut.

Transponder Keys

If your car was manufactured in the past 20 years, it is likely that it has a transponder chip. These chips are small microchips located in the key's handle that transmit an electronic signal to the car's onboard computer when you use it. The computer onboard examines the serial number digitally of the chip before giving the car permission to begin. This stops theft of vehicles as thieves would have to know your unique serial number in order to have a chance at hijacking it.

The microchip inside the key sends a low-level signal the receiver within the car. The radio signal activates the microchip, and it then sends an encoded code to the car's onboard computer. The car will only start when it recognizes the code. This prevents the use of "hot wiring" and other methods of taking cars.

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

Laser cut keys are more secure than flat keys. They have an cylinder for locking that is more difficult to pick, and can only be duplicated using expensive laser key cutting (Sciencewiki.science) machines or with specialized software. This type of technology is typically found in high-end cars, but it is now available in many affordable models of cars as well.

Another type of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the blade of the key that is programmed with one of 15 potential values to prevent them from starting a car that it's not designed to. These keys are costly and require an instrument for programming keys, which is only available through 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 an ordinary key with a pellet of resistance embedded within it to verify that the correct key is used to start the car. The black VATS Pellet in the middle of a VATS Key is not a smart chip as present on modern keys. It is simply carbon or a block that is sized to have an electrical resistance value.

GM used 15 different resistances for the VATS Pellets and attached the key blades to them so that when the key is turned in the ignition a coded message is sent to the module. If the signal is in line with 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 car secure from burglary however, it can deter thieves for at least 15 to 20 minutes.

Unfortunately, after a lot of use, the VATS module in your car may start 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 could start to break. When enough wires have been broken, the signal is lost to the module and the car will not start.

The good news is that you can solve this problem yourself at home by decoding your VATS key. It's not hard to determine the resistance value of a key with the multimeter. All you need to do is place one of the leads of your ohm meter onto the prongs of metal that are hanging out on both sides of the key, then examine the display of your ohm meter to find out the resistance value of your key.

This is a great opportunity to test a new key and check whether it works in your car. Be sure to remove the key from the ignition before you begin testing it, or else the new key may have an incorrect VATS value and not function in your car.
