Car Key Cutting Explained

Cutting keys for cars is more than just bending metal. It is a complicated procedure that ensures safety, functionality and longevity of keys.

It is not uncommon to lose keys to your car or have them break through the lock. To ensure you're able to always drive your vehicle, you will need a new key cut.

Transponder Keys

If your car was manufactured within the last 20 years, it's likely that it has a transponder chip. These microchips are tiny in the handle of your key that transmit an electronic signal to the car's onboard computer whenever you use it. The computer on board detects the digital serial number inside the chip and allows the car to start if it's the correct one. This prevents car thieves from hijacking your vehicle 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. The radio signal activates the microchip, which transmits an informational code to the car's onboard computer. The car will be able to recognize the code and only allow it to start only if it is the correct one. This prevents the use of "hot wiring" and other methods of stealing cars.

Car keys with chips can be made at a locksmith that offers these services. They are also available at a few automotive stores, such as AutoZone. Those stores carry a huge variety of keys and can assist you in choosing the appropriate one for your car. They can help you program your car's chip, which is required to use the device.

Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is more difficult to pick, and they are only duplicated using expensive laser key cutting (navigate to these guys) machines or with specially designed software. This type of technology is typically 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 is difficult to duplicate. These keys feature a black resistor on the key blade that is programmed with one of fifteen possible values to prevent them from starting a vehicle that it's not intended to. These keys are more expensive to purchase and require a special key cutting key programming device that can only be 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 uses a key with a resistor embedded in it to verify that the correct key was used to start the car. The VATS black pellet that is in the center of the VATS key isn't an electronic chip like the ones found on modern smart keys, it's simply a block of carbon that is sized appropriately to have an exact electrical resistance.

GM used 15 different resistances for the VATS Pellets and attached the key blades to them so that when the key was turned in the ignition a coded message is sent to module. If the signal matches that of the transistor in a VATS pellet, then the relay in the starter circuit will turn on and the engine will start to run. This doesn't make a car secure from theft however it can delay the theft by at least 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 moves two very small wires inside the ignition, and over time the wires may begin to break. Once enough wires are broken the signal is lost to the module and the car won't start.

The good news is that you can fix this problem yourself at home by decoding your own VATS key. It's not difficult to determine the resistance value of a key by using a multimeter. All you need to do is place one of the leads of your ohm meter on the metal prongs that are visible on both sides of the key, and then read the ohm meter's display to determine the resistance of your key.

This is also a good way to test a new key to determine whether it will work in your car. Just 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 work in your car.
