Car Key Cutting Explained

Cutting the car key is more than just bending metal. It is a complicated procedure that guarantees security, function and longevity of keys.

It is not unusual to lose your car keys or have them break in the lock. To ensure that you can always drive your vehicle you'll need a new key cut.

Transponder Keys

If your car was built within the last 20 years, it's likely to have transponder chips. These microchips are located in the key's handle and transmit a signal your vehicle's onboard computers when you press the key. The computer on board detects the digital serial number inside the chip and allows the car to start if it's the right one. This stops theft of vehicles since thieves need to know your unique serial number to be able to take over it.

The microchip inside your car key sends an unintentional radio signal to the receiver inside the car. The radio signal activates the microchip, which transmits an encoded code to the car's onboard computer. The car will only start when it recognizes the code. This prevents "hot wiring" or other methods of stealing cars.

Locksmiths who offer these services can create keys for cars with chips. Some automotive retailers such as AutoZone sell keys with chips. Those stores carry a huge selection of keys and can assist you in selecting the best one for your car. They can even assist you to program the chip to your vehicle, which is required to use it.

laser car key cutting Service near me cut keys are more secure than flat keys. These keys have the lock cylinder, which is much harder to pick, and can only be duplicated with expensive laser key cutting equipment or specialized software. This type of technology is typically found in luxury cars but is now accessible on many affordable models.

The VATS (vehicle-anti-theft system), key is another type of key that is difficult to duplicate. The keys are black with a resistor on the blade of the key cutting business that is programmed with one of 15 possible values to stop them from starting a car that it's not designed to. These keys are expensive and require a key programming machine, which is only available at certain locksmiths.

VATS Keys

Before transponder keys or cars that had computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS makes use of a key with a resistor embedded in it to verify that the correct key was used to start the car. The black VATS Pellet in the middle of a VATS Key isn't a smart chip as found on most modern keys. It's just carbon or a block that is sized to provide an electrical resistance.

GM used 15 different resistance values for the VATS pellets and connected the key's blade so that when the key is turned on in the ignition, a coded signal 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 will start to run. This doesn't make a car secure from theft, but it will delay the thief by at most 15 to 20 minutes.

Unfortunately, after a long period of usage, the VATS module in your car can begin to wear out. The two wires inside the ignition are moved each time a key is placed. As time passes the wires can 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 solve this problem yourself at home by decoding your own VATS key. It's not difficult to determine the resistance of a mobile key cutting using the multimeter. All you need to do is place one of the leads of your ohm gauge on the prongs made of metal sticking out on both sides of the key, and then read the ohm meter's display to determine the resistance value of your key.

This is also a great way to test a new key to see if it will work in your car. Remove the ignition key first before you test it. Otherwise, the key may have an incorrect VATS and will not work in your vehicle.
