Car Key Cutting Explained

cutting key the car key is more than just bending a piece of metal. It is a complicated procedure that ensures security, efficiency 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 that you can always drive your vehicle, you will need to have a replacement key cut.

Transponder Keys

Transponder chips are likely be added to cars that were built within the past 20 years. These microchips are situated in the key's handle and transmit a signal to your vehicle's onboard computers when you turn the key. The computer on board scans the digital serial numbers in the chip and only allows the car to start if it is the right one. This prevents thieves from stealing your car because they'd have to be aware of the unique serial number.

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

Locksmiths who offer these services can make keys for cars with chips. Some car dealers, like AutoZone offer keys with chips. These stores have a large selection of keys, and can assist you in finding the best one for your vehicle.

Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is more difficult to pick, and they can only be duplicated with expensive laser key cutting machines or with specially designed software. This technology is more common in luxury vehicles, but it is now being used in many affordable models of automobiles as well.

Another kind of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys have a resistor that is black on the blade of the key. It can be programmed with one of 15 possible values to stop it from starting a vehicle that's not designed to. They are expensive and require a key programming machine, which is only available at a few locksmiths.

VATS Keys

Before transponder keys or cars with 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 confirm that the right key was used to start the car. The black VATS pellet located in the middle of the VATS key isn't an electronic chip like the ones used in modern smart keys, it is simply a block of carbon appropriately sized to have an electrical resistance that is specific to.

GM used 15 different resistance values for VATS pellets and attached the key's blade to ensure that, when the key is turned in the ignition the coded signal is sent to the 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 will start to run. This doesn't make a vehicle safe from theft, but it will delay the thief by at minimum 15 to 20 minutes.

After a long period of use, the VATS module can start to wear out. Every time a key is inserted into the ignition it moves two very small wires within the ignition, and with time, the wires may begin to break. When enough wires have been broken the signal is lost to the module and the car won't start.

You can resolve this issue at home by decoding your VATS code. It's not hard to determine the resistance value of a key with the multimeter. You can determine the resistance value by putting one of the leads on the metal prongs on both sides of your key.

This is a great way to test out a new key and check whether it works in your car. Remove the ignition key first before you test it. In the event that it is not removed the key may have an incorrect VATS and will not work in your car.
