Car Key Cutting Explained Car key cutting is much more than simply shaping a piece of metal. It is a complicated procedure that ensures security, efficiency, and longevity of the keys. It is not unusual to lose keys to your car, or even have them break into the lock. You will need an alternative car key to ensure that you are able to drive your vehicle at all times. Transponder Keys If your car was manufactured in the last 20 years, it's likely to have a transponder chip. These chips are tiny microchips located in the handle of your key that send signals to the car's onboard computer when you use it. The computer onboard examines the serial number of the chip before it allows the car to begin. This prevents car thieves from stealing your car since they'd need to be aware of the unique serial number. The microchip in your car key transmits a low-level radio signal to the car's receiver. The radio signal activates microchip, and it then sends an informational code to the car's onboard computer. The car will be able to recognize this code and only allow it to start if the key is the correct one. This will stop “hot wiring” or other methods of stealing cars. Locksmiths that offer these services can make keys for cars with chips. Some auto dealers like AutoZone sell keys with chips. They have a vast selection of keys and can assist you in selecting the best one for your vehicle. They can even help you programme the chip into your vehicle, which is essential to use it. You can also get laser cut keys, which are more secure than traditional flat keys. These keys have an cylinder for locking that is more difficult to pick, and can only be duplicated with expensive laser key cutting equipment or specially designed software. This technology is most commonly found in luxury 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. The keys are black with a resistor in the key blade that is programmed with one of 15 possible values to prevent the car from starting that it's not meant to. These keys are more expensive to buy and require a specific key programming machine that can only be found at some locksmiths. VATS Keys Before transponder keys and cars that had computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). locksmith key cutting uses an ordinary key with a pellet of resistance embedded within it to verify that the correct key is being used to start the car. The black VATS pellet located in the middle of the VATS key isn't a chip like those used in modern smart keys, it's simply a carbon block appropriately sized to have an electrical resistance that is specific to. GM used 15 different resistances for the VATS Pellets. They attached the key blades to them so that when the key was turned in the ignition the key blades transmit a coded message to the module. If the signal matches the signal of the transistor in a VATS pellet, then the relay in starter circuit will activate and the engine will begin to run. This doesn't make a car burglar-proof however it could delay a thief for at least 15 to twenty minutes. Unfortunately, after a significant amount of usage, the VATS module in your car may begin to wear out. Each time the key is inserted into the ignition, it moves two very small wires inside the ignition and with time, the wires could start to break. Once enough of the wires break, the signal to the module is lost and it won't start the car. You can solve this issue at home yourself by decoding your VATS key. It's not hard to determine the resistance value of a key by using a multimeter. You can find the resistance value by placing one of the leads on the metal prongs on both sides of your key. This method can also be a good method to test the new key to determine whether it will work in your vehicle. 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 may not function in your car.
