Car Key Cutting Explained Car key cutting is more than just shaping an object of metal. It is a complicated process that guarantees security, function and long-term use of keys. It is not uncommon to lose your car key or even break it in the lock. To ensure that you can always drive your vehicle you'll need to have a replacement key cut. Transponder Keys If your car was built within the last 20 years, it is likely to have a transponder chip. These chips are small microchips inside the handle of your key which transmit an electronic signal to the car's onboard computer whenever you use it. The computer in the car detects the digital serial number inside the chip and allows the car to start if it is the right one. This prevents thieves from stealing your car, as they would need to be aware of the unique serial number. The microchip inside your car key transmits a low-level radio signal to the receiver inside the car. The radio signal activates the microchip, which then transmits an informational 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 created at locksmiths that offer these services. Some automotive retailers such as AutoZone offer them. Those stores carry a huge selection of keys and can help you get the right one for your vehicle. They can help you program your vehicle's chip that is required for the device to function. Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys because they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting machines or with specialized software. This technology is more prevalent in high-end vehicles, however it is now accessible in a variety of affordable cars too. The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. These keys come with a resistor black on the blade of the key. It can be programmed to one of a variety of values to stop it from starting a vehicle that's not designed to. These keys are more expensive to purchase and require a specific key programming machine that is only found at a few locksmiths. VATS Keys Before transponder keys or vehicles with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a pellet of resistance embedded inside it to confirm that the correct key is used to start the vehicle. The VATS pellet black inside the middle of the VATS key isn't a chip like those found on modern smart keys. It is simply a piece of carbon properly sized to carry an exact electrical resistance. GM used 15 different resistance values for the VATS pellets. They connected the key's blade, so that when the key is turned on in the ignition the coded signal is sent to the module. If the signal matches the one of the transistors 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 theft proof however it will delay the theft by at most 15 to 20 minutes. Unfortunately, after a long period of use the VATS module in your car may start to wear out. Each time a key is inserted into the ignition it reroutes two small wires inside the ignition and, over time, the wires can start to break. When enough wires have been broken the signal goes out to the module and the car won't start. laser key cutting near me can solve this problem at home yourself by decoding your VATS code. It's not hard to determine the resistance value of a key by using the multimeter. All you need to do is put one of the leads of your ohm gauge on the prongs made of metal visible on both sides of the key, and then examine the display of your ohm meter to find out the resistance of your key. This method is also a good way to test a new key to see whether it will work in your car. Be sure to remove the key from the ignition before you begin testing it, or else the new key could be displaying an incorrect VATS number and will not work in your car.
