Car Key Cutting Explained Car key cutting is more than just shaping the metal. It is a complicated procedure that guarantees security, function and longevity of keys. It is not unusual to lose your car key or have it break off in the lock. You'll require an alternative car key to ensure you can drive your vehicle at all times. Transponder Keys If your car was manufactured within the last 20 years, it's likely to have transponder chips. These chips are small microchips in the handle of your key that transmit signals to the car's onboard computer whenever you use it. The computer on board scans the digital serial numbers within the chip and allows the car to start if it's the correct one. This stops theft of vehicles since thieves need to know your unique serial number to have a chance at hijacking it. The microchip in the key transmits a low-level signal to the receiver within the car. This radio signal activates the microchip, and it then sends an encoded code to the car's onboard computer. The car will be able to recognize this code and will only allow it to start when the key is the correct one. This will stop “hot wiring” or other methods of stealing cars. Car keys with chips can be made at a locksmith that offers these services. Some car dealers, like AutoZone offer them. They have a huge range of keys and can help you find the appropriate one for your car. They can also help you programme the chip into your vehicle, which is required to use it. You can also get laser cut keys, which are more secure than flat keys. They are more secure than flat keys because they have a lock that is harder to pick. They can only be duplicated using expensive laser key cutting machines or with specialized software. This technology is most common in high-end cars however, it is now available in a wide range of low-cost models. The VATS (vehicle-anti-theft system) key is another type of key that's difficult to duplicate. These keys contain a resistor that's black on the blade of the key. It can be programmed to any of 15 possible values to stop it from starting a vehicle it's not intended to. These keys are more expensive to purchase and require a specific key programming device that can only be located at certain locksmiths. VATS Keys Before the advent of transponder keys and automobiles equipped with computer chips that control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key that has a resistor pellet embedded inside it to confirm that the correct key is used to start the vehicle. The VATS pellet that is black that is located in the middle of the VATS Key isn't a smart chip like those used on the majority of modern keys. It is merely carbon or a block that is sized to have an electrical resistance value. GM used 15 different resistance values for VATS pellets and connected them to the key's blade to ensure that, when the key is turned on the ignition, a coded signal is sent to the module. If the signal matches the one of the transistors in a VATS pellet then the relay in the starter circuit will be activated and the engine will start to run. This does not make a car secure from burglary however it could delay a thief for at least 15 to 20 minutes. Unfortunately, after a lot of use, the VATS module in your car can begin to wear out. The two wires that connect the ignition are moved every when the key is placed. As time passes, the wires may begin to break. When enough wires are broken, the signal to the module gets lost and it won't start the car. The good news is that you can solve this issue yourself by decoding your own VATS key. It's not difficult to determine the resistance of a key by using the multimeter. You can determine the resistance value by placing one of the leads on the prongs of metal on both sides of your key. This is also a great way to test a new key to determine if it will work in your car. Remove automotive key cutting before you test it. If not, the key may have an incorrect VATS, and will not work in your car. Smart Key Fobs Key fobs today are more than simply unlock and start the vehicle.
