Seven Reasons Why Cut Car Key Is Important Car Key Cutting Explained Car key cutting is a lot more than just shaping an object of metal. It is a complicated process that ensures security, functionality and durability of keys. It is not unusual to lose your car key or even have it break in the lock. You'll need a replacement car key to ensure you can drive your car at all times. Transponder Keys Transponder chips will likely be fitted in vehicles built within the past 20 years. These microchips are situated in the handle of the key and transmit a signal to your vehicle's onboard computers when you turn the key. The onboard computer scans the digital serial numbers in the chip and only allows the car to start if it's the right one. This stops theft of vehicles, as thieves would need to know your unique serial number in order to be able to steal it. The microchip inside your car key sends an low-level radio signal to the receiver inside the car. The radio signal activates your microchip, which transmits a code to the onboard computer of the car. The car will recognize the code and only allow it to start when the key is the right one. This stops the use of "hot wiring" and other methods of theft of cars. Locksmiths who provide these services can design keys for cars that contain chips. Some auto dealers like AutoZone offer keys with chips. Those stores carry a huge range of keys and will assist you in selecting the best one for your vehicle. They can even help you program the chip to your vehicle, which is necessary for it to function. Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is more difficult to pick, and are only duplicated using expensive laser key cutting equipment or specially designed software. This technology is most commonly found in high-end cars however, it is now available on many affordable models. The VATS (vehicle-anti-theft system), key is another type of key that is difficult to duplicate. They have a resistor that is black on the blade of the key. It can be programmed to any of fifteen possible values to prevent it from starting a car that's not intended to. These keys are expensive and require the use of a key programming machine which is only available at certain locksmiths. VATS Keys Before transponder keys or vehicles with computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to ensure that the correct key was used to start the car. The black VATS pellet inside the middle of the VATS key isn't an electronic chip as used in modern smart keys, it is simply a block of carbon that is sized appropriately to have an exact electrical resistance. GM used 15 different resistance values for the VATS pellets. They attached the key's blade to ensure that, when the key is turned in the ignition, a coded signal is transmitted to the module. If the signal matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine starts to run. This does not make a car safe from burglary however, it can deter a thief for at least 15 to 20 minutes. Unfortunately, after a long period of usage, the VATS module in your car may start to wear out. The two wires inside the ignition are moved each time the key is inserted. As time passes, the wires may begin to break. Once enough of the wires break the signal to the module is lost and the module won't be able to start the car. The good news is that you can fix this problem yourself at home by decoding your own VATS key. It's not difficult to determine the resistance value of a key with a multimeter. over at this website can find the resistance value by putting one of the leads on the prongs of metal on both sides of your key. This method can also be a good method to test a new key to determine whether it works in your vehicle. Remove the key from the ignition first before you test it. If not, the key may have an incorrect VATS, and will not work in your car. Smart Key Fobs with Smart Keys Key fobs today can do more than just unlock or start the car.
