Car Key Cutting Explained Cutting the car key is more than just bending a piece of metal. It is a sophisticated process that guarantees security, functionality, and longevity of the keys. It is not uncommon to lose your car keys or even break it in the lock. To ensure that you can always drive your vehicle, you will require a replacement key cut. Transponder Keys Transponder chips are likely be fitted in vehicles built in the last 20 years. These microchips are situated in the key's handle and transmit a signal the onboard computers of your vehicle when you turn the key. The computer in the car examines the serial number digitally of the chip before giving the car permission to start. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to take over it. The microchip in your car keys transmits an unintentional radio signal to the receiver inside the car. This radio signal activates the microchip, which transmits a code to the car's onboard computer. The car will only begin only if it recognizes the code. This prevents the use of “hot wiring” and other methods of stealing cars. Car keys with chips can be created at locksmiths that offer these services. Some car dealers, like AutoZone sell keys with chips. These stores have a wide range of keys and will assist you in selecting the best one for your vehicle. They can even assist you to program the chip to your vehicle, which is necessary to use it. There are also laser cut keys, which are more secure than conventional flat keys. These keys 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 specialized software. This technology is more common in high-end cars, but it is now being used in a wide range of low-cost cars as well. The VATS (vehicle-anti-theft system) key is another kind of key that is difficult to duplicate. The keys are black with a resistor on the blade of the key that is programmed with one of 15 possible values to prevent them from starting a vehicle that it's not designed to. These keys are expensive and require an instrument for programming keys, which is only available at certain locksmiths. Keys to VATS Before the advent of transponder keys as well as cars equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses a key with a resistor embedded in it to confirm that the right key was used to start the car. The black VATS Pellet in the middle of a VATS Key isn't a smart chip like those used on the majority of modern keys. It is simply a block or carbon that is sized to provide an electrical resistance. GM employed 15 different resistances for the VATS Pellets. They connected them to key blades so that when the key is turned on, a coded signal is sent to module. If the signal is in line with the signal of the transistor in a VATS pellet, then the relay in the starter circuit will activate and the engine will start to run. This doesn't make a car secure from burglary however, it can deter the thief for a minimum of 15 to twenty minutes. After a lot of usage the VATS module may start to wear out. Each time a key is inserted into the ignition it moves two tiny wires inside the ignition, and with time, the wires can start to break. When enough 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 solve this issue at home by decoding your own VATS key. It's not difficult to determine the resistance of a key with the multimeter. You can find the resistance value by putting one of the leads on the prongs of metal on both sides of your key. This is a great method to test a new key and check whether it works in your vehicle. Remove the key from the ignition first before you test it. Otherwise the key could have an incorrect VATS and not work in your car. Smart Key Fobs for Keys Key fobs today can do more than simply unlock and start the vehicle.
