Car Key Cutting Explained Car key cutting is more than simply shaping a piece of metal. It is a complex process that guarantees security, functionality and the longevity of keys. It is not uncommon to lose your car key or even have it break in the lock. To ensure that you are able to always drive your car you'll require a replacement key cut. Transponder Keys Transponder chips are likely be fitted in vehicles built in the last 20 years. These microchips are located in the handle of the key and transmit a signal the onboard computers in your vehicle when you use the key. The computer on board detects the digital serial number in the chip and only allows the car to start if it's the correct one. This prevents thieves from hijacking your vehicle since they'd need to be aware of the unique serial number. The microchip inside your car key transmits a low-level radio signal to the car's receiver. This radio signal activates the microchip which then transmits code to the onboard computer of the car. The car will only start when it recognizes the code. This will stop the use of “hot wiring” and other methods of stealing cars. Car keys with chips can be made by locksmiths that offer these services. They can also be purchased at some automotive retailers like AutoZone. They have a huge range of keys and can assist you in finding the appropriate one for your vehicle. They can even assist you to programme the chip into your vehicle, which is essential to use it. There are also laser cut keys that are more secure than conventional flat keys. They are more secure than traditional flat keys because they have locks that are more difficult to pick. They are only duplicated with expensive laser key cutting equipment, or with specialized software. This type of technology is typically found in high-end cars, but it is now being used in a variety of affordable cars as well. The VATS (vehicle-anti-theft system) key is a different kind of key that is difficult to duplicate. These keys have a black resistor on the blade of the key that is programmed with one of 15 possible values to prevent them from starting a car that it's not intended to. These keys are more expensive to purchase and require a specific key programming device that can only be found at some locksmiths. VATS Keys Before transponder keys and cars with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a pellet of resistance embedded inside it to confirm that the correct key is being used to start the vehicle. The black VATS Pellet in the middle of a VATS Key is not a smart chip like those present on modern keys. It is merely carbon or a block which is sized to hold an electrical resistance value. GM employed 15 different resistance values for the VATS pellets and connected them to the blade of the key to ensure that, when the key is turned on the ignition, a coded signal is transmitted to the module. If the signal matches the one of the transistors in a VATS pellet then the relay in the starter circuit will turn on and the engine will begin to run. This doesn't make a vehicle safe from theft, but it will delay the theft by at least 15 to 20 minutes. Unfortunately, after a significant amount of usage, the VATS module in your car may begin to wear out. The two wires that connect the ignition are moved each time the key is inserted. As time passes the wires can begin to break. Once enough wires are broken the signal is lost to the module and the car will not start. Learn Alot more Here is that you can fix this issue yourself by decoding your VATS key. You'll require a multimeter and an indicator chart to determine the resistance value of your key, but it is not that difficult. You can determine the resistance value by putting one of the leads on the metal prongs on both sides of your key. This is also a great way to test a new key to see whether it works in your car. Just be sure to remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and not function in your car.

These are often employed in conjunction with remote-start hacks that allow thieves to access the settings of your vehicle by sending false signals from a nearby transmitter.
