Car Key Cutting Explained Cutting a car key is more than just bending metal. It is a complicated process that guarantees security, function and long-term use of keys. It is not unusual to lose keys to your car, or have them break through the lock. To ensure you're able to always drive your vehicle, you will require a replacement key cut. Transponder Keys Transponder chips are likely be installed in cars that were built in the last 20 years. These microchips are situated in the key's handle and transmit a signal your vehicle's onboard computers when you use the key. The onboard computer reads the digital serial number inside the chip and allows the car to start if it is the right one. This stops thieves from taking over your vehicle because they'd have to be aware of the unique serial number. The microchip in the key transmits a low-level signal to the receiver within the car. The radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will only begin when it recognizes the code. This prevents the use of “hot wiring” and other methods of theft of cars. Car keys with chips can be created at a locksmith that offers these services. They are also available at a few automotive stores, such as AutoZone. Those stores carry a huge selection of keys and can assist you in selecting the best one for your vehicle. They can even help you program the chip to your vehicle, which is essential to make it work. There are also laser cut keys, which are more secure than flat keys. These keys are more secure than flat keys due to the fact that they have locks that are harder to pick. They are only duplicated with expensive laser key cutting machines or specialized software. This type of technology is typically found in luxury vehicles, but it is now being used in many affordable models of cars too. The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. The keys come with a resistor black on the blade of the key. It can be programmed with one of 15 possible values to prevent it from starting a vehicle that's not designed to. They are expensive and require an instrument for programming keys, which is only available through certain locksmiths. VATS Keys Before transponder keys or cars with computer chips that control the ignition, GM used a system 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 is not an electronic chip that is like those present on modern keys. It's just carbon or a block which is sized to hold an electrical resistance value. GM employed 15 different resistances for the VATS Pellets. They connected them to key blades in a way that, when the key is turned in the ignition a coded message is sent to module. If the signal matches the signal of the transistor in a VATS pellet, then the relay in starter circuit will turn on and the engine will begin to run. This does not make a car burglar-proof, but it can delay the thief for a minimum of 15 to 20 minutes. Unfortunately, after a long period of use, the VATS module in your car can start to wear out. The two wires that connect the ignition move each time the key is placed. 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. You can solve this problem at home by decoding your VATS key. You'll need a multimeter and an indicator chart to determine the resistance value of your key, but it is not difficult at all. All you have to do is put one of the leads of your ohm meter on the prongs of metal that are hanging out on both sides of the key, and then look at the display of the ohmmeter to determine the resistance of your key. This is a great method to test a new key and see whether it will work in your vehicle. Remove the ignition key first before you test it. Otherwise the key may have an incorrect VATS, and will not work in your car. Smart Key Fobs for Keys Key fobs today do more than simply unlock or start the vehicle.
