Car Key Cutting Explained Car key cutting is a lot more than simply shaping an object of metal. It is a complex process that ensures safety, functionality and longevity of keys. It is not uncommon to lose your car key or even break it in the lock. You'll require a new car key in order to ensure that you can drive your car at all times. Transponder Keys If your car was constructed in the last 20 years, it is likely to have transponder chips. These microchips are in the key's handle and transmit a signal to your vehicle's onboard computers when you use the key. The computer in the car examines the serial number digitally of the chip prior to allowing the car to begin. This prevents car theft as thieves would have to know your unique serial number to be able to steal it. The microchip in your car keys transmits an low-level radio signal to the car's receiver. This radio signal activates the microchip that then transmits the code to the onboard computer of the car. The car will only begin if it recognizes this code. This will stop “hot wiring” or other methods of stealing cars. Car keys with chips can be made by a locksmith that offers these services. Some car dealers, like AutoZone offer keys with chips. They have a huge range of keys and can help you find the best one for your car. They can assist you in programming your vehicle's chip which is needed to use the device. Laser cut keys are more secure than flat keys. They have a lock cylinder that is much harder to pick, and they are only duplicated using expensive laser key cutting machines or specialized software. This technology is more common in high-end cars, but it is now accessible in a wide range of low-cost cars too. Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) key. They come with a resistor black on the blade of the key. It can be programmed to any of fifteen possible values to stop it from starting a car that's not designed to. These keys are costly and require the use of a key programming machine which is only available at certain locksmiths. VATS Keys Before transponder keys and vehicles with computer chips built in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS makes use of a regular key with a pellet of resistance embedded in it to confirm that the correct key is used to start the vehicle. The black VATS pellet in the center of the VATS key isn't an electronic chip like the ones used in modern smart keys. It is simply a carbon block properly sized to carry an exact electrical resistance. GM employed 15 different resistances for the VATS Pellets. They attached them to key blades so that, when the key is turned in the ignition a coded signal is sent to module. If the signal is in line with that of the transistor in a VATS pellet then the relay in starter circuit will activate and the engine will begin to run. This isn't a way to make a car secure from theft however it will delay the thief by at least 15 to 20 minutes. After a long period of use the VATS module may begin to wear out. The two wires that connect the ignition are moved each time a key is introduced. Over time, the wires may begin to break. Once enough wires are broken the signal is lost to the module and the car will not start. You can solve this issue at home by decoding your VATS code. It's not hard to determine the resistance of a key with a multimeter. All you have to do is place one of the leads of your ohm gauge on the prongs of metal that are hanging out on both sides of the key, and then examine the display of your ohm meter to determine the resistance of your key. This method is also a good way to test the new key to determine if it will work in your vehicle. Remove the ignition key first before you test it. In the event that it is not removed, the key may have an incorrect VATS and will not work in your vehicle.
