Car Key Cutting Explained
Car key cutting is a lot more than just shaping the metal. It is a complicated procedure that guarantees security, function and long-term use of keys.
It is not uncommon to lose keys to your car or have them break through the lock. You will need an alternative car key to ensure that you are able to drive your car at all times.
Transponder Keys
Transponder chips will likely be installed in cars built within the past 20 years. These microchips are located in the handle of the key and send a signal to the onboard computers of your vehicle when you use the key. The onboard computer examines the digital serial number of the chip before allowing the car to begin. This stops theft of vehicles, as thieves would need to know your unique serial number to have a chance at hijacking it.
The microchip inside your car key transmits an unintentional radio signal to the car's receiver. This radio signal activates the microchip, which then transmits a code to the car's onboard computer. The car will only start if it recognizes this code. This prevents "hot wiring" or other methods to steal cars.
Car keys with chips can be made by an authorized locksmith who offers these services. They can also be bought at certain automotive stores, such as AutoZone. They have a huge selection of keys, and can assist you in choosing the right one for your vehicle. They can help you program the chip in your vehicle that is required for the device to function.
Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is much harder to pick, and are only duplicated using expensive laser key cutting machines or specialized software. This technology is most common in high-end vehicles but is now accessible on a variety of affordable models.
The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys have a resistor that is black on the blade of the key. It can be programmed to one of a variety of values to prevent it from starting a vehicle that's not intended to. These keys are costly and require an instrument for programming keys, which is only available at a few locksmiths.
VATS Keys
Before transponder keys or vehicles with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded within it to verify that the correct key is used to start the car. 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 a specific electrical resistance value.
GM employed 15 different resistances for VATS pellets and connected the key blades to them so that, when the key was turned on, the key blades transmit a coded message to the 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 turn on and the engine will start to run. This doesn't make a vehicle theft proof however it will delay the thief by at minimum 15 to 20 minutes.
Unfortunately, after a long period of use the VATS module in your car could begin to wear out. The two wires that connect the ignition are moved every time the key is inserted. Over time, the wires may start to break. Once enough of the wires break, the signal to the module gets lost and the module won't be able to start the car.
The good news is that you can fix this issue at home by decoding your VATS key. You'll need a multimeter and a chart to find out the resistance value of your key, but it's not that difficult. You can determine the resistance value by putting one of the leads on the prongs made of metal on both sides of your key.
This is a great way to test a new key and see whether 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 could have an incorrect VATS and will not function in your vehicle.
