Car Key Cutting Explained
Car key cutting is much more than just forming the metal. It is a complex process that guarantees security, function and long-term use of keys.
It is not unusual to lose your car key or have it break off in the lock. You'll 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 added to cars that were that were built in the last 20 years. These microchips are located in the key's handle and send a signal to the onboard computers in your vehicle when you press the key. The computer on board scans the digital serial numbers inside the chip and allows the car to start if it's the right one. This prevents car theft since thieves need to know your unique serial number to be able to take over it.
The microchip inside your car key transmits a low-level radio signal to the car's receiver. This radio signal activates your microchip which then transmits code to the computer onboard of the car. The car will only begin if it recognizes this code. This prevents the use of "hot wiring" and other methods of theft of cars.
Car keys with chips can be made at an authorized locksmith who offers these services. They can also be bought at some automotive retailers, such as AutoZone. They have a huge range of keys and can help you find the best one for your vehicle. They can also help you program the chip to your vehicle, which is required to use it.
Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys due to having a lock that is 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 cars, but is now available in a wide range of low-cost models.
Another kind of car key that's difficult to duplicate is the VATS (vehicle anti-theft system) key. They have a resistor that is black on the blade of the key. It can be programmed with one of fifteen possible values to prevent it from starting a vehicle that's not designed to. These keys are expensive and require a key programming machine, which is only available through certain locksmiths.
VATS Keys
Before transponder keys or vehicles with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses a key with an internal resistor to ensure that the correct key was used to start the car. The VATS pellet that is black that is located in the middle of the VATS Key is not a smart chip like those present on modern keys. It's just carbon or a block that is sized to provide an electrical resistance value.
GM employed 15 different resistances for the VATS Pellets and connected them to key blades so that, when the key was turned on, a coded message is sent to the module. If the signal matches 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 could delay the thief for a minimum of 15 to 20 minutes.
Unfortunately, after a significant amount of use the VATS module in your car can start to wear out. Every time a key is inserted into the ignition, it moves two tiny wires within the ignition, and with time, the wires may begin to break. If enough wires are damaged, 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. You'll need a multimeter and a chart to determine the resistance value of your key, but it's not difficult at all. You can find 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 determine whether it works in your vehicle. Make sure you remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and not work in your car.
