car keys cut and programmed Key Cutting Explained
Car key cutting is a lot more than just shaping a piece of metal. It is a sophisticated process that guarantees security, functionality and long-term use of the keys.
It is not uncommon to lose keys to your car or have them break in the lock. You will need an alternative car key to ensure that you are able to drive your car at all times.
Transponder Keys
If your car was constructed in the last 20 years, it is likely that it has a transponder chip. These chips are tiny microchips in the handle of your key that transmit a signal to the vehicle's onboard computer when you are using it. The computer on board scans the digital serial numbers in the chip and only allows the car to start if it is the correct one. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to take over it.
The microchip in your car key transmits an unintentional radio signal to the receiver inside the car. This radio signal activates your microchip which then transmits instructions to the onboard computer of the car. The car will recognize this code and only allow it to start when it is the correct one. This prevents "hot wiring" or other methods to steal cars.
Locksmiths that offer these services can make car keys with chips. They can also be purchased at a few automotive stores, such as AutoZone. These stores offer a wide selection of keys, and can assist you in finding the right one for your car. They can even assist you to program the chip to your vehicle, which is required to make it work.
Laser cut keys are more secure than flat keys. These keys feature a lock cylinder that is much harder to pick, and they can only be duplicated using expensive laser key cutting equipment or specially designed software. This type of technology is typically found in high-end cars, but is now available on a variety of affordable models.
Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor on the blade of the key that is programmed with one of fifteen possible values to prevent them from starting a car that it's not designed cost to get a key cut. These keys are expensive and require a key programming machine, which is only available through certain locksmiths.
VATS Keys
Before transponder keys and cars that had computer chips built in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a pellet of resistance embedded inside it to confirm that the correct key is being 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's simply a carbon block that is sized appropriately to have a specific electrical resistance value.
GM employed 15 different resistance values for the VATS pellets and connected them to the key's blade to ensure that, when the key is turned in the ignition a coded signal will be transmitted to the module. If the signal is in line with the one of the transistors in a VATS pellet then the relay in starter circuit will turn on and the engine will start to run. This doesn't make a car theft proof however it will delay the thief by at most 15 to 20 minutes.
After a lot of usage the VATS module could start to wear out. The two small wires in the ignition are moved every time the key is placed. Over time the wires could begin to break. Once enough wires are broken, the signal to the module is lost and the module won't be able to start the car.
The good news is that you can solve this issue yourself by decoding your VATS key. It's not difficult to determine the resistance of a key using the multimeter. All you have to do is put one of the leads of your ohm gauge on the metal prongs that are visible on both sides of the key, and then examine the display of your ohm meter to determine the resistance value of your key.
This method is also a good way to test the new key to determine if it will work in your car. Just be sure to remove the key from the ignition before you begin testing it, otherwise the new key could have an incorrect VATS number and will not function in your car.
