Car Key Cutting Explained
Car key cutting is a lot more than just forming a piece of metal. It is a sophisticated process that guarantees safety, functionality and the longevity of keys.
It is not uncommon to lose your car key or have it break off in the lock. To ensure you're able to always drive your car, you will need a new key cut.
Transponder Keys
Transponder chips are likely to be added to cars that were built in the last 20 years. These microchips are situated in the key's handle and transmit a signal to the onboard computers in your vehicle when you turn the key. The computer onboard checks the serial number digitally of the chip before it allows the car to begin. This prevents car theft as thieves would have to know your unique serial number to be able to take over it.
The microchip in the key sends a low-level signal the car's receiver. This radio signal activates the microchip, and it then sends an informational code to the car's onboard computer. The car will be able to recognize the code and only allow it to start only if it is the correct one. This prevents the use of "hot wiring" and other methods of taking cars.
Locksmiths who provide these services can make car keys with chips. Some automotive retailers such as AutoZone sell them. These stores offer a wide selection of keys, and can assist you in finding the best one for your car. They can assist you in programming the chip in your vehicle, which is required for the device to function.
Laser cut keys are more secure than flat keys. These keys are more secure than flat keys due to the fact that they have a lock that is harder to pick. They can only be duplicated with expensive laser key cutting equipment, or with specialized software. This technology is more common in high-end cars, but it is now being used in a wide range of low-cost automobiles as well.
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 to one of fifteen possible values to stop it from starting a vehicle it's not intended to. you can try these out are expensive and require an instrument for programming keys, which is only available through certain locksmiths.
VATS Keys
Before the advent of transponder keys and cars with built-in computer chips to control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key that has a resistor pellet embedded in it to confirm that the correct key is being used to start the car. The VATS pellet that is black in the middle of a 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 have an electrical resistance.
car keys cut and programmed used 15 different resistance values for the VATS pellets. They connected the key's blade so that when the key is turned on in the ignition a coded signal will be sent to the module. If the signal matches that of the transistor 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 secure from burglary however, it can deter the thief for a minimum of 15 to twenty minutes.
Unfortunately, after a lot 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 over time the wires could begin to break. Once enough wires are broken, the signal to the module is lost and it won't start the car.
The good news is that you can solve this problem yourself at home by decoding your VATS key. You'll require a multimeter as well as a chart to find out the resistance value of your key, but it's not difficult at all. All you have to do is put one of the leads of your ohm meter onto the prongs made of metal sticking out on both sides of the key. Then look at the display of the ohmmeter to determine the resistance value of your key.
This can also be a good method to test the new key to determine 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 not work in your car.
