Ten Cut Car Key Myths You Should Never Share On Twitter > 자유게시판

Car Key Cutting Explained

Car key cutting is more than simply shaping a piece of metal. It is a complex procedure that ensures safety, functionality and long-term use of the keys.

It is not uncommon to lose keys to your car or have them break through the lock. To ensure you're able to always drive your vehicle, you will need a new key cut.

Transponder Keys

Transponder chips will likely be installed in cars that were built in the last 20 years. These microchips are located in the handle of the key and transmit a signal to the onboard computers of your vehicle when you press the key. The onboard computer checks the digital serial number of the chip before it allows the car to begin. This stops theft of vehicles as thieves would have to know your unique serial number to have a chance at hijacking it.

The microchip in your car key sends a low-level radio signal to the car's receiver. The radio signal activates your microchip that then transmits the code to the onboard computer of the car. The car will only start only if it recognizes the code. This will stop 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. Some car dealers, like AutoZone offer keys with chips. These stores offer a wide selection of keys, and can help you find the right one for your car. They can also help you programme the chip into your vehicle, which is essential for it to function.

Another type of car key that's difficult to duplicate is the VATS (vehicle anti-theft system) key.

These keys are more expensive to buy and require a specific key programming device that can only be found at a few locksmiths.

VATS Keys

Before transponder keys or cars with computer chips that control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an embedded resistor to confirm that the right key was used to start the car. The black VATS pellet inside the middle of a VATS key is not an electronic chip as found on modern smart keys, it's simply a carbon block appropriately sized to have a specific electrical resistance value.

GM employed 15 different resistance values for the VATS pellets and connected them to the blade of the key so that when the key is turned in the ignition a coded signal will be sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine begins to run. This doesn't make a car safe from theft, but it will delay the theft by at least 15 to 20 minutes.

After a lot of usage the VATS module may start to wear out. Each time the key is inserted into the ignition, it moves two tiny wires inside the ignition and, over time, the wires can start to break. Once enough wires are broken the signal to the module gets lost and it won't start the car.

You can solve this issue at home by decoding your VATS code. It's not difficult to determine the resistance value of a key by using the multimeter. You can find the resistance value by placing one of the leads on the prongs made of metal on both sides of your key.

This is also a good way to test a new key to determine if it will work in your vehicle. Make sure you remove the key from the ignition before you begin testing it, as the new spare key cutting could be displaying an incorrect VATS number and will not function in your car.
