Car Key Cutting Explained

Car key cutting is a lot more than just shaping an object of metal. It is a complicated procedure that ensures safety, functionality and long-term use of keys.

It is not unusual to lose your car keys or even have them break into the lock. To ensure that you can always drive your car, you will need to have a replacement key cut.

Transponder Keys

If your car was constructed within the last 20 years, it is likely that it has transponder chips. These microchips are located in the handle of the key and send a signal to your vehicle's onboard computers when you turn the key. The computer in the car is able to verify the serial number digitally of the chip before it allows the car to start. This prevents thieves from taking over your vehicle because they'd have to be aware of the unique serial number.

The microchip in your car keys transmits a low-level radio signal to the receiver inside the car. This radio signal activates the microchip which then transmits instructions to the onboard computer of the car. The car will only start if it recognizes this code. This will stop "hot wiring" or other methods to steal cars.

Car keys with chips can be created at an authorized locksmith laser cut keys near me who offers these services. Some auto dealers like AutoZone sell them. These stores have a wide range of keys and will assist you in selecting the best one for your car. They can even help you program the chip to your vehicle, which is required to make it work.

Another kind of car key that is difficult to duplicate is the VATS (vehicle anti-theft system) key. They contain a resistor that's black on the blade of the key. It can be programmed to any of 15 possible values to stop it from starting a car that's not designed to. These keys are costly and require the use of a key programming machine which is only available at a few 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 makes use of a regular key with a resistor pellet embedded inside it to confirm that the correct key cutting services is being used to start the car. The VATS pellet in black in the middle of a VATS Key is not a smart chip like those used on the majority of modern keys. It is simply a block or carbon that is sized to hold an electrical resistance.

GM employed 15 different resistances for VATS pellets and connected them to key blades so that, when the key was turned on, the key blades transmit a coded message to module. If it 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 however it can delay the theft by at minimum 15 to 20 minutes.

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

You can solve this issue at home yourself by decoding your VATS key. You'll need a multimeter and a chart to find out the resistance value of your key, but it is not that difficult. All you have to do is place one of the leads of your ohm meter on the prongs made of metal sticking out on both sides of the key, and then read the ohm meter's display to find out the resistance of your key.

This can also be a good method to test a new key to determine if it will work in your vehicle. Remove the key from the ignition first before you test it. In the event that it is not removed the key may have an incorrect VATS and not work in your car.

However, the necessity of removing the key fob from a case that is protected each time you use it undermines the convenience of the technology.
