Car Key Cutting Explained

Cutting a car key is more than just bending a piece metal. It is a complex process that ensures safety, functionality and durability of keys.

It is not unusual to lose your car key or even break it in the lock. You'll require an alternative car key to ensure that you are able to drive your car at all times.

Transponder Keys

Transponder chips are likely to be fitted in vehicles built within the past 20 years. These chips are tiny microchips located in the key cut place's handle that transmit signals to the car's onboard computer when you use it. The computer onboard checks the serial number of the chip prior to it allows the car to start. This prevents thieves from stealing your car, as they would need to know the unique serial number.

The microchip in the key transmits a low-level signal the receiver within the car. This radio signal activates your microchip that then transmits the instructions to the onboard computer of the car. The car will only start when it recognizes the code. This stops "hot wiring" or other methods to steal cars.

Car keys with chips can be made at an authorized locksmith who offers these services. They can also be bought at a few automotive stores like AutoZone. These stores offer a wide selection of keys, and can assist you in finding the appropriate one for your vehicle.

Laser cut keys are more secure than flat keys. They have a lock cylinder that is more difficult to pick, and they are only duplicated using expensive laser key cutting machines or with specialized software. This technology is most common in luxury cars but is now accessible on many affordable models.

Another kind of key for cars that is hard to duplicate is the VATS (vehicle anti-theft system) key. These keys come with a resistor black on the blade of the key. It can be programmed to one of a variety of values to prevent it from starting a vehicle that's not intended to. These keys are expensive and require the use of a key programming machine which is only available at certain locksmiths.

VATS Keys

Before the advent of transponder keys and automobiles equipped with computer chips that control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a resistor pellet embedded inside it to confirm that the correct key is used to start the car. The black VATS Pellet located in the middle of a VATS Key isn't a smart chip like those used on the majority of modern keys. It is merely carbon or a block that is sized to have an electrical resistance value.

GM used 15 different resistances for the VATS Pellets. They connected them to key blades so that, when the key is turned in the ignition a coded signal is sent to 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 burglary however, it can deter the thief for a minimum of 15 to 20 minutes.

Unfortunately, after a significant amount of use the VATS module in your car may 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. When enough wires have been broken the signal goes out to the module and the car will not start.

You can resolve this issue at home by decoding your VATS code. You'll need a multimeter and a chart to find out 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 prongs of metal on both sides of your key.

This is a great opportunity to test a new key and determine whether it works in your car. Remove the key from the ignition first before you test it. If not, the key may have an incorrect VATS, and will not work in your car.
