Car Key Cutting Explained

Car key cutting is a lot more than just forming an object of metal. It is a complex process that ensures safety, functionality and longevity of keys.

It is not uncommon to lose your car key or have it break off in the lock. You will need a replacement car key to ensure you can drive your car at all times.

Transponder Keys

Transponder chips are likely to be installed in cars that were built in the last 20 years. These microchips are tiny located in the key's handle which transmit signals to the car's onboard computer when you are using it. The computer onboard checks the serial number of the chip before it allows the car to begin. This prevents car theft, as thieves would need to know your unique serial number to be able to steal it.

The microchip in the key transmits a low-level signal the car's receiver. The radio signal activates the microchip, and it then sends a code to the car's onboard computer. The car will be able to recognize this code and only allow it to start only if the key is the right one. This stops the use of "hot wiring" and other methods of stealing cars.

Car keys with chips can be made by a locksmith that offers these services. Some car dealers, like AutoZone sell them. These stores have a wide selection of keys and can assist you in choosing the appropriate one for your vehicle. They can help you program your vehicle's chip which is needed for the device to function.

They can only be duplicated with expensive laser key cutting car cutting machines, or with specialized software. This technology is more prevalent in high-end cars, but it is now being used in a wide range of low-cost cars too.

The VATS (vehicle-anti-theft system) key is a different type of key that is difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of 15 possible values to prevent them from starting a car that it's not designed to. These keys are more expensive to buy and require a specific emergency key cutting programming machine that is only found at some locksmiths.

VATS Keys

Before the advent of transponder keys as well as cars equipped with computer chips that control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System).

The VATS pellet that is black in the middle of a VATS key cutting services cut near me open now (Continue) is not an electronic chip that is like those present on modern keys. It is simply carbon or a block that is sized to have an electrical resistance.

GM employed 15 different resistances for VATS pellets and attached them to key blades in a way that when the key is turned on, a coded message is sent 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 does not make a car safe from burglary however, it can deter a thief for at least fifteen to twenty minutes.

After a lot of usage, the VATS module can begin to wear out. Each time the key is inserted into the ignition it reroutes two small wires inside the ignition, and, over time, the wires may begin to break. If enough wires are damaged the signal goes out to the module and the car won't start.

The good news is that you can solve this issue yourself by decoding your own VATS key. You'll need a multimeter and a chart to determine the resistance value of your key, but it is not difficult at all. You can determine the resistance value by placing one of the leads on the metal prongs on both sides of your key.

This method is also a great way to test a new key to see if it will work in your vehicle. Just be sure to remove the key from the ignition prior to testing it, or else the new key could be displaying an incorrect VATS number and will not function in your car.

They are usually paired with a remote start hack that gives thieves access to your vehicle's settings by the transmission of a fake signal by another transmitter nearby.

One way to protect the key fob's RFID is to store it in a metal case or use an RFID blocking case that blocks the transmission of these signals. However, having to take the key fob from a protective case every time you want to use it is not a good way to enjoy the benefits of the technology.

Certain policies that are more recent like auto club memberships and extended warranties, will pay for replacing the fob or reimburse you in the event that it is lost. You can also avoid paying dealership fees by having your fob copied by a locksmith or hardware store that offers key-fob-cloning services.
