Car Key Cutting Explained

Cutting the car key is more than just bending a piece of metal. It is a complex procedure that ensures security, functionality and long-term use of the keys.

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

Transponder Keys

Transponder chips are likely to be fitted in vehicles built in the last 20 years. These microchips are tiny located in the key's handle that transmit a signal to the vehicle's onboard computer when you use it. The onboard computer reads the digital serial number inside the chip and allows the car to start if it is the right one. This stops thieves from taking over your vehicle because they'd have to be aware of the unique serial number.

The microchip inside your car keys transmits an unintentional radio signal to the receiver inside the car. This radio signal activates the microchip, and it then sends an encoded 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 "hot wiring" or other methods to steal cars.

Car keys with chips can be made by a locksmith that 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 vehicle. They can assist you in programming the chip in your vehicle that is required to use the device.

There are also laser cut keys, which are more secure than traditional flat keys. These keys feature an cylinder for locking that is much harder to pick, and they can only be duplicated with expensive laser key cutting equipment or specially designed software. This technology is most commonly found in high-end vehicles, but is now available on many affordable models.

The VATS (vehicle-anti-theft system), key is another type of key that is difficult to duplicate. These keys contain a resistor that's black on the blade of the key. It can be programmed to any of fifteen possible values to stop it from starting a vehicle it's not designed to. These keys are costly and require an instrument for programming keys, which is only available at a few locksmiths.

VATS Keys

Before transponder keys and vehicles with computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a pellet of resistance embedded within it to verify that the correct key is used to start the vehicle. The VATS pellet that is black that is located in the middle of the VATS Key isn't a smart chip as used on the majority of modern keys. It's just carbon or a block that is sized to provide an electrical resistance.

GM employed 15 different resistance values for the VATS pellets. They connected them to the key's blade, so that when the key is turned on the ignition a coded signal will be transmitted 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 starts to run. This doesn't make a car burglar-proof however it could delay the thief for a minimum of 15 to twenty minutes.

After a long period of use the VATS module could start to wear out. Each time a key is inserted into the ignition it moves two very small wires inside the ignition and with time, the wires can begin to break. Once enough wires are broken the signal goes out to the module and the car won't start.

The good news is that you can fix this problem yourself at home by decoding your own VATS key. You'll require a multimeter and a chart to find out the resistance value of your key, but it's not that difficult. You can determine the resistance value near By putting one of the leads on the prongs made of metal on both sides of your key.

This is a great opportunity to test a brand new key and see whether it will work in your car. Remove the ignition key first before you test it. If not the key could have an incorrect VATS and not work in your vehicle.

One way to protect the key fob's RFID is to put it in an aluminum case or an RFID blocking case that prevents the transmission of these signals. However, having to take the key fob from its protective case every time you use it undermines the convenience of the technology.

Some newer policies such as auto club memberships or extended warranties can cover the cost of replacing the fob, or reimburse you if it gets lost.
