Car Key Cutting Explained

Car key cutting is much more than just forming the metal. It is a complex procedure that ensures security, efficiency and long-term use of the keys.

It is not unusual to lose keys to your car, or have them break through the lock. You'll require a replacement car key to ensure that you can drive your car at all times.

Transponder Keys

If your car was built within the last 20 years, it's likely that it has transponder chips. These chips are small microchips inside the handle of your key that send signals to the car's onboard computer when you are using it. The onboard computer scans the digital serial numbers inside the chip and allows the mobile car key cutter to start if it's the right one. This stops thieves from stealing your car, as they would need to know the unique serial number.

The microchip inside your car keys transmits an low-level radio signal to the car's receiver. The radio signal activates the microchip, and it then sends an informational code to the car's onboard computer. The car will be able to recognize this code and only allow it to start only if it is the correct one. This will stop "hot wiring" or other methods to steal cars.

Locksmiths who offer these services can create keys for cars that contain chips. Some auto dealers like AutoZone sell keys with chips. They have a huge selection of keys, and can help you find the best one for your car. They can also help you programme the chip into your vehicle, which is required for it to function.

Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is much harder to pick, and can only be duplicated with expensive laser key cutting machines or with special software. This technology is most common in high-end cars however, it is now available in a wide range of low-cost models.

The VATS (vehicle-anti-theft system) key is a different type of key that's difficult to duplicate. These keys have a resistor that is black on the blade of the key. It can be programmed to one of a variety of values to stop it from starting a car that's not intended to. They are expensive and require the use of a key programming machine which is only available at a few locksmiths.

Keys to VATS

Before transponder keys and cars with computers built-in to 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 in the middle of a VATS Key isn't a smart chip as present on modern keys. It is merely a block or carbon that is sized to provide an electrical resistance.

GM used 15 different resistance values for the VATS pellets. They attached 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 is in line with that of the transistor in a VATS pellet then the relay in starter circuit will be activated and the engine will begin to run. This doesn't make a car safe from burglary however it could delay thieves for at least fifteen to twenty minutes.

Unfortunately, after a significant amount of use, the VATS module in your car can begin to wear out. Each time the key is inserted into the ignition, it moves two very small wires within the ignition, and with time, the wires can begin to break. When enough wires break, the signal to the module gets lost and the module won't be able to start the car.

You can solve this issue at home yourself by decoding your VATS key. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it is not difficult at all. All you have to do is place one of the leads of your ohm gauge on the prongs of metal that are sticking out on both sides of the key, and then look at the display of the ohmmeter to find out the resistance value of your key.

This is a great method to test out a new key and determine if it works 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 work in your car.

Smart Key Fobs

Fortunately there are automakers who have developed methods to shield smart key fobs from the most common kinds of electronic attacks, such as relay attacks. These are usually used in combination with a remote-start hack that allows thieves to access your vehicle's settings by transmitting false signals from a nearby transmitter.

One method of protecting the key fob's RFID is to put it in a metal case or use an RFID blocking case that prevents the transmission of these signals. However, having to take the key fob from a protective case each time you need to use it is not a good way to enjoy the benefits of the technology.

Some newer policies such as auto club memberships and extended warranties will pay for replacing the fob or reimburse you if it is lost. You can also avoid paying new-car dealership fees by having your fob cloned by a locksmith or hardware store that offers key-fob-cloning services.

Traditional Keys

These keys can open your locks and start your car, provided you don't replace them with the remote key or smart key. The only drawback of using a traditional key is that it must be physically put into the ignition to start the vehicle.

Some of these advanced features that are included in modern-day keys include encryption and other anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or open locks. Transponder chips are another anti-theft feature. They are embedded into the key and connect to your vehicle. This makes it only work only when you're within a specific distance.
