Car Key Cutting Explained

Cutting the car key is more than just bending metal. It is a complicated process that guarantees security, function and durability of keys.

It is not uncommon to lose your car keys or have them break through the lock. To ensure that you are able to always drive your vehicle, you will require a replacement key cut.

Transponder Keys

Transponder chips will likely be fitted in vehicles that were built in the last 20 years. These chips are tiny microchips located in the key's handle which transmit an electronic signal to the car's onboard computer whenever you use it. The onboard computer is able to verify the serial number digitally of the chip prior to it allows the car to begin. This prevents spare car key cutting (he has a good point) theft since thieves need to know your unique serial number to be able to steal it.

The microchip in your car key transmits a low-level radio signal to the car's receiver. This radio signal activates your microchip, which transmits a 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 of stealing cars.

Car keys with chips can be made by locksmiths that offer these services. They can also be purchased at certain automotive stores like AutoZone. These stores offer a wide variety of keys, and can assist you in choosing the best one for your vehicle. They can even assist you to program the chip to your vehicle, which is necessary to use it.

Laser cut keys are more secure than flat keys. They have a lock cylinder that is much more difficult to pick, and they can only be duplicated with expensive laser key cutting machines or specially designed software. This type of technology is typically found in high-end vehicles, however it is now being used in a wide range of low-cost automobiles as well.

The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys are black with a resistor on the key blade that is programmed with one of 15 potential values to prevent the car from starting that it's not designed to. These keys are more expensive to purchase and require a special key programming machine that can only be found at a few locksmiths.

Keys to VATS

Before transponder keys or cars that had computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded in it to confirm that the correct key is being used to start the car. The VATS pellet that is black located in the middle of a VATS Key isn't an electronic chip that is like those found on most modern keys. It is simply carbon or a block which is sized to hold an electrical resistance.

GM employed 15 different resistance values for VATS pellets and connected them to the blade of the key so that when the key is turned in the ignition the coded signal is transmitted to the module. If the signal is in line with the signal of the transistor in a VATS pellet then the relay in the starter circuit will turn on and the engine will begin to run. This does not make a car keys cut by code safe from burglary however, it can deter the thief for a minimum of 15 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 can start to break. Once enough of the wires are broken the signal to the module gets lost and the module won't be able to start the car.

You can resolve this issue at home yourself by decoding your VATS code. It's not hard to determine the resistance of a key with the multimeter. You can determine the resistance value by putting one of the leads on the prongs made of metal on both sides of your key.

This is also a good way to test a new key to determine whether it works 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 vehicle.

Key fobs today do more than just unlock or start the vehicle. They often have advanced features that a lot of owners aren't aware of. They can be used as a security device or as a deterrent to theft. They can remotely lock and unlock your doors, emit noises that help you find your car in a parking space or allow you to summon your vehicle by pressing a button on your smartphone. This is more functionality than you can get from a traditional keychain remote. Smart key fobs are more expensive to replace due to their additional functions.

Certain automakers have devised methods to shield smart key fobs from common electronic threats, including relay attacks. These are usually used in combination with remote-start hacks that allow thieves to gain access to your vehicle's settings by transmitting an untrue signal from a nearby transmitter.

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

Certain policies that are more recent, such as auto club memberships or extended warranties will pay for replacing the fob or reimburse you if it gets lost.

Traditional Keys

These keys can open your locks and start your vehicle, provided that you don't replace them with an electronic key or a remote key. The only disadvantage of using traditional keys is that it needs to be physically placed into the ignition to start the car. If your traditional key has been lost, damaged or stolen, you'll need to visit an Gainesville locksmith to get new keys made from the blank.

Based on the amount of time that has passed since the last time you got your keys cut, there are several different alternatives to choose from when it comes to having another copy made. Certain keys are cut using mechanical machines, while others are laser-cut with security features that are enhanced.

Some of these advanced features that come with the modern-day keys include encryption and other anti-theft mechanisms. Encryption makes it harder for thieves to duplicate keys or open locks. Transponder chips are a different anti-theft feature. They are embedded in the key and can communicate with your vehicle. This makes it only effective when you're within a certain distance.
