Car Key Cutting Explained

Cutting a car key is more than just bending metal. It is a complex procedure that ensures safety, functionality and the longevity of keys.

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

Transponder Keys

Transponder chips are likely be added to cars that were built in the last 20 years. These microchips are located in the key's handle and send a signal to the onboard computers in your vehicle when you turn the key. The computer on board detects the digital serial number within the chip and allows the car to start if it is the correct one. This helps prevent theft of cars since thieves need to know your unique serial number in order to have a chance at hijacking it.

The microchip in the key transmits a low-level signal to the car's receiver. This radio signal activates your microchip which then transmits code 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 to steal cars.

Locksmiths who offer these services can create car keys with chips. They are also available at some automotive retailers like AutoZone. They have a huge range of keys and can assist you in finding the right one for your vehicle. They can help you program your car's chip, which is required to use the device.

There are also laser cut keys, which are more secure than conventional flat keys. These keys feature an cylinder for locking that is much harder to pick, and are only duplicated using expensive laser key cutting machines or with special software. This type of technology is typically found in high-end vehicles, however it is now available in many affordable models of automobiles as well.

Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys contain a resistor that's black on the blade of the key. It can be programmed with one of 15 possible values to prevent it from starting a vehicle that'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 key that has an internal resistor to verify that the correct key was used to start the car. The black VATS pellet in the center of the VATS key isn't a chip like those found on modern smart keys, it is simply a carbon block that is sized appropriately to have an exact electrical resistance.

GM used 15 different resistance values for the VATS pellets. They attached them to the key's blade to ensure that, when the key cut service is turned on the ignition the coded signal is sent to the module. If the signal matches that of the transistor in a VATS pellet then the relay in the starter circuit will be activated and the engine will begin to run. This doesn't make a vehicle theft proof however it can delay the thief by at least 15 to 20 minutes.

Unfortunately, after a long period of usage, the VATS module in your car may begin to wear out. Each time a key is inserted into the ignition it moves two very small wires within the ignition, and, over time, the wires can start to break. If enough wires are damaged, the signal is lost to the module and the car will not start.

You can resolve this issue at home by decoding your 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 find the resistance value by placing one of the leads on the prongs of metal on both sides of your key.

This can also be a good method to test a new key to determine whether it will work in your car. Just be sure to remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and may not function in your car.

Smart Key Fobs

Key fobs today are more than simply unlock and start the car. They often have advanced features that most owners aren't aware of. They can be employed as a security tool or as a theft deterrent. They can remotely lock and unlock your doors, emit sounding sounds to help find your vehicle in a parking lot and even allow you to summon your vehicle by pressing the button on your phone. This is a lot more than you could ever expect from the traditional keychain remote. Unfortunately, all that extra functionality also means that smart key fobs can be pricier to replace than standard keychain remotes, and they usually need to be programmed by the dealer.

It's a steep price for a device that is often tossed around in purses and pockets where it can be damaged, dropped, or exposed to extreme temperatures and water. Certain automakers have devised methods to shield smart key fobs from common electronic threats, including relay attacks. They are typically utilized in conjunction with a remote-start hack that allows thieves to access the settings of your vehicle by sending a fake signal from another nearby transmitter.

To safeguard a smart fob, you can store it in a metal case or put it in an RFID blocking case. This will block the transmission of these signals. However, having to remove the key fob from a protective case every time you need to use it is not a good way to enjoy the benefits of the technology.

Traditional Keys

The classic car key is made of a single piece of steel with a series grooves carved into it. These grooves are made to fit certain locks. They can open your locks and start your car, provided you haven't replaced them by the remote key or smart key. The only disadvantage of using an old-fashioned car key is that you have to physically insert it into the ignition to start the engine. If your car key has been lost or broken, you will need to visit an Gainesville locksmith to get a new one made.

Based on the amount of time that has passed since the last time you had your keys cut there are a variety of options available for you to pick from when it comes to getting another copy made. Certain keys are cut using mechanical machines or lasers, while others are cut with added security features.

Some of these features that come with modern-day keys include encryption as well as other anti-theft mechanisms. Encryption makes it harder for thieves to duplicate keys or take locks. Transponder chips are an additional security feature that prevents theft. They are incorporated into the key and connect to your vehicle. This means that it can only effective only when you're within certain distance.

If you choose to use a traditional key, your locksmith can design an entirely new key using the standard cutter machine that can be bought from most hardware stores. This is cheaper than a key fob, or transponder, and you can still operate your locks, trunk, and doors.
