Car Key Cutting Explained

Cutting keys for cars is more than just bending a piece of metal. It is a sophisticated process that guarantees safety, functionality, and longevity of the keys.

It is not unusual to lose keys to your car, or have them break in the lock. You will need a new car key in order to ensure that you are able to drive your vehicle at all times.

Transponder Keys

Transponder chips are likely be installed in cars that were built in the last 20 years. These microchips are tiny inside the handle of your key that send signals to the car's onboard computer when you are using it. The computer in the car examines the serial number digitally of the chip prior to giving the car permission to start. This prevents thieves from stealing your car since they'd need to be aware of the unique serial number.

The microchip in the key sends a low-level signal the receiver within the car. This radio signal activates the microchip, and it then sends an encoded code to the car's onboard computer. The car will recognize this code and only allow it to start if the key is the correct one. This prevents the use of "hot wiring" and other methods of taking cars.

Car keys with chips can be made at a locksmith that offers these services. Some automotive retailers such as AutoZone sell keys with chips. These stores have a large selection of keys, and can help you find the best one for your vehicle. They can also help you program the chip to your vehicle, which is required to make it work.

Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is much harder to pick, and they can only be duplicated with expensive laser key cutting machines or with specialized software. This type of technology is typically found in high-end vehicles but is now accessible on a variety of affordable models.

Another kind of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. The keys are black with a resistor in the key blade that is programmed with one of fifteen possible values to stop the mobile car key cutting near me from starting that it's not designed to. These keys are expensive and require a key programming machine, which is only available at certain locksmiths.

VATS Keys

Before transponder keys or vehicles with computer chips built in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses a key with an embedded resistor to confirm that the right key was used to start the car. The VATS pellet in black that is located in the middle of the VATS Key isn't a smart chip as present on modern keys. It's just a block or carbon that is sized to provide an electrical resistance.

GM employed 15 different resistances for VATS pellets and connected them to key blades in a way that, when the key was turned on, a coded signal is sent 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 activate and the engine will begin to run. This does not make a car burglar-proof however it could delay a thief for at least fifteen to twenty minutes.

Unfortunately, after a lot of use the VATS module in your car can begin to wear out. Every time a mobile key cutting near me is inserted into the ignition, it moves two tiny wires inside the ignition, and with time, the wires could begin to break. When enough wires are broken then the signal to the module is lost and it won't start the car.

The good news is that you can fix this issue at home by decoding your VATS key. You'll require a multimeter and a chart to determine the resistance value of your key, but it's not difficult at all. All you need to do is place one of the leads of your ohm meter on the metal prongs that are sticking out on both sides of the key. Then read the ohm meter's display to determine the resistance value of your key.

This can also be a good method to test a new key to determine if it will work in your car. Remove the key from the ignition first before you test it. Otherwise the key may have an incorrect VATS, and will not work in your car.

Smart Key Fobs with Smart Keys

Key fobs today can do more than unlock or start the car. They can also be an alarm system and a burglar deterrent, with a lot of them featuring advanced features that owners may not be aware of. They can remotely lock and unlock your doors, make noises that help you find your car in a parking lot, or even allow you to summon your vehicle by pressing a button on your smartphone. This is a lot more than you could ever imagine from a traditional keychain remote. However, all that additional features can mean that smart key fobs can be pricier to replace than standard keychain remotes and they typically need to be programmed by the dealer.

Some dealers charge up to $100 for a single smart fob. That's a huge sum to pay for something that is often time jostled around in purses and pockets, which is where it's easily damaged, dropped, or exposed to moisture and extreme temperatures. Fortunately, some automakers have developed ways to protect smart key fobs from the most common kinds of electronic attacks, such as relay attacks. These are usually employed in conjunction with remote-start hacks that allow thieves to access your vehicle's settings by transmitting false signals from a nearby transmitter.

To protect a smart fob you can put it in a metal case or use an RFID blocking case. This will stop the transmission of these signals. The convenience of this technology is compromised if have to remove your key fob every time you use it from the protective case.

Fortunately, some newer car-insurance policies such as auto club memberships and extended warranty coverages will pay for the cost of replacing a fob or pay for the loss of a fob. You can also avoid paying dealer fees by having your fob cloned at a hardware or locksmith store that offers key-fob-cloning.

The decision to purchase an additional fob is dependent on the importance of your car's keyless entry and start functions. You should always keep an extra key or fob in case you misplace yours. If you have to purchase a replacement, Batteries Plus has a wide selection of fobs for most cars and trucks. Plus, we offer a quick, convenient service that is roughly 50% less than you'd spend at the dealership.

Traditional Keys

The car key of old is a single piece of metal with a series of grooves carved into it. These grooves are made to fit certain locks. These van keys cut near me will open your locks and begin your car, provided you don't replace them with the remote key or smart key. The only disadvantage of using an old-fashioned car key is that you need to physically insert it into the ignition to start the engine. If your traditional key has been lost, damaged or stolen, you'll need to visit a Gainesville locksmith to get a new one made from the blank.

Based on the amount of time that has passed since the last time you had your keys cut, there are several different options available for you to choose from when it comes to having another copy. Some keys are cut using mechanical machines, while others are laser-cut with added security features.

Some of these modern features that come with the modern keys include encryption as well as other anti-theft mechanisms. Encryption makes it harder for thieves to duplicate keys or pick locks. Other anti-theft features include transponder chips, which are embedded into the keys to connect with your vehicle and allow it to work only when it's within a certain distance of your vehicle.

If you opt to use a traditional standard key, a locksmith could create a new one with a standard key cutting machine that can be found at many hardware stores. This is less expensive than using a key fob or a transponder key, and you'll still be able to operate your doors, locks and trunk.

Another alternative is to have the traditional car keys replaced with a laser cut version that has a unique pattern. The first time these keys were introduced was in the 1990s and are a popular choice for people who want to add extra protection to their vehicles. Keys made of lasers are typically equipped with transponder chips programmed to work only with your vehicle. If the chips aren't installed in your vehicle, it won't respond to the signals sent by the key.
