Car Key Cutting Explained Car key cutting is a lot more than simply shaping an object of metal. It is a complex process that guarantees security, function and longevity of keys. It is not unusual to lose your car keys or have them break through the lock. To ensure that you are able to always drive your vehicle you'll require a replacement key cut. Transponder Keys Transponder chips are likely to be added to cars that were that were built in the last 20 years. These microchips are tiny inside the handle of your key which transmit signals to the car's onboard computer when you use it. The onboard computer checks the serial number digitally of the chip prior to giving the car permission to start. This prevents thieves from hijacking your vehicle, as they would need to be aware of 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 microchip, which then transmits an informational code to the car's onboard computer. The car will be able to recognize this code and will only allow it to start if it is the correct one. laser key cutting g28carkeys stops the use of “hot wiring” and other methods of stealing cars. Car keys with chips can be made at a locksmith that offers these services. Some automotive retailers such as AutoZone offer keys with chips. These stores offer a wide variety of keys, and can help you find the best one for your car. They can even help you programme the chip into your vehicle, which is necessary to make it work. Laser cut keys are more secure than flat keys. These keys feature an cylinder for locking that is much harder to pick, and 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, however it is now available in many affordable models of automobiles as well. Another kind of car key that's difficult to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the blade of the key that is programmed with one of 15 possible values to prevent them from starting a car that it's not intended to. These keys are more expensive to buy and require a specific key programming machine that can only be found at a few locksmiths. VATS Keys Before transponder keys and vehicles with computer chips 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 ensure that the correct key was used to start the car. The VATS black pellet that is inside the middle of the VATS key isn't an electronic chip like the ones used in modern smart keys, it is simply a piece of carbon that is sized appropriately to have an exact electrical resistance. GM employed 15 different resistances for the VATS Pellets. They attached them to key blades in a way that, when the key was turned on, a coded message is sent to module. If the signal is in line with the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine will start to run. This doesn't make a car secure from burglary however, it can deter thieves for at least 15 to twenty minutes. Unfortunately, after a lot of use, the VATS module in your car may start to wear out. Each time the key is inserted into the ignition it moves two very small wires inside the ignition and, over time, the wires may begin to break. When enough wires have been broken, the signal is lost to the module and the car will not start. The good news is that you can fix this issue yourself 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. 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. Then examine the display of your ohm meter to find out 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. Make sure you remove the key from the ignition before you begin testing it, otherwise the new key may have an incorrect VATS number and will not function in your car. Smart Key Fobs for Keys Key fobs today can do more than simply unlock and start the vehicle. They are also used as a security device and theft deterrent, with many of them having advanced features that owners might not even know about. They can remotely lock and unlock your doors, make sounding sounds to help locate your car in a parking space and even allow you to call your vehicle by pressing a button on your smartphone. This is more functionality than you get from a traditional keychain remote. Smart key fobs are more expensive to replace due to their additional functions. They also have to be programmed at the dealer. Some sellers charge as much as $100 for a single smart fob. It's a high price to pay for a device that's frequently tossed around in pockets and purses where it could be damaged, dropped or exposed to extreme temperatures and humidity. Some automakers have developed methods to protect smart keyfobs from common electronic attacks, such as relay attacks. These are often employed in conjunction with remote-start hacks that allow thieves to access your vehicle's settings through an untrue signal from a nearby transmitter. To safeguard a smart fob you can put it in a metal casing or use an RFID blocking case. This will stop the transmission of these signals. However, having to take the key fob from its protective case each time you use it undermines the convenience of the technology. Fortunately, a few of the latest car insurance policies and auto club memberships and extended warranty coverages will pay for the cost of a replacement or reimburse you for a lost fob. You can also avoid paying dealership fees by having your fob cloned at a hardware or locksmith store that offers key-fob-cloning. For most drivers who are buying a new key fob depends on how important your car's keyless entry and push-button starter functions are. In any case, you should always have an extra fob or key in case in case you lose it. If you have to purchase a replacement, Batteries Plus has a wide selection of fobs for the majority of vehicles and trucks. In addition, our quick and efficient service is 50% less than the price you would pay at the dealership. Traditional Keys The traditional car key is a single piece of metal with a series of grooves cut into it. These grooves are made to fit specific locks. These keys will open your locks and begin your car, provided you haven't replaced them by a 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 car key is lost or broken it is necessary to visit the Gainesville Locksmith to get a new one made. There are several choices to pick from based on how long it has been since you've had your keys cut. Some keys use mechanical cutting machines to make copies, whereas others use laser-cut keys designed with enhanced security features in mind. Some of these advanced features that come with modern-day keys include encryption and other anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or take locks. Other security features that prevent theft include transponder chips that are incorporated into the key to connect with your car and make it only function when it's within a certain distance of your car. If you opt to use a traditional standard key, a locksmith could create a new one using a standard key cutter machine which can be purchased at many hardware stores. This is cheaper than using the key fob or transponder key, and you'll still be able to operate your locks, doors and trunk. You could also replace your traditional keys to your car with a laser-cut version that has an unique pattern. These keys were first introduced in the 1990s, and are a popular choice for those who wish to add extra protection to their automobiles. Keys made of lasers are typically equipped with transponder chips that are programmed to only work with your vehicle. If the chips aren't installed in your vehicle, they will not respond to the signals transmitted by the key.
