Car Key Cutting Explained Car key cutting is much more than simply shaping an object of metal. car keys cut is a complicated procedure that ensures safety, functionality and long-term use of keys. It is not unusual to lose keys to your car, or have them break in the lock. To ensure that you can always drive your car you'll need to have a replacement key cut. Transponder Keys Transponder chips are likely be installed in cars built in the last 20 years. These microchips are located in the key's handle and transmit a signal to your vehicle's onboard computers when you turn the key. The computer in the car reads the digital serial number in the chip and only allows the car to start if it is the correct one. This helps prevent theft of cars, as thieves would need to know your unique serial number to have a chance at hijacking it. The microchip in your car keys transmits an unintentional radio signal to the receiver inside the car. This radio signal activates the microchip, which transmits a code to the onboard computer of the car. The car will only begin only if it recognizes the code. This stops the use of “hot wiring” and other methods of taking cars. Car keys with chips can be made by locksmiths that offer these services. They are also available at some automotive retailers like AutoZone. They have a huge selection of keys, and can help you find the right one for your car. They can assist you in programming the chip in your vehicle that is required to operate the device. You can also get laser cut keys that are more secure than conventional flat keys. These keys feature an cylinder for locking that is much more difficult to pick, and they are only duplicated using expensive laser key cutting machines or special software. This technology is most common in high-end vehicles, but is now available on a variety of affordable models. The VATS (vehicle-anti-theft system) key is another type of key that's difficult to duplicate. These keys have a black resistor in the key blade that is programmed with one of 15 possible values to prevent them from starting a vehicle that it's not intended to. These keys are more expensive to buy and require a special key programming machine that can only be found at a few locksmiths. VATS Keys Before the days of transponder keys as well as cars equipped with computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key with a resistor pellet embedded in it to confirm that the correct key is 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 is merely a block or carbon that is sized to provide an electrical resistance value. GM employed 15 different resistance values for the VATS pellets and connected them to the blade of the key to ensure that, when the key is turned in the ignition, a coded signal is sent to the 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 burglar-proof, but it can delay thieves for at least 15 to twenty minutes. Unfortunately, after a lot of use, the VATS module in your car could begin to wear out. Every time a key is inserted into the ignition, it reroutes two small wires inside the ignition and over time the wires may begin to break. When enough wires break the signal to the module is lost and it won't start the car. The good news is that you can solve this issue at home by decoding your VATS key. You'll require a multimeter as well as a chart to find out the resistance value of your key, but it is not that difficult. You can find the resistance value by placing one of the leads on the prongs made of metal on both sides of your key. This method can also be a good method to test the new key to determine whether it works 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 vehicle. Smart Key Fobs Key fobs of today can do more than unlock or start a car. They can also be used as a security device and burglar deterrent, with a lot of them having advanced features that owners may not be aware of. They can remotely lock and unlock your doors, emit sounding sounds to help find your vehicle in a parking lot or let you summon your vehicle by pressing a button on your smartphone. This is more than you'd think of from a standard keychain remote. Smart key fobs are more expensive to replace because of their extra functions. They also require to be programmed at the dealer. In fact, some retailers will charge upwards of $100 to replace a single smart key fob. It's a huge cost to pay for a device that's often jostled in pockets and purses in the event that it gets 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. These are usually utilized in conjunction with remote-start hacks that allow thieves to gain access to the settings of your vehicle by sending false signals from a nearby transmitter. One method of protecting the key fob's RFID is to keep it in an aluminum 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 every time you use it undermines the convenience of the technology. Certain policies that are more recent, such as auto club memberships and extended warranties can cover the cost of replacing the fob or reimburse you if it gets lost. You can also save money on new car dealer charges and have your fob cut at a hardware store or locksmith who offers key fob cloning. The decision of whether to buy a new fob is dependent on the importance of your car's keyless start and entry functions. In any event you should have an extra fob or key in case in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit most cars and trucks. We also offer an efficient, quick service that is roughly 50% less than you'd spend at the dealership. Traditional Keys The classic car key is made of a single piece of steel with a series of grooves carved into it. These grooves are made to fit certain locks. These keys can open your locks and open the car, as long as you haven't exchanged them to a smart or remote key. The only drawback of using the traditional key is that it must be physically put into the ignition in order to start the vehicle. If your traditional key has been lost, damaged or stolen, you'll have to visit the Gainesville locksmith to have an alternative one cut from the blank. There are several options to select from based on how long it's been since you had your keys cut. Certain keys are cut using mechanical machines and others are laser-cut with added security features. Modern keys come with advanced features, such as encryption and anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or open locks. Transponder chips are another security feature that prevents theft. They are embedded 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, standard key, a locksmith could make a new one using a standard key cutter machine, which is available at many hardware stores. This is less expensive than a key fob or a transponder. you are still able to operate your trunk, locks, and doors. Another alternative is to get your standard car key substituted with a laser-cut version with a unique pattern. The first keys of this kind were released in the early 1990s and are a popular choice for those who wish to secure their vehicles. Typically, laser cut keys come with transponder chips that are designed to work only with your specific vehicle. If the chips aren't present in your car it won't receive the signals from the key and won't start.
