Car Key Cutting Explained Car key cutting is more than just forming the metal. It is a complex process that guarantees security, function and durability of keys. It is not uncommon to lose your car keys or even have them break into the lock. You will need an alternative car key to ensure that you can drive your vehicle at all times. Transponder Keys If your car was manufactured in the past 20 years, it is likely that it has transponder chips. car key cutting and programming are located in the key's handle and transmit a signal to the onboard computers in your vehicle when you press the key. The computer in the car examines the serial number of the chip before it allows the car to start. This helps prevent theft of cars as thieves would have to know your unique serial number to be able to steal it. The microchip in the key transmits a low-level signal to the car's receiver. The radio signal activates your microchip that then transmits the instructions to the onboard computer of the car. The car will only start only if it recognizes the code. This will stop the use of “hot wiring” and other methods of theft of cars. Car keys with chips can be created at locksmiths that offer these services. They can also be purchased at certain automotive stores like AutoZone. Those stores carry a huge variety of keys and can help you get the right one for your car. They can even help you programme the chip into your vehicle, which is necessary for it to function. Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys because they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting machines, or specialized software. This type of technology is typically found in luxury vehicles, but it is now being used in many affordable models of cars too. Another type of key for cars that is 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 fifteen potential values to prevent them from starting a vehicle that it's not designed to. They are expensive and require a key programming machine, which is only available through certain locksmiths. Keys to VATS Before transponder keys and cars with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS uses a key with a resistor embedded in it to ensure that the correct key was used to start the car. The VATS black pellet that is inside the middle of a VATS key is not an electronic chip as found on modern smart keys, it's simply a carbon block properly sized to carry an electrical resistance that is specific to. GM used 15 different resistances for VATS pellets and attached them to key blades so that when the key was turned on, the key blades transmit a coded message to the module. If the signal is in line with the signal of the transistor in a VATS pellet, then the relay in starter circuit will activate and the engine will start to run. This isn't a way to make a car theft proof however it will delay the thief by at least 15 to 20 minutes. Unfortunately, after a long period of use, the VATS module in your car could begin to wear out. Every time a key is inserted into the ignition, it moves two very small wires inside the ignition and with time, the wires may begin to break. When enough wires have been broken the signal goes out to the module and the car won't begin. You can solve this problem at home by decoding your VATS code. It's not difficult 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 a great opportunity to test a brand new key and see whether it works in your vehicle. Make sure you remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS value and not function in your car. Smart Key Fobs with Smart Keys Key fobs today are more than simply unlock or start the car. They are also a security device and a burglar deterrent, with a lot of them having advanced features that the owners might not even know about. They can remotely lock and unlock your doors, emit chirping sounds to help you find your vehicle in a parking lot or let you summon your vehicle by pressing a button on your smartphone. This is a lot more features than you get from a traditional keychain remote. Unfortunately, all that extra features can mean that smart key fobs may be more expensive to replace than standard keychain remotes and they typically require programming by the dealer. Some sellers charge as much as $100 for a single smart fob. That's a lot to pay for something that spends much of its time snagging around in pockets and purses, where it is easily dropped, damaged or exposed to extreme humidity and temperatures. Fortunately certain automakers have come up with methods to shield smart key fobs from the most common types of electronic threats like relay attacks. These are usually used in combination with remote-start hacks that allow thieves to access your vehicle's settings by transmitting a fake signal from another nearby transmitter. To secure a smart card to protect it, you can place it in a metal case or even 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 need to use it is not a good way to enjoy the benefits of the technology. Some of the newer policies like auto club memberships or extended warranties will pay for a replacement fob or reimburse you in the event that it gets lost. You can also avoid paying dealership fees by having your fob copied by a locksmith or hardware retailer that provides key-fob cloning. For the majority of drivers who want to buy an additional key fob is contingent on how crucial your car's keyless entry and push-button start functions are. In any case you should have a spare fob or key in case in case you lose yours. Batteries Plus offers a large selection of replacement fobs that fit on most cars and trucks. Additionally, we provide an efficient, quick service that is roughly 50% less than you'd spend at the dealership. Traditional Keys Traditional keys for cars are a single piece of metal that has grooves cut into it to fit a specific lock. These keys will unlock your locks and start the car, provided you don't swap them out for a smart key or remote key. The only drawback to using an old-fashioned car key is that you have to physically insert it into the ignition to start the engine. If your traditional key has been damaged, lost or stolen, you'll need to visit the Gainesville locksmith to have new keys cut from the blank. Based on the amount of time that has passed since you last cut your keys There are many options available for you to pick from when it comes to getting another copy made. Certain keys are cut with mechanical machines or lasers, while others are cut with security features that are enhanced. Modern keys come with advanced features like encryption and anti-theft mechanisms. Encryption makes it harder for thieves to duplicate keys or take locks. Other security features that prevent theft include transponder chips, which are embedded into the keys to connect with your car and make it only function when it's within a certain range of your car. If you choose to use a conventional, standard key, a locksmith could make a new one using a standard key cutter machine that can be found at most hardware stores. This is less expensive than a key fob, or transponder, and you can still operate your trunk locks, trunk locks, and doors. Another option is to have the traditional car keys replaced with a laser-cut version with a distinctive pattern. These keys were first introduced in the late 1990s, and they're a popular choice for those looking to enhance the security of their automobiles. Keys made of lasers are typically equipped with transponder chips programmed to only work with your vehicle. If the chips aren't present in your vehicle, it won't respond to the signals generated by the key.
