Car Key Cutting Explained Cutting keys for cars is more than just bending a piece metal. It is a complex process that ensures safety, functionality and long-term use of keys. It is not uncommon to lose your car keys or even have it break in the lock. To ensure that you are able to always drive your car you'll need a new key cut. Transponder Keys If your car was manufactured within the last 20 years, it is likely that it has transponder chips. These chips are small microchips in the handle of your key which transmit signals to the car's onboard computer when you use it. The onboard computer is able to verify the serial number of the chip before it allows the car to begin. This prevents thieves from hijacking your vehicle because they'd have to be aware of the unique serial number. The microchip in your car key sends an low-level radio signal to the car's receiver. This radio signal activates the microchip, and it then sends an encoded code to the car's onboard computer. The car will be able to recognize this code and only allow it to start only if the key is the correct one. This will stop the use of “hot wiring” and other methods of theft of cars. Locksmiths who offer these services can design car keys with chips. They are also available at certain automotive stores like AutoZone. These stores offer a wide selection of keys, and can help you find the best one for your vehicle. They can even assist you to program the chip to your vehicle, which is required for it to function. Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys due to the fact that they have locks that are harder to pick. They can only be duplicated with expensive laser key cutting equipment, or specialized software. This technology is more common in high-end vehicles, however it is now being used in a wide range of low-cost cars too. The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. The keys are black with a resistor in the key blade that is programmed with one of fifteen possible values to prevent them from starting a car that it's not intended to. These keys are more expensive to purchase and require a specific key programming machine that can only be found at a few locksmiths. VATS Keys Before transponder keys and cars with computers built-in to control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has an internal resistor to confirm that the right key was used to start the car. G28CarKeys that is in the center of a VATS key is not a chip like those used in modern smart keys, it is simply a block of carbon properly sized to carry an exact electrical resistance. GM employed 15 different resistance values for the VATS pellets. They attached the key's blade so that when the key is turned on the ignition the coded signal is sent to the module. If the signal matches the resistance value of the transistor in the VATS pellet, the relay in the starter circuit is activated and the engine begins to run. This doesn't make a car burglar-proof however, it can deter thieves for at least 15 to 20 minutes. After a lot of usage the VATS module could start to wear out. Each time the key is inserted into the ignition, it reroutes two small wires within the ignition, and, over time, the wires could begin to break. When enough wires are broken the signal to the module is lost and the module won't be able to start the car. You can solve this problem at home by decoding your VATS code. You'll require a multimeter and a chart to determine the resistance value of your key, but it is not difficult at all. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key. This is also a good way to test a new key to determine whether it will work in your car. Remove the ignition key first before you test it. In the event that it is not removed the key may have an incorrect VATS and will not work in your car. Smart Key Fobs Key fobs today are more than simply unlock or start the vehicle. They are also an alarm system and a security measure against theft, with many of them having advanced features that owners may not even be aware of. They can lock and unlock your door from a distance and emit chirping sounds to assist you in finding your car in a lot or summon it by pressing the button. This is more than you'd imagine from a traditional keychain remote. Unfortunately, all that extra capabilities also means that smart key fobs can be pricier to replace than standard keychain remotes and they typically require programming by the dealer. Some sellers charge as much as $100 for one smart fob. It's a high cost to pay for a device that is frequently tossed around in pockets and purses in the event that it gets damaged, thrown or exposed to extreme temperatures and moisture. Certain automakers have developed strategies to protect smart keyfobs from common electronic attacks, like relay attacks. These are often employed in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting a fake signal from another nearby transmitter. To safeguard a smart fob you can put it in a casing made of metal or use an RFID blocking case. This will stop the transmission of these signals. However, the necessity of removing the key fob from a case that is protected each time you want to use it undermines the convenience of the technology. Fortunately, a few of the latest car insurance policies, auto club memberships, and extended warranty coverages will pay for the cost of replacing a fob or reimburse you for the lost fob. You can also avoid paying dealer fees by having your fob copied at a locksmith or hardware store that offers key-fob-cloning. For the majority of drivers, the decision to purchase an additional key fob is contingent on how crucial your car's keyless entry and push-button start functions are. In any event it is advisable to keep a spare fob or key in case you lose it. Batteries Plus offers a large choice of replacement fobs that fit most cars and trucks. Additionally, our fast and efficient service is 50% less than what you'd buy from a dealership. Traditional Keys Traditional keys for cars are a single piece of metal with grooves cut into it to fit into a particular lock. These keys will unlock your locks and open the car, provided you haven't exchanged them for a smart key or remote key. The only drawback to using a traditional key is that it has to be physically put into the ignition to start the vehicle. If your car key is lost or broken it is necessary to visit a Gainesville locksmith to get a new one created. Depending on how much time has passed since the last time you cut your keys, there are several different options to select from when it comes time to get another copy. Certain keys utilize mechanical cutting machines to make copies, whereas others use laser-cut keys specifically designed with enhanced security features in mind. Modern keys come with advanced features, such as encryption and anti-theft mechanisms. Encryption makes sure that only the correct key can be used to open your vehicle which makes it harder for thieves to duplicate keys or pick locks. Transponder chips are a different security feature that prevents theft. They are embedded in the key and can communicate with your vehicle. This means that they only effective only when you're within a specific distance. If you decide to utilize a traditional key your locksmith can make an entirely new key using a standard cutter machine that is available from a variety of hardware stores. This is cheaper than a key fob, or a transponder, and you will still be able to use your locks, trunk, and doors. You can also replace your traditional car keys with a laser-cut version with a unique pattern. These keys were introduced in the 1990s and are a popular option for those looking to protect their vehicles. The majority of laser cut keys have special transponder chips that are specifically programmed to work with your specific vehicle. If the chips aren't present in your vehicle, it won't respond to the signals from the key and won't start.
