Car Key Cutting Explained Cutting the car key is more than just bending a piece of metal. It is a complex process that guarantees security, functionality and the longevity of keys. It is not uncommon to lose your car key or even have it break in the lock. You'll require a new car key in order to ensure you can drive your vehicle at all times. Transponder Keys Transponder chips will likely be fitted in vehicles built within the past 20 years. These microchips are in the handle of the key and transmit a signal the onboard computers of your vehicle when you turn the key. The computer in the car scans the digital serial numbers inside the chip and allows the car to start if it is the right one. This prevents car theft since thieves need to know your unique serial number to be able to steal it. The microchip inside your car keys transmits an low-level radio 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 recognize this code and will only allow it to start if the key is the correct one. This prevents “hot wiring” or other methods of stealing cars. auto key cutting that offer these services can make keys for cars with chips. They can also be bought at certain automotive stores, such as AutoZone. They have a huge selection of keys, and can help you find the best one for your car. They can even assist you to programme the chip into your vehicle, which is necessary to make it work. Laser cut keys are more secure than flat keys. They are more secure than flat keys due to the fact that they have locks that are harder to pick. They can only be duplicated using expensive laser key cutting machines or specialized software. This type of technology is typically found in high-end vehicles but is now accessible on a variety of affordable models. The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. These keys feature a black resistor on the key blade that is programmed with one of fifteen possible values to prevent them from starting a car that it's not designed to. These keys are more expensive to purchase and require a specific key programming machine that is only located at certain locksmiths. VATS Keys Before the advent of transponder keys and automobiles with built-in computer chips to control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS utilizes a key that has a resistor embedded in it to ensure that the correct key was used to start the car. The VATS black pellet that is in the center of the VATS key isn't an electronic chip like the ones 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 the VATS Pellets. They attached them to key blades in a way that, when the key was turned on, the key blades transmit a coded message 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 vehicle secure from theft however it can delay the theft by at most 15 to 20 minutes. Unfortunately, after a lot of usage, the VATS module in your car could begin to wear out. The two small wires in the ignition are moved every time a key is placed. Over time, the wires may begin to break. Once enough of the wires break then the signal to the module gets lost and it won't start the car. You can solve this problem at home by decoding your VATS code. It's not hard to determine the resistance of a key using the multimeter. You can determine the resistance value by putting one of the leads on the prongs of metal on both sides of your key. This is a great way to test a new key and see if it works in your car. Be sure to remove the key from the ignition before you begin testing it, as the new key may have an incorrect VATS number and will not work in your car. Smart Key Fobs with Smart Keys Key fobs today can do more than simply unlock and start the vehicle. They are also used as a security device and security measure against theft, with many of them featuring advanced features that owners might not be aware of. They can remotely lock and unlock your doors, make sounding sounds to help find your car in a parking lot or allow you to summon your vehicle by pressing the button on your smartphone. This is more features than you get from a traditional keychain remote. Unfortunately, all that added functionality can mean that smart key fobs may be pricier to replace than standard keychain remotes. They also need to be programmed by the dealer. In fact, some retailers will cost upwards of $100 to replace one smart key fob. It's a huge price to pay for a device that's often tossed around in pockets and purses where it could be damaged, thrown or exposed to extreme temperatures and moisture. Fortunately, some automakers have developed ways to safeguard smart key fobs from common types of electronic threats like relay attacks. They are typically employed in conjunction with remote-start hacks that allow thieves to access the settings of your vehicle by sending a fake signal from another nearby transmitter. One method to safeguard the smart key fob is to put it in a metal case or a dedicated RFID blocking case that blocks the transmission of these signals. The convenience of this technology is compromised if need to remove your key fob each time you use it from the protective case. Fortunately, some of the newer car insurance policies, auto club memberships, and extended warranty insurance policies will cover the cost of a replacement or reimburse you for the lost fob. You can also avoid paying new-car dealership fees by having your fob cloned by a locksmith or hardware retailer that provides key-fob cloning. For most drivers who are buying an additional key fob is contingent on how important your car's keyless entry and push-button start functions are. In any event you should have a spare key or fob handy just in case you lose yours. Batteries Plus offers a large choice of replacement fobs that fit on most cars and trucks. Additionally, our fast and convenient service costs about 50% less than what you would buy from the dealership. Traditional Keys The classic car key is a single piece of metal with a series of grooves carved into it. These grooves are made to fit specific locks. These keys can open your locks and also start the car, assuming you haven't exchanged them to a smart or remote key. The only disadvantage of using a traditional key is that it has to be physically placed into the ignition to start the vehicle. If your traditional key is damaged, lost or stolen, you'll need to visit a Gainesville locksmith to get a new one made from the blank. Depending on how much time has passed since the last time you got your keys cut there are a variety of options to select from when it comes to getting another copy made. Certain keys employ mechanical cutting machines to create copies, while others employ laser-cut keys that have been made with security features in mind. Modern keys are equipped with advanced features like encryption and anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or take locks. Transponder chips are another security feature that prevents theft. They are embedded into the key and can communicate with your vehicle. This means that it can only function only when you're within a specific distance. If you choose to make use of a traditional key, your locksmith can design a new key with an ordinary cutter machine that is available from a variety of hardware stores. This is cheaper than using a key fob or a transponder key, and you'll still be able to use your doors, locks and trunk. Another alternative is to get the traditional car keys substituted with a laser-cut version that has a unique pattern. The first time these keys were introduced was in the late 1990s, and are now a popular option for those who wish to provide extra security to their automobiles. Keys made of lasers are typically equipped with transponder chips that are programmed to only work with your vehicle. If these chips aren't present in your car it won't receive the signals coming from the key and won't start.
