Car Key Cutting Explained Cutting the car key is more than just bending a piece metal. It is a sophisticated procedure that ensures security, efficiency and long-term use of the keys. It is not uncommon to lose your car keys or have them break through the lock. You will need a new car key in order to ensure you can drive your vehicle at all times. Transponder Keys Transponder chips will likely be added to cars that were built in the last 20 years. These microchips are tiny located in the handle of your key that transmit a signal to the vehicle's onboard computer when you are using it. The onboard computer checks the serial number digitally of the chip prior to allowing the car to start. This prevents thieves from taking over your vehicle since they'd need to be aware of the unique serial number. The microchip inside your car key sends an low-level radio signal to the receiver inside the car. The radio signal activates microchip, which transmits an informational code to the car's onboard computer. The car will be able to recognize the code and only allow it to start when the key is the correct one. This stops the use of “hot wiring” and other methods of theft of cars. Car keys with chips can be made at a locksmith that offers these services. They can also be bought at some automotive retailers like AutoZone. They have a huge variety of keys, and can assist you in choosing the best one for your car. They can also help you program the chip to your vehicle, which is necessary for it to function. Laser cut keys are more secure than flat keys. These keys have the lock cylinder, which is much more difficult to pick, and are only duplicated using expensive laser key cutting machines or special software. This technology is most commonly found in high-end cars however, it is now available on a variety of affordable models. Another type of key for cars that is difficult to duplicate is the VATS (vehicle anti-theft system) key. 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 meant to. They are expensive and require the use of a key programming machine which is only available at a few locksmiths. Keys to VATS Before transponder keys and cars that had computers built-in to control the ignition, GM used a system 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 black VATS Pellet located in the middle of a VATS Key isn't a smart chip as found on most modern keys. It's just carbon or a block that is sized to hold an electrical resistance value. GM used 15 different resistance values for the VATS pellets. They attached them to the key's blade to ensure that, when the key is turned in 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 starts to run. This doesn't make a vehicle safe from theft however it can delay the theft by at minimum 15 to 20 minutes. After a long period of use the VATS module may begin to wear out. Each time the key is inserted into the ignition, it moves two tiny wires inside the ignition and with time, the wires can begin to break. Once enough wires are broken, the signal to the module is not received and it will not start the car. The good news is that you can fix this issue at home by decoding your own VATS key. It's not hard to determine the resistance value of a key with the multimeter. 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 can also be a good method to test a new key to determine whether it will work in your car. Remove the key from the ignition first before you test it. Otherwise the key could have an incorrect VATS, 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 car. They also function as used as a security device and security measure against theft, with many of them incorporating advanced features that owners might not be aware of. They can lock and unlock your door remotely and emit chirping sounds to help you locate your vehicle when you're in a hurry or summon it by pressing the button. That's a lot more than you'd imagine from a traditional keychain remote. Unfortunately, all that added functionality also means that smart key fobs could be pricier to replace than standard keychain remotes and they typically need to be programmed by the dealer. Some dealers will charge up to $100 for a single smart fob. It's a steep cost to pay for a device that's often tossed around in pockets and purses where it can be damaged, dropped or exposed to extreme temperatures and moisture. Some automakers have developed methods to shield smart key fobs from common electronic attacks, like relay attacks. key cut places near me are typically combined with a remote start hack that gives thieves access to your vehicle's settings by the transmission of a fake signal another transmitter close to. One way to protect a smart key fob is to store it in a metal case or use an RFID blocking case that prevents the transmission of these signals. However, having to take the key fob from its protective case each time you use it is not a good way to enjoy the benefits of the technology. Some of the newer policies like auto club memberships and extended warranties will cover the cost of replacing the fob or reimburse you in the event that it gets lost. You can also save money on dealer charges and have your fob cut at an establishment like a locksmith or hardware store which offers key-fob cloning. For the majority of drivers, the decision to purchase an extra key fob will depend on how important your car's keyless entry and push-button starter functions are. In any event it is advisable to keep an extra fob or key in case in case you lose yours. And if you need to buy a new replacement, Batteries Plus has a large selection of fobs to fit the majority of cars and trucks. We also offer an efficient, quick service that is roughly 50% less than what you'd spend at the dealership. Traditional Keys Traditional car keys are a single length of steel that has a series of grooves cut into it to fit into a particular lock. They can unlock your locks and start your car, assuming you don't replace them with the remote key or smart 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 lost, broken or stolen, you'll need to visit an Gainesville locksmith to have a new one made from the blank. You have a few choices to pick from based on how long it has been since you've cut your keys. Certain keys are cut with mechanical machines and others are laser-cut with enhanced security features. Modern keys are equipped with advanced features such as encryption and anti-theft mechanisms. Encryption ensures that only the correct key can be used to start your vehicle which makes it harder for thieves to duplicate keys or pick locks. Other anti-theft features include transponder chips that are incorporated into the key to communicate with your car and make it work only when it's within a certain range of your car. If you opt to use a traditional key, your locksmith can create the new key using a standard cutter machine that is available from most hardware stores. This is less expensive than the key fob or transponder key, and you'll be able to operate your locks, doors and trunk. You could also replace your traditional keys for your car with a laser cut version that has an unique pattern. These keys first came out in the late 1990s, and are a popular choice for those looking to enhance the security of their automobiles. Typically, laser cut keys contain transponder chips that are designed to work only with your specific vehicle. If these chips aren't installed in your car it won't be able to respond to the signals coming from the key, and will not start.
