Car Key Cutting Explained Cutting a car key is more than just bending metal. It is a complex process that guarantees safety, functionality and long-term use of the keys. It is not uncommon to lose your car key or have it break off in the lock. To ensure that you are able to always drive your car you'll require a replacement key cut. Transponder Keys Transponder chips are likely to be added to cars that were built in the last 20 years. These chips are tiny microchips located in the handle of your key that transmit signals to the car's onboard computer when you are using it. The computer in the car detects the digital serial number in the chip and only allows the car to start if it's the correct one. This helps prevent theft of cars, as thieves would need to know your unique serial number in order to be able to steal it. The microchip in your car keys transmits an low-level radio signal to the receiver inside the car. The radio signal activates your microchip, which transmits a code to the onboard computer of the car. The car will only begin if it recognizes this code. This prevents the use of “hot wiring” and other methods of stealing cars. Car keys with chips can be made by a locksmith that offers these services. They are also available at a few automotive stores like AutoZone. They have a vast variety of keys and can help you get the right one for your vehicle. They can also help you programme the chip into your vehicle, which is necessary for it to function. There are also laser cut keys that are more secure than traditional flat keys. They are more secure than traditional flat keys due to the fact that they have locks that are more difficult to pick. They can only be duplicated using expensive laser key cutting machines or specialized 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 is difficult to duplicate. These keys come with a resistor black on the blade of the key. G28 Car Keys can be programmed to one of 15 possible values to prevent it from starting a vehicle it's not intended to. These keys are more expensive to purchase and require a special key programming machine that can only be found at a few locksmiths. VATS Keys Before the advent of transponder keys and cars equipped with computer chips to control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS makes use of a key with an internal resistor to verify that the correct key was used to start the car. The black VATS Pellet in the middle of a VATS Key isn't a smart chip as used on the majority of modern keys. It is simply carbon or a block that is sized to hold an electrical resistance value. GM used 15 different resistances for the VATS Pellets and connected the key blades to them so that when the key is turned in the ignition the key blades transmit a coded message to 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 theft proof however it will delay the thief by at minimum 15 to 20 minutes. Unfortunately, after a significant amount of usage, the VATS module in your car could start to wear out. The two wires that connect the ignition move each time the key is inserted. Over 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 start. You can solve this problem at home by decoding your VATS code. It's not difficult to determine the resistance of a key using a multimeter. All you have to do is put one of the leads of your ohm gauge on the metal prongs that are sticking out on both sides of the key, and then read the ohm meter's display to determine the resistance of your key. This is a great opportunity to test a new key and determine whether it will work in your car. Make sure you remove the key from the ignition prior to testing it, or else the new key could have an incorrect VATS value and not work in your car. Smart Key Fobs for Keys Key fobs today are more than just a way to unlock or start a car. Many of them have advanced features that a lot of owners are not aware of. They can be used as a security device or as a deterrent to theft. They can lock and unlock your door from a distance, make chirping noises to aid in locating your car in a lot or summon it by pressing the button. This is more functionality than you get from a traditional keychain remote. Smart key fobs are more expensive to replace because of their additional functions. They also require to be programmed by the dealer. Some sellers charge as much as $100 for a single smart fob. It's a steep price to pay for a device that is often jostled in pockets and purses in the event that it gets damaged, dropped or exposed to extreme temperatures and water. Some automakers have developed methods to protect smart keyfobs from common electronic attacks, such as relay attacks. These are often combined with a remote start hack that gives thieves access to your vehicle's settings by the transmission of a fake signal another transmitter near. One method to safeguard the smart key fob is to store it in an aluminum case or an RFID blocking case that prevents the transmission of these signals. However, having to take the key fob from its case that is protected each time you make use of it is a hassle and a detriment to the efficiency of the technology. Some of the newer policies like auto club memberships or extended warranties can pay for an additional fob, or reimburse you if it gets lost. You can also save money on new-car dealer charges and have your fob cut at the hardware store or locksmith who offers key fob cloning. The decision of whether to buy a new fob is largely based on the importance of your car's keyless start and entry functions. It is always advisable to keep an extra key or fob on hand in case you misplace yours. If you do need to purchase a new replacement, Batteries Plus has a wide selection of fobs for the majority of vehicles and trucks. In addition, our quick and convenient service costs about 50% less than what you would pay at the dealership. Traditional Keys The traditional car key is made of a single piece of steel with a series of grooves carved into it. These grooves are designed to fit certain locks. These keys will open your locks and start your car, provided you haven't replaced them with the remote key or smart key. The only downside of using an old-fashioned car key is that you have to physically insert it into the ignition to start the engine. If your key from the past is lost, broken or stolen, you'll need to visit the Gainesville locksmith to have a new one cut from the blank. Based on the amount of time that has passed since the last time you had your keys cut there are a variety of alternatives to pick from when it comes to having another copy. Some keys are cut using mechanical machines or lasers, while others are cut with added security features. Modern keys have advanced features like encryption and anti-theft mechanisms. Encryption ensures that only the right key can be used to open your vehicle making it much more difficult for thieves to duplicate keys or pick locks. Transponder chips are a different anti-theft feature. They are incorporated into the key and communicate with your vehicle. This makes it only effective only when you're within a specific distance. If you choose to use a traditional, standard key, a locksmith could make a new one with a standard key cutting machine, which is available at most hardware stores. This is less expensive than a key fob, or a transponder, and you are still able to operate your trunk locks, trunk locks and doors. You can also replace your standard keys to your car 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 option for those who wish to protect their vehicles. Laser cut keys are usually equipped with transponder chip that is programmed to only work with your vehicle. If these chips are not present in your vehicle, it will not respond to the signals transmitted by the key.
