Car Key Cutting Explained Car key cutting is more than just forming the metal. It is a complicated procedure that ensures security, efficiency and the longevity of keys. It is not unusual to lose keys to your car, or have them break in the lock. You'll need a new car key in order to ensure that you can drive your vehicle at all times. Transponder Keys Transponder chips are likely to be fitted in vehicles built within the past 20 years. These microchips are tiny in the key's handle that send a signal to the vehicle's onboard computer whenever you use it. The computer on board reads the digital serial number in the chip and only allows the car to start if it's the correct one. This prevents car theft as thieves would have to know your unique serial number to be able to take over it. The microchip in the key transmits a low-level signal the car's receiver. This radio signal activates the microchip, which then transmits an encoded code to the car's onboard computer. The car will only begin when it recognizes the code. This prevents the use of "hot wiring" and other methods of stealing cars. Locksmiths who offer these services can make keys for cars that contain chips. Some car dealers, like AutoZone offer them. These stores have a wide variety of keys and can assist you in choosing the appropriate one for your car. They can assist you in programming the chip in your vehicle that is required for the device to function. There are also laser cut keys, which are more secure than conventional flat keys. These keys have a lock cylinder that is much harder to pick, and they are only duplicated using expensive laser key cutting machines or specially designed software. This type of technology is typically found in high-end vehicles, but is now available in a wide range of low-cost models. The VATS (vehicle-anti-theft system) key is a different type of key that is difficult to duplicate. They come with a resistor black on the blade of the key. It can be programmed to one of a variety of values to prevent it from starting a car that's not designed to. These keys are more expensive to buy and require a specific key programming machine that can only be found at some locksmiths. VATS Keys Before transponder keys and cars with computer chips that control the ignition, GM used a system called VATS (Vehicle Anti-Theft System). VATS utilizes a standard key with a resistor pellet embedded within it to verify that the correct key is used to start the car. The VATS pellet black inside the middle of the VATS key isn't an electronic chip like the ones present in modern smart keys. It is simply a piece of carbon appropriately sized to have a specific electrical resistance value. GM used 15 different resistances for the VATS Pellets and connected the key blades to them so that when the key was turned in the ignition the key blades transmit a coded message to the module. If it matches the resistance value of the transistor in the VATS pellet the relay in the starter circuit is activated and the engine will start to run. This doesn't make a car safe from burglary, but it can delay the thief for a minimum of fifteen to twenty minutes. Unfortunately, after a lot of use, the VATS module in your car can begin to wear out. The two wires that connect the ignition are moved every time a key is introduced. Over time, the wires may start to break. Once enough of car key cutting near me break, the signal to the module is lost and the module won't be able to start the car. You can resolve this issue at home yourself by decoding your VATS key. It's not difficult to determine the resistance value of a key by using a multimeter. All you need 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 find out the resistance value of your key. This is also a good way to test a new key to determine whether it will work in your vehicle. Remove the ignition key first before you test it. If not the key could have an incorrect VATS, and will not work in your vehicle. Smart Key Fobs with Smart Keys Key fobs today do more than just unlock or start the vehicle. They often have advanced features that many owners are unaware of. They can be used as a security device or a theft deterrent. They can lock and unlock your door remotely, make chirping noises to help you locate your vehicle when you're in a hurry, or allow you to summon it by pressing a button. This is more functionality than you get from a traditional keychain remote. Smart key fobs are more expensive to replace because of their extra functions. They also require to be programmed at the dealer. Some sellers charge as much as $100 for a single smart fob. That's a huge sum to pay for a product that is often time snagging around in pockets and purses, where it is easily dropped, damaged or exposed to extreme moisture and temperatures. Some automakers have developed methods to protect smart keyfobs from common electronic attacks, such as relay attacks. These are usually used in combination with remote-start hacks that allow thieves to access your vehicle's settings by transmitting an untrue signal from a nearby transmitter. To secure a smart card, you can store it in a metal casing or even an RFID blocking case. This will block the transmission of these signals. The convenience of the technology is diminished if you have to remove your key fob each time you use it from the case. Fortunately, a few of the latest car insurance policies and auto club memberships and extended warranty coverages will cover the cost of a replacement or pay for the loss of a fob. You can also avoid paying new-car dealer fees by having your fob copied at a locksmith or hardware retailer that provides key-fob cloning. For the majority of drivers, the decision to purchase an additional key fob is contingent on the importance of your car's keyless entry and push-button starter functions are. You should always keep a spare key or fob on hand in case you lose yours. If you do need to buy a new replacement, Batteries Plus has a large selection of fobs to fit the majority of vehicles and trucks. Additionally, we provide an efficient, quick service that is roughly 50% less than what you'd pay at the dealership. Traditional Keys Traditional keys for cars are a single piece of steel that has a series of grooves cut into it to fit into a particular lock. These keys can unlock your locks and start your car, assuming you haven't replaced them with an electronic key or a remote key. The only disadvantage of using the traditional key is that it has to be physically put into the ignition to start the vehicle. If your traditional car key has been damaged or lost, you will need to visit a Gainesville Locksmith to get a new one made. Based on the amount of time that has passed since the last time you got your keys cut There are many options to pick from when it comes to having another copy made. Certain keys are cut using mechanical machines, while others are laser-cut with enhanced security features. Some of these features that are included in modern types of keys include encryption and other anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or pick locks. Transponder chips are another anti-theft feature. They are embedded in the key and can communicate with your vehicle. This makes it only work when you're within a certain distance. If you choose to make use of a traditional key, your locksmith can make a new key with an ordinary cutter machine, which can be purchased at most hardware stores. This is cheaper than a key fob, or transponder, and you are still able to operate your trunk, locks and doors. You can also replace your standard car keys with a laser-cut version that has an unique pattern. These keys first came out in the 1990s, and are a popular choice for people who want to add extra protection to their vehicles. Typically, laser cut keys come with transponder chips that are designed to work only with your specific vehicle. If the chips aren't installed in your vehicle, they will not respond to the signals generated by the key.
