Car Key Cutting Explained Car key cutting is much more than simply shaping an object of metal. It is a complicated procedure that ensures security, functionality and durability of keys. It is not unusual to lose keys to your car, or even have them break into the lock. To ensure you're able to always drive your vehicle, you will need a new key cut. Transponder Keys Transponder chips will likely be added to cars that were built within the past 20 years. These chips are small microchips in the handle of your key that transmit signals to the car's onboard computer when you use it. The onboard computer detects the digital serial number within the chip and allows the car to start if it's the correct one. This helps prevent theft of cars since thieves need to know your unique serial number to be able to take over it. The microchip in the key sends a low-level signal the receiver within the car. The radio signal activates your microchip, which transmits a code to the onboard computer of the car. The car will recognize the code and only allow it to start when it is the correct one. This prevents “hot wiring” or other methods to steal cars. Locksmiths that offer these services can create keys for cars that contain chips. Some automotive retailers such as AutoZone offer keys with chips. These stores offer a wide selection of keys, and can help you find the appropriate one for your vehicle. They can even assist you to program the chip to your vehicle, which is required to make it work. 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 more difficult to pick. They can only be duplicated with expensive laser key cutting equipment, or specialized software. This technology is more prevalent in high-end vehicles, however it is now being used in a variety of affordable cars as well. Another kind of car key that's hard to duplicate is the VATS (vehicle anti-theft system) key. These keys have a black resistor on the key blade that is programmed with one of fifteen possible values to stop them from starting a car that it's not meant to. These keys are more expensive to buy and require a specific key programming machine that is only located at certain locksmiths. VATS Keys Before the days of transponder keys and automobiles equipped with computer chips that control the ignition of a car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses a key with an embedded resistor to ensure that the correct key was used to start the car. The VATS black pellet that is in the center of a VATS key is not a chip like those found on modern smart keys, it is simply a piece of carbon properly sized to carry an exact electrical resistance. GM used 15 different resistances for VATS pellets and attached them to key blades so that, when the key was turned in the ignition a coded signal is sent to the module. If cut car key near me matches the one of the transistors in a VATS pellet then the relay in the starter circuit will activate and the engine will begin to run. This doesn't make a vehicle safe from theft however it can delay the theft by at least 15 to 20 minutes. Unfortunately, after a long period of usage, the VATS module in your car could begin to wear out. Each time a 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 have been broken the signal is lost to the module and the car won't begin. You can solve this problem at home by decoding your VATS key. It's not hard to determine the resistance of a key with the multimeter. You can determine the resistance value by placing one of the leads on the prongs of metal on both sides of your key. This method can also be a good method to test a new key to see if it will work in your car. Be sure to remove the key from the ignition before you begin testing it, as the new key could be displaying an incorrect VATS number and will not work in your vehicle. Smart Key Fobs Key fobs today can do more than simply unlock or start the vehicle. They also function as a security device and a burglar deterrent, with a lot of them featuring advanced features that owners may not even know about. They can remotely lock and unlock your doors, make noises that help you find your car in a parking space, or even let you summon your vehicle by pressing a button on your smartphone. This is a lot more functionality than you get from a traditional keychain remote. Smart key fobs are more expensive to replace due to their extra functionality. They also require to be programmed by a dealer. In fact, some retailers will cost upwards of $100 to replace one smart key fob. This is a significant amount to pay for something that spends a lot of its time snagging around in purses and pockets where it can be easily dropped, damaged or exposed to extreme humidity and temperatures. Certain automakers have devised methods to shield smart key fobs from common electronic attacks, such as relay attacks. They are usually paired with remote start hacks that allows thieves access to your vehicle's settings by the transmission of a fake signal another transmitter close to. One method of protecting the key fob's RFID is to put it in an aluminum case or a dedicated RFID blocking case that prevents the transmission of these signals. However, having to remove the key fob from a case that is protected each time you make use of it is a hassle and a detriment to the efficiency of the technology. Certain policies that are more recent, such as auto club memberships and extended warranties can pay for a replacement fob or reimburse you in the event that it gets lost. You can also avoid paying new-car dealership fees by having your fob copied by a locksmith or hardware retailer that provides key-fob cloning. The decision to buy an additional fob is dependent on the significance of your car's keyless entry and start functions. Always keep a spare key or fob in case you lose yours. Batteries Plus offers a large choice of replacement fobs that will fit on most cars and trucks. In addition, our quick and convenient service costs about 50% less than what you'd pay at the dealership. Traditional Keys Traditional car keys are a single piece of metal that has a series of grooves cut into it to fit into a particular lock. They can unlock your locks and also start the car, provided you don't swap them out to a smart or remote key. The only drawback of using a traditional key is that it needs to be physically put into the ignition in order to start the vehicle. If your traditional car key has been damaged or lost you'll need to visit a Gainesville Locksmith to have a new one created. There are a variety of options to select from based on how long it has been since you had your keys cut. Some keys use mechanical cutting machines to produce copies, while others employ laser-cut keys designed with enhanced security features in mind. Modern keys have advanced features such as encryption and anti-theft mechanisms. Encryption makes it more difficult for thieves to duplicate keys or pick locks. Transponder chips are a different anti-theft device. 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 opt to make use of a traditional key, your locksmith can create the new key using an ordinary cutter machine, which can be purchased from most hardware stores. This is less expensive than an electronic key fob or transponder key, and you'll still be able to use your locks, doors and trunk. You can also replace your standard keys for your car with a laser cut version with a distinctive pattern. These keys were first introduced in the 1990s and are an increasingly popular choice for those who want to secure their automobiles. Typically, laser cut keys contain transponder chips that are specifically programmed to work with the specific vehicle you own. If these chips are not installed in your vehicle, they will not respond to the signals sent by the key.
