Car Key Cutting Explained Cutting a car key is more than just bending metal. It is a sophisticated process that guarantees security, functionality and the longevity of keys. It is not uncommon to lose keys to your car, or even have them break into the lock. You'll need an alternative car key to ensure that you are able to drive your car at all times. Transponder Keys If your car was constructed within the past 20 years, it's likely to have a transponder chip. These chips are tiny microchips in the key's handle that transmit a signal to the vehicle's onboard computer when you use it. The onboard computer reads the digital serial number inside 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 in order to be able to take over it. The microchip in the key transmits a low-level signal to the car's receiver. The radio signal activates microchip, which then transmits an informational code to the car's onboard computer. The car will only start only if it recognizes the code. This stops the use of "hot wiring" and other methods of taking cars. Car keys with chips can be created at an authorized locksmith who offers these services. They can also be purchased at certain automotive stores, such as AutoZone. They have a vast range of keys and will assist you in choosing the appropriate one for your vehicle. They can assist you in programming your vehicle's chip which is needed to use the device. Laser cut keys are more secure than flat keys. These keys have a lock cylinder that is much harder to pick, and they are only duplicated using expensive laser key cutting equipment or specialized software. This technology is more common in high-end vehicles, however it is now being used in a wide range of low-cost cars too. The VATS (vehicle-anti-theft system) key is another type of key that is difficult to duplicate. These keys have a black resistor in the key blade that is programmed with one of fifteen potential values to prevent them from starting a vehicle that it's not meant to. These keys are more expensive to buy and require a special key programming device that can only be located at certain locksmiths. VATS Keys Before the days of transponder keys and cars equipped with computer chips that control the car's ignition, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded inside it to confirm that the correct key is being used to start the car. The black VATS Pellet in the middle of a VATS Key is not a smart chip as found on most modern keys. It is merely a block or carbon that is sized to provide an electrical resistance. GM employed 15 different resistances for the VATS Pellets. They attached them to key blades in a way that, when the key was turned on, a 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 car secure from theft, but it will delay the theft by at least 15 to 20 minutes. Unfortunately, after a significant amount of use, the VATS module in your car may begin to wear out. The two small wires in the ignition are moved each time the key is inserted. Over time, the wires may begin to break. If enough wires are damaged, the signal is lost to the module and the car will not start. You can solve this issue at home yourself by decoding your VATS key. You'll need a multimeter and a chart to find out the resistance value of your key, but it's not that difficult. All you need to do is place one of the leads of your ohm meter onto the prongs made of metal sticking out on both sides of the key, and then examine the display of your ohm meter to find out the resistance value of your key. This is a great opportunity to test a new key and determine whether it will work in your vehicle. Remove the key from the ignition first before you test it. Otherwise local key cutting may have an incorrect VATS and not function in your vehicle. Smart Key Fobs Key fobs of today do more than just unlock or start a car. They can also be an alarm system and a security measure against theft, with many of them having advanced features that owners may not even know about. They can remotely lock and unlock your doors, emit chirping sounds to help you find your vehicle in a parking lot and even allow you to call your vehicle by pressing a button on your smartphone. This is a lot more functionality than you can obtain from a traditional keychain remote. Smart key fobs are more expensive to replace due to their extra functionality. They also require to be programmed at the dealer. Some dealers charge up to $100 for one smart fob. It's a steep price to pay for a device that is often jostled in purses and pockets in the event that it gets damaged, dropped or exposed to extreme temperatures and moisture. Some automakers have developed methods to protect smart key fobs from common electronic threats, including relay attacks. They are typically employed in conjunction with a remote-start hack that allows thieves to gain access to your vehicle's settings by transmitting a fake signal from another nearby transmitter. One method to safeguard the key fob's RFID is to store it in a metal case or use an RFID blocking case that blocks the transmission of these signals. However, the necessity of removing the key fob from its case that is protected each time you need to use it is not a good way to enjoy the benefits of the technology. Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty insurance policies will cover the cost of replacing a fob or reimburse you for the lost fob. You can also avoid paying dealer fees by having your fob copied by a locksmith or hardware store that offers key-fob-cloning services. The decision to buy a new fob is based on the importance of your car's keyless start and entry functions. In any case, you should always have an extra fob or key in case you lose yours. Batteries Plus offers a large range of replacement fobs that fit most cars and trucks. We also offer an efficient, quick service that costs roughly 50% less than the price you'd buy from a dealership. Traditional Keys Traditional car keys are a single length of metal with a series of grooves cut into it to fit a specific lock. These keys will unlock your locks and open the car, assuming you don't swap them out to a smart or remote key. The only downside of using the traditional car key is that you must physically insert it into the ignition to start the engine. If your car key has been damaged or lost you'll need to visit an Gainesville Locksmith to have a new one created. There are a variety of choices to pick from based on how long it's been since you had your keys cut. Certain keys are cut using mechanical machines or lasers, while others are cut with enhanced security features. Some of these modern features that come with the modern-day keys include encryption and other security mechanisms. Encryption makes it harder for thieves to duplicate keys or open locks. Transponder chips are another anti-theft feature. They are embedded in the key and can communicate with your vehicle. This makes it only function when you're within a certain distance. If you choose to use a traditional standard key, a locksmith could create a new one with a standard key cutting machine, which is available at the majority of hardware stores. This is less expensive than an electronic key fob or transponder key, and you'll still be able to operate your locks, doors and trunk. You can also replace your standard car keys with a laser-cut version with a unique pattern. These keys were introduced in the early 1990s and are a popular option for those who wish to protect their automobiles. The majority of laser cut keys have special transponder chips that are programmed to work only for your specific vehicle. If these chips aren't installed in your car, it won't respond to the signals emanating from the key and won't be able to start.
