Car Key Cutting Explained Cutting keys for cars is more than just bending metal. It is a complex process that guarantees security, function and durability of keys. It is not unusual to lose your car key or even have it break in the lock. You'll require a new car key in order to ensure that you are able to drive your car at all times. Transponder Keys Transponder chips are likely to be added to cars that were built in the last 20 years. These chips are small microchips inside the handle of your key which transmit signals to the car's onboard computer when you are using it. The computer in the car checks the serial number digitally of the chip before allowing the car to begin. This stops thieves from hijacking your vehicle because they'd have to be aware of the unique serial number. The microchip inside the key transmits a low-level signal the receiver within the car. This radio signal activates the microchip, and it then sends a code to the car's onboard computer. The car will recognize the code and only allow it to start only if it is the correct one. This stops “hot wiring” or other methods to steal cars. Car keys with chips can be made at a locksmith that offers these services. They can also be bought at a few automotive stores, such as AutoZone. These stores have a large selection of keys, and can assist you in choosing the right one for your car. They can assist you in programming your car's chip which is needed to use the device. You can also purchase laser cut keys that are more secure than traditional flat keys. They are more secure than traditional flat keys due to having locks that are harder to pick. They can only be duplicated using expensive laser key cutting machines, or with specialized software. This technology is most common in luxury cars but is now accessible on many affordable models. The VATS (vehicle-anti-theft system) key is a different kind of key that is difficult to duplicate. These keys contain a resistor that's black on the blade of the key. It can be programmed with one of a variety of values to stop it from starting a car that's not designed to. These keys are more expensive to purchase and require a specific key programming machine that is only located at certain locksmiths. VATS Keys Before the advent of transponder keys as well as cars equipped with computer chips that control the ignition of the car, GM used something called VATS (Vehicle Anti-Theft System). VATS uses an ordinary key that has a resistor pellet embedded within it to verify that the correct key is being used to start the vehicle. The VATS pellet that is black located in the middle of a VATS Key is not a smart chip as used on the majority of modern keys. It is simply carbon or a block which is sized to have an electrical resistance. GM used 15 different resistance values for the VATS pellets and attached the key's blade, so that when the key is turned on in the ignition the coded signal is sent to the module. If the signal is in line with 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 burglar-proof however it could delay the thief for a minimum of 15 to 20 minutes. Unfortunately, after a significant amount of use the VATS module in your car can start to wear out. Each time a key is inserted into the ignition it moves two tiny wires inside the ignition and with time, the wires could start to break. Once enough of the wires are broken then the signal to the module is lost and the module won't be able to start the car. You can solve this problem at home yourself by decoding your VATS key. You'll require a multimeter as well as an indicator chart to determine the resistance value of your key, but it's not difficult at all. All you have to do is place one of the leads of your ohm meter onto the prongs made of metal visible on both sides of the key, and then read the ohm meter's display to find out the resistance of your key. This is also a great way to test the new key to determine whether it works in your vehicle. Remove the ignition key first before you test it. In the event that it is not removed, the key may have an incorrect VATS and not function in your vehicle. Smart Key Fobs for Keys Today's key fobs are more than just a way to unlock or start the car. They also function as a security device and a security measure against theft, with many of them featuring advanced features that owners may not even be aware of. They can remotely lock and unlock your doors, emit noises that help you locate your car in a parking lot and even allow you to call your vehicle by pressing the button on your phone. This is a lot more than you'd expect from the traditional keychain remote. Unfortunately, all that added capabilities also means that smart key fobs may be more expensive to replace than traditional keychain remotes, and they usually require programming by the dealer. In fact, some dealers will charge up to $100 to replace one smart key fob. It's a huge cost to pay for a product that is often tossed around in pockets and purses in the event that it gets damaged, thrown or exposed to extreme temperatures and humidity. Some automakers have developed methods to protect smart keyfobs from common electronic threats, including relay attacks. These are usually used in combination with a remote-start hack that allows thieves to access your vehicle's settings through an untrue signal from a nearby transmitter. One method of protecting a smart key fob is to keep it in an aluminum case or an RFID blocking case that prevents the transmission of these signals. The convenience of this technology is diminished if you have to remove your key fob every time you use it from the case. Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty coverage will cover the cost of a replacement 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 of whether to purchase an additional fob is dependent on the significance of your car's keyless entry and start functions. In any event it is advisable to keep an extra key or fob handy just in case you lose yours. Batteries Plus offers a large selection of replacement fobs that will fit in most vehicles and trucks. We also offer an easy, fast service that costs roughly 50% less than the price you'd buy from a dealership. car key cutting cost are a single piece of metal with grooves cut into it to fit in a specific lock. These keys will open your locks and start your car, provided you don't replace them with a remote key or smart key. The only drawback to using the traditional key is that it has to be physically placed into the ignition in order to start the vehicle. If your traditional car key is lost or broken you'll need to visit the Gainesville locksmith to get a new one created. Depending on how long has passed since you last cut your keys, there are several different options to pick from when it comes time to get another copy. Certain keys are cut with mechanical machines and others are laser-cut with added security features. Some of these advanced features that are included in modern-day keys include encryption as well as other anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Transponder chips are a different security feature that prevents theft. They are embedded into the key and can communicate with your vehicle. This means that it can only function only when you're within certain distance. If you choose to use a traditional key, your locksmith can make an entirely new key using an ordinary cutter machine, which can be purchased from most hardware stores. This is less expensive than using the key fob or transponder key, and you'll be able to operate your doors, locks and trunk. Another alternative is to have your traditional car key substituted with a laser-cut version that has a unique pattern. The first keys of this kind were released in the early 1990s and are an increasingly popular choice for those who want to protect their vehicles. Typically, laser cut keys have special transponder chips that are designed to work only for your specific vehicle. If the chips aren't present in your car, it won't respond to the signals coming from the key and won't start.
