Car Key Cutting Explained Cutting keys for cars is more than just bending a piece metal. It is a complex procedure that ensures safety, functionality and long-term use of the keys. It is not unusual to lose your car key or even break it in the lock. To ensure that you can always drive your car you'll need a new key cut. Transponder Keys Transponder chips are likely to be fitted in vehicles built in the last 20 years. These microchips are located in the handle of the key and send a signal to the onboard computers in your vehicle when you press the key. The computer onboard is able to verify the serial number digitally of the chip before giving the car permission to start. This prevents thieves from taking over your vehicle, as they would need to be aware of the unique serial number. The microchip inside your car key transmits an unintentional radio signal to the receiver inside the car. The radio signal activates microchip, which then transmits an encoded code to the car's onboard computer. The car will be able to recognize this code and only allow it to start only if the key is the right one. This stops “hot wiring” or other methods to steal cars. Locksmiths that offer these services can create keys for cars with chips. They can also be bought at certain automotive stores like AutoZone. These stores have a large range of keys and can help you find the best one for your vehicle. They can even help you program the chip to your vehicle, which is essential to use it. You can also purchase laser cut keys that are more secure than flat keys. They are more secure than flat keys due to the fact that they have a lock that is harder to pick. They are only duplicated with expensive laser key cutting equipment, or with specialized software. This type of technology is typically found in luxury cars but is now accessible in a wide range of low-cost models. The VATS (vehicle-anti-theft system), key is another type of key that's difficult to duplicate. The keys contain a resistor that's black on the blade of the key. It can be programmed to one of 15 possible values to stop it from starting a vehicle it's not designed to. These keys are costly and require the use of a key programming machine which is only available through certain locksmiths. Keys to VATS Before transponder keys and cars with computers built-in to control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). VATS makes use of a key with a resistor embedded in it to verify that the correct key was used to start the car. The black VATS Pellet in the middle of a VATS Key is not a smart chip like those found on most modern keys. It's just carbon or a block which is sized to have an electrical resistance value. GM employed 15 different resistances for the VATS Pellets and attached them to key blades so that when the key was turned on, the key blades transmit a coded message to module. If the signal matches that of the transistor in a VATS pellet, then the relay in the starter circuit will activate and the engine will start to run. This does not make a car safe from burglary however it could 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. Each time the key is inserted into the ignition it moves two very small wires inside the ignition, and with time, the wires may begin to break. Once enough of the wires are broken then the signal to the module gets lost and the module won't be able to start the car. The good news is that you can solve this problem yourself at home by decoding your VATS key. You'll need a multimeter and a chart to determine the resistance value of your key, but it is not that difficult. You can determine the resistance value by placing one of the leads on the prongs made of metal on both sides of your key. This method is also a good way to test a new key to see whether it will work in your vehicle. Remove the key from the ignition first before you test it. If not, the key may have an incorrect VATS and will not work in your vehicle. Smart Key Fobs Key fobs today are more than simply unlock and start the vehicle. Many of them have advanced features that a lot of owners are not aware of. They can be employed as a security tool or as a deterrent to theft. They can lock and unlock your door from a distance, make chirping noises to assist you in finding your vehicle when you're in a hurry or activate it by pressing the button. This is a lot more functionality than you obtain from a traditional keychain remote. Unfortunately, all that added features also means that smart key fobs could be pricier to replace than standard keychain remotes, and they usually require programming by the dealer. In fact, some retailers will charge up to $100 to replace a single smart key fob. That's a lot to pay for something that is often time snagging around in pockets and purses, where it is easily damaged, dropped, or exposed to extreme humidity and temperatures. Some automakers have developed methods to shield smart key fobs from common electronic attacks, such as relay attacks. These are usually utilized in conjunction with remote-start hacks that allow thieves to gain access to the settings of your vehicle by sending a fake signal from another nearby transmitter. To safeguard a smart fob you can put it in a metal case or put it in an RFID blocking case. This will prevent the transmission of these signals. The convenience of this technology is compromised if you must remove your key fob each time you need to use it from the protective case. Fortunately, some newer car-insurance policies, auto club memberships, and extended warranty coverages will cover the cost of a replacement or reimburse you for the lost fob. You can also avoid paying new-car dealership fees by having your fob copied at a locksmith or hardware store that offers key-fob-cloning services. The decision of whether to purchase a new fob is based on the importance of your car's keyless start and entry functions. It is always advisable to keep a spare key or fob in case you misplace yours. And if you need to purchase a replacement, Batteries Plus has a large selection of fobs to fit most cars and trucks. automotive key cutting near me offer a quick, convenient service that is approximately 50% less than the price you'd pay at the dealership. Traditional Keys The classic car key is a single piece of metal with a series grooves carved into it. These grooves are made to fit specific locks. They can open your locks and begin your car, assuming you haven't replaced them with an electronic key or a remote key. The only downside of using the traditional car key is that you have to physically insert it into the ignition to start the engine. If your traditional car key is lost or broken, you will need to visit an Gainesville Locksmith to get a new one created. Depending on how much time has passed since the last time you cut your keys There are many alternatives to pick from when it comes time to get another copy made. Some keys are cut using mechanical machines or lasers, while others are cut with security features that are enhanced. Some of these modern features that come with modern types of keys include encryption as well as other anti-theft mechanisms. The encryption makes it difficult for thieves to duplicate keys or take locks. Other security features to prevent theft include transponder chips that are incorporated into the key to connect with your vehicle and allow it to only function when it's within the distance of your vehicle. If you choose to use a traditional key, your locksmith can make the new key using a standard 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 doors, locks and trunk.

If these chips are not installed in your vehicle, it will not respond to the signals sent by the key.
