Car Key Cutting Explained Car key cutting is more than simply shaping a piece of metal. It is a complicated procedure that ensures safety, functionality and durability of keys. It is not unusual to lose your car key or have it break off in the lock. To ensure that you are able to always drive your vehicle you'll need to have a replacement key cut. Transponder Keys If your car was built in the past 20 years, it's likely to have transponder chips. These chips are small microchips located in the key's handle that transmit signals to the car's onboard computer when you are using it. The computer onboard checks the serial number digitally of the chip prior to giving the car permission to begin. This stops thieves from stealing your car because they'd have to be aware of the unique serial number. The microchip in your car keys transmits a low-level radio signal to the receiver inside the car. The radio signal activates your microchip, which transmits a instructions to the onboard computer of the car. The car will only begin only if it recognizes the code. This will stop “hot wiring” or other methods of stealing cars. Locksmiths who provide these services can create keys for cars with chips. Some automotive retailers such as AutoZone offer them. They have a vast selection of keys and can assist you in choosing the appropriate one for your vehicle. They can help you program the chip in your vehicle, which is required to use the device. Laser cut keys are more secure than flat keys. They are more secure than traditional flat keys due to having locks that are harder to pick. They can only be duplicated with expensive laser key cutting equipment, or specialized software. This technology is most common in high-end cars but is now accessible 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. The keys have a resistor that is black on the blade of the key. It can be programmed with one of a variety of values to prevent it from starting a car that's not intended to. These keys are more expensive to buy and require a specific key programming device that can only be found at a few locksmiths. Keys to VATS Before transponder keys and cars that had computer chips that control the ignition, GM used a system known as VATS (Vehicle Anti-Theft System). cheap key cutting www.g28carkeys.co.uk utilizes a standard key with a resistor pellet embedded in it to confirm that the correct key is being used to start the vehicle. The black VATS Pellet 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 that is sized to hold an electrical resistance. GM used 15 different resistances for the VATS Pellets. They connected them to key blades in a way that, when the key was turned on, the key blades transmit a coded message to 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 starts to run. This doesn't make a car secure from burglary however, it can deter thieves for at least fifteen to twenty minutes. Unfortunately, after a long period of usage, the VATS module in your car may start to wear out. Each time the key is inserted into the ignition it reroutes two small wires inside the ignition and over time the wires can begin to break. Once enough wires are broken, the signal to the module is not received and it will not start the car. You can solve this issue at home by decoding your VATS code. It's not difficult to determine the resistance value of a key with the multimeter. All you have to do is put one of the leads of your ohm gauge on the prongs made of metal sticking out on both sides of the key. Then examine the display of your ohm meter to find out the resistance value of your key. This is a great way to test a new key and check whether it works in your vehicle. Be sure to remove the key from the ignition prior to testing it, as the new key could have an incorrect VATS value and may not work in your vehicle. Smart Key Fobs for Keys Key fobs today can do more than simply unlock or start the car. They also function as used as a security device and burglar deterrent, with a lot of them featuring advanced features that the owners might not even be aware of. They can remotely lock and unlock your doors, make sounding sounds to help locate your car in a parking space and even allow you to call your vehicle by pressing the button on your phone. That's a lot more than you could ever think of from a standard keychain remote. Unfortunately, all that extra features also means that smart key fobs may be more expensive to replace than standard keychain remotes, and they usually need to be programmed by the dealer. In fact, some dealers charge up to $100 to replace one smart key fob. It's a high price for a product that is often tossed around 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 shield smart key fobs from common electronic threats, including relay attacks. These are often employed in conjunction with remote-start hacks that allow thieves to gain access to your vehicle's settings by transmitting an untrue signal from a nearby transmitter. To secure a smart card to protect it, you can place it in a metal casing or put it in an RFID blocking case. This will block the transmission of these signals. The convenience of the technology is compromised if you need to take your key fob out every time you want to use it from the case. Fortunately, a few of the latest car insurance policies such as auto club memberships and extended warranty coverage will pay for the cost of a replacement or pay for the loss of a fob. You can also avoid paying dealership fees by having your fob copied by a locksmith or hardware store that offers key-fob-cloning services. For most drivers who want to buy an additional key fob is contingent on the importance of your car's keyless entry and push button starter functions are. Always keep an extra key or fob on hand in the event that you misplace yours. Batteries Plus offers a large choice of replacement fobs that fit most cars and trucks. Additionally, we provide a quick, convenient service that costs roughly 50% less than what you'd spend at the dealership. Traditional Keys Traditional keys for cars are a single length of steel that has grooves cut into it to fit in a specific lock. They can unlock your locks and open the car, provided you haven't exchanged them for a smart key or remote key. The only drawback to using an old-fashioned car key is that you must physically insert it into the ignition to start the engine. If your traditional key has been lost, broken or stolen, you'll need to visit an Gainesville locksmith to get a new one cut from the blank. Based on the amount of time that has passed since you last cut your keys, there are several different options to pick from when it comes to having 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 features that come with the modern types of keys include encryption as well as other security mechanisms. Encryption makes it more difficult for thieves to duplicate keys or take locks. Other security features that prevent theft include transponder chips, which are embedded in the key to communicate with your vehicle and allow it to only work when it's within a certain range of your car. If you decide to use a traditional key, your locksmith can create an entirely new key using a standard cutter machine that can be bought from a variety of hardware stores. This is cheaper than a key fob, or a transponder, and you are still able to operate your trunk locks, trunk locks, and doors. You can also replace your standard keys for your car with a laser cut version with a unique pattern. These keys were first introduced in the 1990s and are an increasingly popular choice for those who want to secure their automobiles. Laser cut keys are typically equipped with transponder chip that is programmed to work only with your vehicle. If these chips aren't present in your vehicle, it will not respond to the signals transmitted by the key.
