Key blanks A key blank is a piece metal that is not cut according to a specific bitting. Keys are usually rectangular, with a large flat apex at the bow. This end is typically associated with a particular manufacturer. Manufacturers may stamp blanks with a message such as “Do not duplicate” or an end-user's logo. Locksmiths stock a variety of blanks so they can make the correct keys for their customers. Keys are typically made of soft metals, like brass or nickel. Almost all keys are cast from one or the other of these alloys, which enables them to be easily ground by a key grinder. The raw material is formed into massive coils, and then the metal is pressed through a tool/die to form the desired shape. The key blank is coated and finished to shield it from rust. In the early 1980s, automobile theft was at an all-time high, and General Motors decided to try something new. They introduced the Vehicle Anti-Theft System (VATS) key that had a transponder in the key's head that was linked to the vehicle's immobiliser. The VATS key was an effective protection against auto theft and it functioned by sending an electronic signal to the car's onboard computer. The computer then compared the signal to a stored code, and when the key was not paired to the immobiliser, it might not start the engine. The VATS key was created by a professional locksmith, and it was compatible with all of the automobiles manufactured at the time. However this method of preventing theft of vehicles was not foolproof. thieves were able to use key blanks that were modified to start the engine of certain vehicles. In 1996, the company boosted their security measures and released the next generation of VATS keys. The new keys featured an embedded transponder in the head of the key blanks and could be programmed using an exclusive key programmer. The most common type of key blank is the cylinder blank that was invented more than 150 years ago to provide considerably more security than other locks at that time. Today, cylinder key blanks are used in almost every lock manufactured including top-quality padlocks and office supply locks and automobile locks. The blank for cylinder keys has distinct cross-sectional shape, and it should match the keyway of a specific lock cylinder to be used. Key fobs Key fobs can be a useful method to control electronic locks. They are used to unlock cars but they can be used to control home alarm systems as well as garage openers. They are small enough to be able to fit in your pocket, and they can be recharged using an easy battery change. Fobs are also more secure than traditional keys because they utilize transponder technology that transmits an individual code to the vehicle's receiver. Depending on the brand and model of your car the process of reprogramming your car's fob might require special equipment or an expert. You can do it yourself if you have the right tools. These tools will save you time and money, and ensure your new fob is programmed correctly. Look through the owner's manual of your vehicle for directions. If you're unable to locate instructions for reprogramming your fob, you can call your dealer or search the internet. There are many kinds of key fob programmers on the market. Certain key fob programs are designed to be used for basic programming, whereas others are capable of more intricate operations. However, it is important to choose a tool that is compatible with your specific vehicle's model and make. Fobs are becoming more common in automobiles, since they are a safer alternative to traditional keys. They are also easier to use and can be more convenient for people with disabilities. However, it's important to have a spare car key on hand in case you lose your fob. Fobs can be used for access control in many industrial and commercial settings since they can track employee departures and arrivals. They can also be used to monitor attendance of employees and break times that are not authorized and determine whether an employee has spent too much time away. Fobs can also be programmed for different levels of access to facilities.

Chips Car technology has gone through several changes over the years. There are no more simple mechanical keys that can be purchased at your local hardware store. Transponder keys are found in a majority of automobiles today. They are a combination of a physical key with an electronic key. The keys are equipped with a microchip that responds to a radio signal. The computer of the vehicle reads this signal and determines if the key is the correct key. If not, it will refuse to start. This system is an excellent protection against theft. However, it also requires you to have a spare key in order to program the chip. Many locksmiths or auto dealerships provide the ability to cut and program keys for you, but not all of them can do this. Certain manufacturers use proprietary technology to ensure that only the dealer can create keys. Your vehicle might require the use of a key programming tool, especially when it is a modern model. These tools are bidirectional and can be connected to the OBD-II ports. They can read information from the module, EEPROM chip or a new key. This is important because the information contained in a key can be lost if the module is replaced or reflashed. Most of these tools are relatively easy to use. They will scan your VIN and transmit the information to a transponder inside the key. The transponder responds to the code, and the car recognizes the key. It isn't easy to duplicate a key with this system, which is why it's ideal to always have an additional. A key that is not properly programmed can also damage the vehicle.
