This end is typically associated with a particular manufacturer. Manufacturers can stamp blanks with a message such as “Do not duplicate” or an end-user's logo. Locksmiths stock a variety of blanks in order to make the correct keys for customers. Keys are typically made of soft metals, like brass or nickel. The majority of keys are made from one of these alloys. This permits them to be easily ground using a key grinder. The raw material is formed into massive coils, and the material is then pressed through a die or tool into the desired shape. A key blank is completed and plated to guard against corrosion. In the early 1980s, automobile theft was at a record high and General Motors decided to try something new. They launched a Vehicle Anti-Theft System (VATS) key with a transponder embedded in the key's head that was connected to the car's immobiliser. The VATS key worked by sending a message to the computer on board the vehicle. The computer would match the signal with a stored code and if the signal was not compatible with the immobiliser then it could not start up the engine. A locksmith professional could create the VATS key that was compatible with a variety of automobiles at the time. This method of preventing auto theft was not foolproof. Thieves were still able utilize modified key blanks to start the engines of certain vehicles. In 1996, the company improved their security measures, and introduced the next generation of VATS key. The new keys came with an embedded transponder in the head of key blanks, and were programmable using the key programmer. The most commonly used type of key blank is the cylinder blank, which was developed around 150 years ago to offer significantly more security than other locks of the time. Today, cylinder keys are utilized in almost every lock made, including high-quality padlocks, office supply locks, as well as automotive locks. The cylinder blank needs to have a distinct cross sectional profile and match the keyway on a specific lock cylinder. Key fobs Key fobs are a handy way 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 fit in your pocket and can be easily recharged with an easy battery change. Fobs are also more secure than traditional keys because they utilize transponder systems that transmit a unique code to the vehicle's receiver. Depending on your car's model and make it is possible that you will require specific hardware or an expert to reprogram your new key fob. However, it's possible to do it yourself using the proper tools. These tools will save you time and money, and ensure that your new device is programmed correctly. Go through your car's owner's manual for the instructions. If you are unable to locate instructions, call your dealer or checking the internet for details on how to reprogramme the key fob. There are a variety of keyfob programmers on the market. Certain key fob programmers are designed for basic programming, while others are capable of more intricate operations. It is vital to choose the right tool that is compatible with your car's specific model and make. Fobs are becoming more common in cars, as they offer a safer alternative to traditional keys. They are also simpler to use and are more convenient for those with disabilities. It's important to have a spare car key in case you lose your fob. Fobs can be used to provide access control in a variety of commercial and industrial settings, since they can keep track of employee arrivals and departures. This is a great way to monitor employee attendance and monitor break times that are not authorized and determine whether an employee has spent too long away. Fobs can also be programmed to provide different levels of facility access. For instance, a building manager may be granted access to the entire facility, while a worker at the help desk could only be allowed into certain rooms. Chips The technology of cars has evolved dramatically over the past few years. The days of simple mechanical key that could be made at your local hardware shop are long gone. Transponder keys are in use in most vehicles today. They are a combination of a physical key with an electronic key. These keys contain a microchip that responds to radio signals. The computer in the vehicle reads the signal and determines if it is the right key. If not, it will be unable to start. This is a great anti-theft device. However, car key programming requires a spare key to program the chip. A lot of auto dealerships or locksmiths provide the ability to cut and program the new key for you, but not all of them are able to do this. Some manufacturers use proprietary technology to ensure that only the dealer is able to create a key. If your car is a model that is newer that is not yet in production, it could require the use of a specific key programming tool. These tools are bidirectional and can be connected to OBD-II ports. They can read data from the module, EEPROM chip or a new key. This is crucial since the information on keys can be lost if the module is replaced or reflashed. A majority of these tools are able to be used with ease. They will read the VIN of your vehicle and then send this information to a specific transmitter in the key. The transponder responds to the code and the car will recognize the key. One disadvantage of this system is that it could be difficult to duplicate keys, which is why it is recommended to always have an extra. It is also possible that a mis programmed key can harm the vehicle, which is why it's best to have an expert handle this task. Programming a new key may be a complicated process, but it is relatively secure if you follow the directions carefully. It may take a few moments to program a new key, depending on whether your vehicle has an onboard procedure. The process may take a few hours or even a full day for more complex cars. A specific tool that is connected to the OBD-II connector is required.
