What are Key Fobs

A key fob is a small item that is attached to your key with a chain and key ring. Key fobs are usually attached to keys to make it easier for you to find them and to give you a better grip on your keys. They are also called key chains or key rings. There are a lot of different types of key fobs. In this article we will find out more about the different types of key fobs.
Key fobs can be simple and of purely aesthetic value. They may be a simple disc made out of metal or plastic. These discs usually have some sort of logo on them as they are supposed to show some sort of affiliation or be symbol or something. Nowadays a lot of key fobs are actually tools. These days it is not uncommon to find a small flash light, knife or bottle opener as a fey fob. As technology has advanced key fobs have become more and more advanced. You can find small calculators to use as a key fob or a remote control or even a pen drive.
Key fobs are also being used for access control. You can now open your car with the touch of a button on your key fob. Unlike early key fobs you no longer need a line of sight and the newer key fobs are a lot more difficult to duplicate. Key fobs are also being used in apartment buildings. They are a great way to restrict access to public areas like the pool to certain times of the day. Electronic key fobs have become very common and are very useful and they do not require a lot of maintenance except for the fact that you may need to change the key fob battery after a while. Changing the key fob battery is not very hard and if you do not want to do it yourself you can easily find someone to do it for you.
