how do key fobs work

Key fobs are small electronic devices that have the ability to open certain doors, such as a car door or a door to a building. Except for the fact that they operate in a remote fashion, their function is generally the same as that of a traditional metal key. Each key fob is programmed to match a particular door or set of doors, which provides an additional level of security. Most key fobs are small enough to be carried in a pocket or on a key ring.

How Key Fobs Work

Key fobs use radio waves to communicate with a reader in the door latch that they are programmed to open. They use a system known as radio frequency identification (RFID), which operates like an electronic barcode for identification purposes. In some respects, it serves the same purpose as a barcode on a credit card. However, its placement does not have to be as precise. When the key fob is in close proximity to the reader, the locking mechanism within the door opens and grants access to the person who has the fob.

Key Fob System for Apartments

Key fobs are ideal for apartment complexes and gated communities. A key fob system for apartments can be designed to grant access to common areas, such as the main gate, community pool and storage facilities. Fobs can also be programmed to open the door to individual residences. This makes it easy for a tenant to grant access to cleaning crews, dog walkers and babysitters without having to worry about a key being copied. Fobs are also good for vacation rentals.

Key Fob System for Business

Key fobs also work well in a business environment. One reason for this is because of the additional security they provide. Fobs can be immediately blocked if they have been lost or stolen. They can also be blocked when an employee is let go or a service contract is terminated. Some businesses regularly change the access code for restricted areas and reprogram the fobs accordingly. Additionally, it is possible to integrate fobs into a commercial security system. Among other benefits, this provides a way to track all employee and visitor movements.

How to Program a Key Fob

Although key fobs have many advantages over traditional keys, one disadvantage is that they may be difficult to program. First of all, you will need to purchase an RFID writer and at least one blank fob. You can copy an existing fob by reading its information with the RFID device. Then you can use that same device to write the information to a new fob.
