When it comes to key fobs, these are generally used with all sorts of different access control systems in a wide variety of businesses, and they also provide a much simpler method for these same businesses to help with managing entry. Because of both their overall ease of use and available customization options, key fobs have become extremely popular as of late, as businesses both large and small are able to not only control who accesses which doors in the buildings themselves, but also obtain records of entries and exits and make additional further adjustments.

Here are four important things that businesses both large and small should know when it comes to key fobs.

*First and foremost, it’s important to make note of how key fobs actually work. Modern fobs typically work through RFID, which is defined as an intelligent barcode system that utilizes electromagnetic fields that help to identify and track data on specific tags that contain stored information. Radio waves are then used to pass this information. In order to actually open a door using a fob, all you need to do is simply wave or hold the fob in front of the reader, which allows the microchip in the fob to communicate with it. This will indicate that the door needs to be opened. Additionally, fobs are also able to be programmed to allow different levels of access for different users.

*In terms of cost, this typically depends on at least a couple of different factors: the system used by the business and the features that are required. When these are taken into account, an access control system that uses fobs and readers can cost upwards of approximately $1,500 to $2,500 per door with access for up to 150 individuals.

*Similar to traditional keys, it is entirely possible for key fobs to be copied; however, it should be noted that this is a process that not only requires an RFID reader to complete, but also an increased amount of technical knowledge as well. This specific process, however, is one that should never cause concern, as the copy of a key fob is identical to the original one. In other words, if someone was looking to copy a fob hoping to obtain access to portions of a building that they would not have otherwise had access to before, they would not have any luck at all.

*When it comes to the subject of having to possibly reprogram a key fob once the battery, this is something that typically does not need to be done. In the event that you were to have a professional replace the battery, this is something that they should easily be able to do without having to also reprogram the fob itself.
