What you need to know about keyfobs

As the backbone of electronic access control systems, key fobs have gone through several iterations since their introduction in 1983. Early systems were primarily used for car doors and relied on line-of-sight and infrared light, but we could easily be duplicated. Over time, systems were developed that used interrogation-response authentication via RF and now operate primarily via passive RFID tags that allow data to be exchanged via electromagnetic waves.
Remote keys and key cards are used in a variety of access control systems, providing a simple way for small businesses to manage access to their facilities. They are becoming increasingly popular due to their ease of use and customization options, allowing businesses to control who enters which doors, view access records, and adjust access rights as their workforce changes. Wondering if a keycard/fob access system is right for you? Here’s what you need to know.

How do key fobs work?

Modern key fobs work via RFID, a smart barcode system that uses electromagnetic fields to identify and track data on “tags” that contain stored information. The information is transmitted via radio waves. The bar code system works similar to the bar code you see on the back of a physical product or on the magnetic stripe of a credit card – it requires a card reader to capture the information.
To open a door with a key fob, you simply hold or wave the key fob in front of the reader. Each key fob box contains a microchip with a unique frequency that communicates with the reader and indicates that the door should open. fob is programmable to allow different levels of access for different purposes. For example, a building manager’s fob can be programmed to access all doors in the facility, while a receptionist’s fob can be programmed to allow access to several areas.

Why use key fobs?

Remote keys are widely used because they are easy to use and manage. They eliminate the process of wiggling a metal key in the lock – all you have to do is hold or wave the key fob over the reader. Proximity keys are another great option for easy access. Remote keys provide the same functionality as traditional keys, but offer additional convenience and security. If a fob is lost or you wish to deny someone access, you can easily cancel access to that fob.
In addition, key fobs allow you to control who has access to which doors and when, so that you only allow warehouse employees to enter the warehouse during their designated work hours. fob also offers the option to save entry and exit records so that you can track attendance, visitors, or employee movement.

What are proximity keys?

Proximity keys are fobs that allow keyless entry. fobs communicate with a reader via RFID and tell the door that it should be unlocked. Proximity keys are different from key fobs because the key fob must be waved in front of the reader to allow access, while the proximity key can be left in a bag or pocket to unlock the door. Proximity keys are primarily used in cars, but are slowly being used in building access control systems.

Where are they used?

Proximity keys can be used in keyless entry cars, apartment or condo buildings, parking lots, college campuses, gyms, office spaces, restricted area buildings, etc.

Can you make copies of the keys?

Yes but it is a process that requires some technical knowledge and an RFID reader, you can purchase RFID readers online and allow you to read and write 125kHz key fobs, which are the most common type used in apartments and office buildings. If you don’t want to do this yourself, there are several key fob duplication services that can clone the fob for you.
Key fob duplication is not worth worrying about. Doing so is the equivalent of taking your metal keys to a hardware store to have them duplicated. The copy is identical to your original fob and is subject to the same allowances and restrictions.
