Key Fob Security: Get to Know Your Key Fob and How to Protect It (and Your Property) Key fobs are small yet powerful electronic remote keys that allow entry into electronically restricted facilities and devices securely. Learn more about how they work and keep them protected against risks here. What Is a Key Fob? A key fob is a small physical device that provides access to a house, building, or car. The key fob is programmable to allow someone entry to authorized areas like buildings. The device in this setup acts as a person’s identification whose access can be activated or deactivated. Key fobs allow hands-free, keyless entry. The handy device replaces traditional keys to access a matching car or office door, as programmed. For building managers, office managers, and business owners, implementing a keyless system with fobs is a practical solution for managing and controlling people’s entry into and exit out of their premises. Car owners use fobs to quickly and conveniently lock and unlock their vehicles without keys and from a distance. They also use the key fobs to start the engine, open the trunk, set off the car alarm, and activate other functions. How Does a Key Fob Work? A key fob uses RFID or radio frequency identification technology. RFID refers to a wireless, contactless communication system that uses radio frequencies to track and identify objects with tags attached to them. It mainly requires two things for an RFID system to work: The key fob contains a microchip where information like a unique ID is stored and an antenna for receiving and transmitting data. These components comprise the RFID tag, or transponder, that communicates with an RFID reader. The RFID reader uses radio waves to scan the tag and read its stored information. The scanning device has to be in the same range as the fob to detect it. How to Classify RFID Systems By Frequency RFID tags operate on low, high, or ultra-high frequencies, as governing authorities allow for RFID key fob syst
