Electronic RFID Lock Flexo.RFID for Wood and Steel Furniture


The Flexo.RFID (Radio Frequency Identification) sets a new standard. It has been developed for the leading RFID standards (MIFARE® Classic 1K and MIFARE® DESFire EV). With its three authorization levels (Master, Manager, and User), the locking system offers high flexibility in operation. Like all locks in the Flexo series, the RFID variant allows both recessed installation (Flush-Fit) and retrofitting (Retro-Fit). This allows an existing system to be conveniently and quickly upgraded or transformed into a modern stylish design with Flush-Fit. The innovative design lock - Made in Germany - enables the secure storage of personal items in offices, schools, and sports facilities.

Installation and Operation


The lock can be directly installed in our standardized mounting hole (Retro-Fit) 16x19mm. Alternatively, a 45x47mm mounting hole can be chosen, allowing the lock to be recessed and visually enhanced (Flush-Fit).

Installation Video Flush-Fit

More information can be found in the manual in the download section below this product description. The lock is secured with an M19 nut and can optionally be supplemented with anti-rotation protection (see suitable accessories). By presenting a transponder card or transponder chip, the lock is released. It is then opened or closed by a 90° turning motion. In doing so, the bolt mounted on the back moves to a locking angle, preventing the door from opening. If a user card is lost, the lock can be opened at any time with the Master or Manager card.

Product Features

  • External battery access and battery replacement without dismantling the locking system
  • RFID Standard: MIFARE® Classic 1K/ MIFARE® DESFire EV
  • Integrated occupancy detection with MIFARE® Classic 1K
  • Easy retrofitting, e.g., to replace mechanical locker locks
  • Adjustable bolt (in 90° increments)
  • Minimal front build-up of only 15 mm (in Flush-Fit)
  • Up to 10 user cards can be programmed in private mode
  • Long battery life (25,000 locking cycles / approx. 3 years)
  • Compatibility with all BURG Type B bolts

Important to Note!


To use all functions of the lock, at least 3 cards are required, and the mode change can only be set via the separately available mode change card. For sample orders, we recommend ordering the starter set. The necessary batteries are not included as standard! We recommend using original VARTA 1/2 AA batteries, as this ensures proper operation from our side! You can order the batteries directly from our shop.

  • 1x Locking system
  • 1x Transponder card
  • 1x Bolt fixing screw M6 x 12 mm
  • 1x Mounting insert (only in Flush-Fit)

What Batteries Should Be Used?

Using high-quality brand batteries is absolutely essential for the flawless functioning of the lock. The locking systems are factory-approved for the specified industrial batteries of the VARTA brand. The use of other batteries may result in a reduced number of possible locking cycles. In addition, limited functionality and/or functional problems are likely. Experience shows that other batteries, even with the same specifications, have different performance characteristics. Therefore, BURG does not guarantee the (functionality) of the lock when using batteries other than those mentioned above.
