BIO-S80A is the most frequently purchased electronic hidden cabinet lock.
The invisible cabinet lock BIO-S80A (80x80x27mm) is a larger model compared to the BIO-S61A (61x61x21mm) and is available in two colors – black or white. The RFID combination lock BIO-S80A can be optionally unlocked using a smartphone (if the user is within Bluetooth range) or traditionally by placing an RFID proximity card or an RFID fob/tag. An app for operating the invisible cabinet lock is available for Android and iPhones.

Hidden lock for cabinet with RFID proximity card

The electronic RFID card cabinet lock is powered by four AAA batteries, allowing it to last significantly longer than the small drawer lock BIO-S61A. If the voltage is low, a sound alarm will be triggered, and the lock will automatically release. Automatic lock release in the furniture lock is a programmable option.

The hidden cabinet lock from the BIO-S80A and BIO-S61A series has an additional functionality to inform the user about an open cabinet or drawer. 60 seconds after opening the cabinet, the lock will emit a continuous ‘di’ sound, and a red LED will light up for about 10 seconds.

All offered electronic furniture locks (invisible or with an additional external panel) can be:
additionally powered by an external DC power supply,
programmed to work in 3 different modes: public mode, restricted public mode, or private mode (description of the work modes under the table).

Each set includes:

  • Electronic RFID lock (body + bolt/latch)

  • Two proximity cards:

  •       1x Manager proximity card
          1x User proximity card
  • Set of screws

  • User manual

Batteries are not included in the set.

When purchasing a larger quantity of invisible electronic furniture locks, we suggest that, depending on your needs and technical conditions, just before installation:

  • register any card for Manager registration to each furniture lock

  • register all or selected User cards and key fobs to each furniture lock

What happens to the hidden furniture lock when the battery is discharged?

It applies to cabinet and drawer locks from the series: BIO-S61A, BIO-S80A, BIO-S8080A, BIO-S90A, and BIO-S123A.
When using/opening the furniture lock, if the voltage level drops below 4.5V (for BIO-S61A below 2.5V), the electronic furniture lock will emit a double 'di di' beep and the blue LED will light up. The furniture lock will still work, meaning the latch can still be closed.
When using/opening the furniture lock, if the voltage level drops below 4.0V (for BIO-S61A below 2.0V), the furniture lock will remain open (the latch cannot be closed).
In the case of complete battery discharge, the electronic furniture lock will remain closed. We invite you to the FAQ section on what to do in such a situation.
For each purchased electronic furniture lock, only new batteries from a reputable manufacturer, such as Industrial by Duracell, should be inserted. For safety purposes, it is recommended to periodically replace the batteries with new ones. This is a very individual matter, but depending on the frequency of use of the furniture lock, for example, once every 3 months. Alternatively, any RFID electronic furniture lock can be powered by an additional USB 6VDC/2A power supply (1m cable with micro USB, USB type C, or DC 3.25/3.5mm connector). On the FAQ page in the Power Supply of Invisible RFID Furniture Locks section, item 2.5 provides information on how to power multiple electronic furniture locks from a single power supply.

Electronic lock BIO-S80A with front panel  回  Additional authorization methods

The BIO-S80A digital cabinet lock features ergonomic operation. When using an RFID tag or card or the additional Bluetooth option via the mobile app, the device’s response time does not exceed 500 ms, while the reliable servomotor immediately releases the locking bolt. The device can also be equipped with an additional front-mounted panel, allowing for other authorization methods.

In our company, we also considered clients for whom the optimal solution is a furniture combination lock that can be opened and closed by entering a 4 to 8-digit PIN code. Additionally, the RFID cabinet lock can be operated using biometrics through the aforementioned external panel. In this variant, a registered fingerprint is enough to release or activate the lock. The additional authorization methods mean that the cabinet card lock can be opened without using a mobile app, tag, fob, or proximity card. Very high aesthetics of the front panels and the highest quality make them perfectly fit into contemporary interiors.

The electronic RFID card lock from the BIO-S80A series, like every electronic cabinet lock available in our offer, operates in 3 modes, increasing the number of possible applications for the device.

Private mode allows for the creation of a permanent locker for one or several users – for example, household members or office employees authorized for access. The electronic RFID fob cabinet lock in public mode allows the user to temporarily store selected items in the cabinet. Restricted public mode is an intermediate solution, as the locker can be used multiple times until it is assigned to another user.

Operation modes for electronic furniture & cabinets locks:


( 1 ) Open the cabinet and place your items inside.
( 2 ) Close the cabinet and register an RFID card/key fob or enter a PIN code (4-8 digits) to lock the cabinet.
( 3 ) Upon return, present the RFID card/key fob or enter the PIN code to unlock the cabinet, retrieve your items, and close the cabinet.
( 4 ) The cabinet is now open and available for the next user.
