    Electronic Locker Lock with Card and Wristband | Type-C Emergency Power | AA Batteries | For DIN Lockers

    Electronic locker lock – a modern and reliable contactless access solution designed for gyms, saunas, swimming pools, offices, and schools. The lock supports fast RFID wristband and card recognition, has a Type-C emergency power input, and several unlocking modes.

    RFID Locker Lock

    The controller responds to configurable RFID wristbands or cards. The lock recognizes the signal instantly, and if the batteries run down, it allows external power to be connected via a standard Type-C cable (e.g., a smartphone charger or a power bank).

    Mounting hardware Mechanical fixing of the lock to the door Suitable for both wooden and metal (steel) locker doors.

    How does the locker's electronic lock work?

    1. Holding a configured RFID wristband or card up to the panel, the reader instantly recognizes the code.
    2. The motor inside the lock retracts the latch and the door unlocks.
    3. If a low battery voltage is detected, the lock notifies the user with a light indicator.
    4. If the batteries are fully depleted, emergency power can be supplied through the external Type-C port to unlock the lock.

    Unlocking modes and logic

    Mode Activation logic Usage scenario
    A: Single-card mode The lock unlocks when any one assigned wristband or card is presented. Designed for individual users with personal or assigned lockers.
    B: Dual-card mode Requires the simultaneous / sequential presentation of two cards (staff member and guest). Ideal for changing rooms.
    Light indication LED indication signals successful / unsuccessful reads and low battery status. Provides the user with clear visual feedback.
    Emergency power function (Type-C)

    If you forget to replace the 4 × AA batteries in time and the lock fully discharges, there's no need to force the door open. The Type-C port built into the front panel allows power to be connected from a regular smartphone charger or a power bank, instantly unlocking the locker.

    Practical example – gym changing room

    A gym visitor is given an RFID wristband. Approaching their assigned locker, they hold the wristband up to the front panel – the lock unlocks instantly. If the lock's 4xAA batteries run down over time, a staff member connects an external battery (power bank) to the Type-C port on the front panel, and the lock opens safely without any damage to the locker door.

    Installation and start-up sequence

    1. Drill the mounting holes in the wooden or metal door according to the specified panel dimensions.
    2. Attach the front panel on the outside and route the connecting cable into the interior of the locker.
    3. Insert 4 pcs. of AA alkaline batteries into the inner lock housing.
    4. Connect the panel cable to the inner lock housing and secure it with screws.
    5. Perform the initial programming of the RFID cards / wristbands and select the required mode (single-card or dual-card).
    6. Test the lock's operation with the door open, then put the locker into service.
