Electronic keypad cabinet lock – touch keypad, public and private modes, emergency USB Type-C power input
Electronic keypad cabinet lock is designed for locking wardrobes, cabinets, drawers, changing-room storage compartments and other wooden or metal furniture. The door is unlocked by entering the configured password, eliminating the need to carry a mechanical key or worry about losing it.
The touch-sensitive numeric keypad is backlit, making the lock convenient to operate even in poorly lit rooms. A password of 4 to 15 digits can be set, the protective virtual password function can be used, and the public and private operating modes allow the lock to be adapted for both personal use and temporary use by multiple users.
The lock is powered by four AA batteries. A warning is issued when the batteries are running low, and if they are completely discharged, the lock can be temporarily powered through the external USB Type-C emergency power connector to enter a valid code.
Keyless unlocking:
For everyday use, the lock is operated using the touch-sensitive numeric keypad. User and administrator passwords are supported, and the selected code remains stored even after the batteries are replaced or removed.Important information about the USB Type-C connector:
The USB Type-C connector is intended for emergency external powerwhen the lock batteries are depleted. It is not intended to charge the installed AA batteries. After connecting an external power source, the correct user or administrator password must still be entered.Use in public locations:
The suitability of the lock for a particular gym, school, employee changing room or other publicly used area depends on the administration procedure, usage intensity and required level of security. This is a furniture lock and does not replace a certified high-security door or safe locking system.Control

A touch-sensitive numeric keypad is installed on the front of the lock.
When the keypad is activated, the backlight turns on, helping users see the digits in a darker changing room, wardrobe, office or other poorly lit location.
Main control advantages:- No mechanical key is required.
- The password can be set and changed by the user.
- The numeric keypad remains visible in low-light conditions.
- The lock can be used both privately and on publicly used lockers.
4–15-digit password
The user password can contain from 4 to 15 digits. A longer code provides more possible combinations and reduces the likelihood of accidental guessing.
The lock supports a separate user password and administrator password. The user code is intended for normal unlocking, while the administrator code can be used to manage the lock or access the cabinet if the user code has been forgotten.
Administrator code security:
Only the responsible person should know the administrator password. Do not leave the factory code unchanged and do not keep it written down near the cabinet.Virtual password protection against code observation
The virtual password function allows additional random digits to be entered before or after the actual code. The lock recognises the correct secret combination within the longer sequence of entered digits.
For example, if the actual password is 12345, additional digits can be entered before and after it:
8372 12345 9061This function makes it more difficult for another person observing from the side to determine the actual password.
Important:
The virtual password function reduces the risk of the code being observed, but does not provide complete protection. The password should be changed periodically and must not be disclosed to unauthorised persons.Private mode
Private mode is intended for the permanent use of one person, a family member or a specific employee. The configured user password remains valid for a long period and can be used repeatedly to unlock the same cabinet.
This mode is suitable for home cabinets, personal drawers, workplace document cabinets, storage assigned to an employee and other permanently used furniture compartments.
Private mode operation:- The cabinet is assigned to a permanent user.
- The user sets their own password.
- The same code remains valid for repeated use.
- The password remains valid until it is changed.
Public mode
Public mode is intended for cabinets that are not permanently assigned to one person. Each new user can select a temporary password for one usage cycle.
After the cabinet is locked, the code selected by the user remains valid until it is unlocked. Once the lock is opened, the previous temporary code is no longer valid and the next user can set a new code.
Example of public mode operation:- The user selects an available cabinet.
- They place their belongings inside and set a temporary password.
- They later unlock the cabinet using the same code.
- After unlocking, the previous user's code is deleted and the cabinet is prepared for the next user.
Public mode can be used in fitness clubs, yoga studios, schools, offices, changing rooms and other locations where storage lockers are used by changing users.
Mode configuration:
The procedure for switching between public and private modes must be performed in accordance with the programming instructions supplied with the specific lock.Automatic locking
The lock includes an automatic locking system. The locking mechanism is controlled electronically and secures the furniture door or drawer once the configured locking action has been completed.
For reliable operation, the lock body, latch and strike plate must be installed precisely. The furniture door must close freely, remain correctly aligned and must not push the lock mechanism sideways.
Installation accuracy:
An inaccurately aligned locking mechanism may jam, fail to lock completely or consume battery power unnecessarily. The lock must not be used to pull deformed doors into position.Incorrect password alarm
Entering an incorrect password four consecutive times activates an automatic warning signal. This function helps draw attention to a possible attempt to guess the code and temporarily makes repeated unauthorised unlocking attempts more difficult.
Powered by four AA batteries
The lock is powered by four AA batteries. According to the supplied information, one set of batteries may provide up to approximately 10,000 locking and unlocking cycles.
Actual battery life depends on battery type and quality, frequency of use, ambient temperature, mechanical load and use of the keypad backlight.
When the batteries are running low:
The lock provides a low-battery warning. When this signal appears, the batteries should be replaced immediately rather than waiting until they are completely depleted.Battery use:
Use four AA batteries of the same type, capacity and similar charge level. Do not mix new and used batteries. Observe the polarity marked inside the battery compartment.Emergency power through USB Type-C
If the batteries are completely discharged and the touch keypad no longer switches on, a power bank or another suitable USB power source can be connected to the external USB Type-C connector.
Once temporary power is supplied, the keypad is activated and the lock can be opened by entering a valid user or administrator code. After opening the cabinet, the internal AA batteries must be replaced.
Emergency unlocking procedure:- Connect a suitable USB power source to the Type-C connector.
- Wait for the touch keypad to switch on.
- Enter a valid user or administrator code.
- Open the cabinet.
- Replace the four AA batteries.
Password retention during power loss
The configured passwords remain stored in the lock memory even when power is interrupted or the batteries are replaced. After installing new batteries, the user password does not need to be programmed again each time.
This simplifies lock maintenance and reduces the risk of losing existing access settings after replacing the batteries.
Separate front panel and lock mechanism
The lock has a split design: the touch-sensitive control panel is installed on the outside of the furniture, while the lock body and locking mechanism are installed on the inside.
This design allows the control panel to be integrated compactly into the furniture door, while the internal mechanism can be adapted to the cabinet, drawer or door construction.
Suitable for wooden and metal furniture
The lock can be installed on wooden and metal cabinet doors, drawer fronts and other furniture with a suitable construction. The specified suitable mounting surface thickness is 0.6 to 20 mm.
Thin sheet metal may require additional reinforcement to prevent the lock from deforming or moving. In wooden doors, the openings must be prepared accurately and the fasteners must not be overtightened.
Before installation:
Check the door thickness, opening direction, internal space for the lock body, direction of latch movement and strike mounting location. The drilled openings must correspond to the installation drawing for the specific product.Durable zinc alloy housing
The front panel and main structural components of the lock are made of zinc alloy. The metal housing is more resistant to everyday mechanical impact than a simple plastic construction.
