Operating Instructions
Setting Your Combination Code
Your HUANLANG Key Lock Box comes with a default code or no code set. It is crucial to set your own unique combination code immediately after installation. The lock box supports 4 to 12 non-repeating digits, and the order of entry does not matter.
- Open the Lock Box: Rotate the black knob on the front of the lock box to the open position to access the internal mechanism.
- Access the Reset Switch: On the inside of the lock box, locate the reset switch (often a small lever or screw). Rotate this switch to the code setting position (usually 180 degrees).
- Select Your Code: Using the provided screwdriver, rotate the small screws on the back of the keypad for each digit you wish to include in your code. For example, if you want '1-2-3-4' as your code, rotate the screws corresponding to 1, 2, 3, and 4. Ensure these are set to the 'ON' position.
- Record Your Code: Write down your new combination code and store it in a safe, memorable place. Do not store it inside the lock box.
- Confirm Code Setting: Rotate the reset switch back to its original position to lock in the new code.
- Test the Code: Close the lock box. Enter your newly set combination by pressing the corresponding buttons. Then, rotate the black knob to open the box. If it opens, your code is successfully set. If not, repeat the steps.

This image provides a step-by-step visual guide for setting the lock box's code. It shows rotating the knob to open, accessing the internal mechanism, using a screwdriver to set the code digits, recording the code, and testing the new combination.

Opening the Lock Box
To open the lock box with your set combination:
- Enter the Code: Press the buttons corresponding to your combination code. The order in which you press the buttons does not matter, as long as all correct digits are pressed.
- Rotate the Knob: After entering the code, rotate the black knob on the front of the lock box to the open position.
- Access Contents: The front cover will open, allowing access to the keys or other items stored inside.
- Close and Secure: After retrieving or placing items, close the front cover and rotate the black knob back to the locked position to secure the box.
Maintenance
To ensure the longevity and reliable operation of your HUANLANG Key Lock Box, follow these maintenance guidelines:
- Regular Cleaning: Periodically wipe down the exterior of the lock box with a soft, damp cloth to remove dirt and grime. Avoid abrasive cleaners that could damage the finish.
- Check Mechanism: Occasionally check the combination buttons and the opening mechanism for smooth operation. If any stiffness is noted, a small amount of graphite lubricant (not oil-based) can be applied to the moving parts.
- Inspect for Damage: Regularly inspect the lock box for any signs of physical damage, such as cracks, dents, or loose mounting screws. Address any issues promptly to maintain security.
- Weather Protection: Ensure the protective cover is always properly closed when the lock box is not in use to maximize its weatherproof capabilities.
Troubleshooting
If you encounter issues with your HUANLANG Key Lock Box, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock box will not open after entering code. | Incorrect code entered, or code not fully reset after changing. | Ensure all correct digits are pressed. Remember that the order of digits does not matter, but all selected digits must be pressed. Verify that the code setting switch was fully returned to its original position after setting a new code. |
| Difficulty pressing buttons or turning the knob. | Dirt or debris in the mechanism, or lack of lubrication. | Clean the keypad and knob area. Apply a small amount of graphite lubricant to the moving parts if necessary. |
| Code was forgotten. | The combination code was not recorded or remembered. | Unfortunately, if the code is forgotten and not recorded, there is no master key or override. You may need to try common combinations or contact customer support for further assistance, though recovery without the code is generally not possible for security reasons. |
| Lock box feels loose on the wall. | Mounting screws have loosened over time. | Tighten the mounting screws. If the wall anchors are damaged, replace them with new ones. |
