2. Setup and Installation
Careful installation is crucial for proper function. Please read all instructions before proceeding.
2.1 Door Compatibility
- Backset: The latch is designed for a 60mm (2-3/8") backset only. A 70mm (2-3/4") latch replacement may be available upon request.
- Door Thickness: Suitable for doors with a thickness of 1-3/8" to 2" (35 mm-50 mm). Not suitable for glass doors.

2.2 Changing Handle Direction
The lock is reversible for both left and right-handed doors. To change the direction of the door handle, use a Phillips screwdriver bit with a shank diameter of 5mm and a shank length of at least 50mm.
2.3 Setting the Combination Code
The password combination can be 4-7 digits, composed of numbers or letters (no repeats), excluding the 'C' button. Always press the 'C' button before entering your code.
To set or change the code, refer to the internal mechanism. The "fish eyes" (pins) on the internal mechanism determine the code. For a pin to be part of the code, its "fish eye" must face outwards (towards 'C'). If it faces inwards (towards 'F'), it is not part of the code. Codes with 4 digits provide maximum security.

3. Operating Instructions
3.1 Unlocking with a Code
To unlock the door, always press the 'C' button first, then enter your 4-7 digit passcode. The digits can be pressed in any order. After entering the code, turn the handle to open the door.
3.2 Auto-Locking Function
The lock features an automatic locking mechanism. Once the door is closed, the lock will engage automatically, securing the door without manual intervention.
3.3 Passage Mode
Passage mode allows the door to remain unlocked, enabling free entry and exit without requiring a code. This is useful for periods of high traffic.
- Activating Passage Mode (Exterior Panel):
- Press 'C' and enter your password.
- Hold the handle with your right hand, press 'Y' with your left hand, then reset the handle. The lock is now in passage mode.

4. Maintenance
The ANNFUZ Mechanical Keyless Entry Door Handle Lock is constructed from solid zinc alloy with a durable plating designed for long-lasting performance. To ensure its longevity and appearance:
- Cleaning: Wipe the lock surface with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: Periodically apply a small amount of graphite lubricant to the internal moving parts of the latch mechanism to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and debris.
- Environmental Exposure: While designed to be sun-resistant and dustproof, extreme weather conditions may require more frequent inspection and cleaning.
- Inspection: Regularly check all screws and components for tightness. Tighten any loose screws to prevent operational issues.
5. Troubleshooting
If you encounter issues with your ANNFUZ lock, refer to the following common troubleshooting steps:
- Lock Not Engaging/Disengaging Smoothly:
- Check for any obstructions in the door frame or strike plate.
- Ensure the latch is properly aligned with the strike plate. Adjust the strike plate if necessary.
- Verify that all mounting screws are tightened correctly, but not overtightened, which can cause binding.
- Apply graphite lubricant to the latch mechanism as described in the Maintenance section.
- Code Not Working:
- Always press the 'C' button before entering the code.
- Ensure you are pressing the correct sequence of buttons. Remember, the order of the code buttons does not matter, only that the correct buttons are pressed.
- Re-check the internal code setting mechanism (refer to Section 2.3) to confirm the pins are set correctly.
- Handle is Loose:
- Tighten the screws that secure the interior and exterior panels to the door.
- Ensure the spindle is correctly inserted and engaging both handles.
- Passage Mode Issues:
- If passage mode does not activate, ensure the switch on the interior panel is fully engaged.
- If passage mode does not deactivate, ensure you are pressing the 'C' button after pressing the handle.
