Installation Guide
This section provides step-by-step instructions for installing your new mechanical keyless entry door lock. A Phillips screwdriver is the only tool required.

1. Prepare the Lock for Installation
Ensure the lock is in its default "no code set" status. For 2nd generation models, all "fish eyes" (dots) on the back of the exterior panel should face inwards. If not, use a flathead screwdriver to turn them inwards.

2. Set Your Passcode
To set your desired passcode (4-6 digits, no repeats), use a flathead screwdriver to turn the "fish eyes" corresponding to your chosen numbers outwards by 180 degrees. The dot (fish eye) facing towards the number indicates a successful setting for that number.

3. Determine Door Handing and Adjust Handle Orientation
The lock is reversible for both left and right-handed doors. To determine your door's handing, view it from the outside: if hinges are on the right, it's right-handed; if hinges are on the left, it's left-handed.
On the back of the exterior panel, locate the spindle hole with an "ARROW". Use the spindle to rotate this hole 360 degrees freely. If the handle is left open, the "ARROW" should face "L". If the handle is right open, the "ARROW" should face "R". Set the handle orientation of the interior panel to match the exterior panel's handle.
4. Install the Latch
Choose the appropriate latch (60mm or 70mm) for your door's backset (2-3/8" or 2-3/4"). Insert the latch into the door edge and secure it tightly with the two short screws provided.
5. Assemble the Panels
- Insert the spindle with spring through the latch.
- Place the black rubber seal behind the exterior panel.
- Put the exterior panel through the spindle with spring.
- Before tightening the mounting bolts, press button C and test your passcode. Only if the handle turns and engages the latch, then proceed to tighten the mounting bolts.
- Line up the interior panel on the other side. Secure the 2 screws on the interior panel (these engage the mounting bolts).
- Use the hex key to tighten the bolt on the handle of the exterior panel. Do not overtighten initially.
- Once the exterior handle bolt is tightened, the handle should not be changed right or left freely.
- Use the hex key to tighten the bolt on the handle of the interior panel as well.
Operating Instructions
Unlocking with Passcode
To unlock the door, first press the 'C' button to clear any previous entries. Then, enter your 4-6 digit combination code. The code can be pressed in any order. Once the correct code is entered, turn the handle to open the door.
Free Passage Mode
The lock features a free passage mode for seamless entry and exiting during periods when the door does not need to be locked (e.g., during business hours). This mode allows the handle to operate freely without requiring a code.
- Enter your own password first.
- Turn the lever to the downward position and hold it.
- While holding the lever downwards, press and hold the 'Y' button.
- Release the lever before releasing the 'Y' button.
- Once the lever is in its original position, Free Passage Mode is engaged.

Disengaging Free Passage Mode
To return to normal password entry mode:
- Turn the lever to fully downward and hold it.
- Press the 'C' button and release the lever.
- The lock is now in normal password entry mode. You will need to type in your password again to open it.
Unlocking with Keys
The lock can also be opened using the provided brass keys. Insert the key into the cylinder and rotate it 90 degrees clockwise to open the lock. This action will also engage the free passage mode. To return to normal password entry mode, rotate the key counter-clockwise 90 degrees. The key can then be pulled out, and the lock will require a passcode for entry.
Maintenance
The ANNFUZ Mechanical Keyless Entry Door Lock is designed for durability and requires minimal maintenance. Regularly wipe the exterior with a soft, damp cloth to remove dust and grime. Avoid using abrasive cleaners or solvents, as these can damage the finish. Ensure the keypad buttons are free of debris for smooth operation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Passcode not working / Lock not opening with code. | Incorrect passcode entered; "fish eyes" not set correctly; lock in free passage mode. | Ensure 'C' button is pressed before entering code. Verify "fish eyes" are correctly set for your passcode. Disengage free passage mode if active. |
| Handle does not engage latch. | Spindle not correctly inserted; mounting bolts too tight or loose; incorrect handle orientation. | Re-insert spindle ensuring it's properly seated. Loosen mounting bolts slightly, test, then re-tighten. Check and adjust handle orientation (L/R). |
| Keys do not operate the lock. | Incorrect key; cylinder issue. | Ensure you are using the correct key. If issues persist, consult a professional locksmith. |
| Lock feels loose after installation. | Mounting screws not tightened sufficiently. | Carefully tighten all mounting screws. Do not overtighten to avoid stripping. |
