6.2. Installation Methods

Installation varies slightly based on door material (wooden or iron).

For Wooden Doors:

1. Tear off the double-sided tape on the back of the installed board and lock catch.

5. Fasten the lock catch on the door frame.
6. Check the flexibility of the lock and tighten all screws.

For Iron Doors:

The steps are similar to wooden doors, but instead of screws, you will use rivets.

1. After marking the holes on the door, drill holes using a Φ4 drill bit.
2. Fix rivets at the drilled holes using a rivet gun.

Uninstallation Method:

• For wooden doors: Uninstall screws with a screwdriver.
• For iron doors: Uninstall rivets using an electric hand drill or a file.

6.3. Detailed Installation Steps

1. Prepare Lock Catch Direction:
   • Ensure the shortest part of the lock catch aligns with the direction of the Type-C hole on the main lock.
   • Ensure the close-door-side of the lock catch is aligned with the door frame.

   

2. Assemble Main Lock and Installed Board:
   • After inserting the 4 AA batteries (not included), assemble the main lock and the installed board using the 6 M5 hexagon bolts and washers.
   • Assemble the lock catch and main lock together to determine the final installation position of the lock catch.
   • Tear off the double-sided tape on the back of the lock catch, then move and fix it to the door frame.

   

3. Fixing the Lock Catch:
   • Once the lock catch position is determined, remove the main lock.
   • Use a hand-operated electric drill with a 4.2mm drill bit to drill holes for the lock catch.
   • Use a rivet gun and Φ4 rivets to fasten the lock catch securely.
4. Final Main Lock Assembly:
   • Connect the main lock and the lock catch.
   • Tear off the double-sided tape on the back of the installed board, move it into position, and paste it tightly onto the door.
   • Reconnect the main lock with the installed board, fastening with the 6 M5 screws and washers. The entire installation process is now complete.

Important Notice:

Unless you are adding or replacing a remote controller/adapter, do not press the setting key, as it will delete all previously stored data.

8. Maintenance

• Battery Replacement: Replace the 4 AA batteries in the main lock when the low power reminder activates. For remote controllers, replace the CR2032 (3V) lithium battery when its power is low.
• Cleaning: Use a soft, dry cloth to clean the lock body. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
• Regular Checks: Periodically check the lock's mounting screws and the lock catch for tightness and proper alignment.
• Software Updates: For Tuya App-enabled locks, ensure your app and adapter firmware are up to date for optimal performance and security.

9. Troubleshooting

10. User Tips

• Battery Life: To maximize battery life, consider using high-quality alkaline batteries. If the lock is used frequently (e.g., 10 times a day), expect to replace batteries annually.
• Remote Control Range: While the stated range is 20m without obstacles, actual performance may vary depending on environmental factors like walls and interference. Test the range in your specific installation environment.
• App Connectivity: For Tuya App users, a WiFi adapter offers unlimited distance control, which is highly recommended for remote access beyond Bluetooth range.
• Emergency Access: Always be aware of the emergency manual unlocked key's location and how to use it. This is crucial for access during power failures or lock malfunctions.
• Security Best Practices: Even with an invisible lock, ensure your door itself is robust and secure. Regularly check the physical installation for any signs of tampering or loosening.
