5. Maintenance

To ensure the longevity and smooth operation of your JESSTTI door handle lock, follow these maintenance guidelines:

• Cleaning: Wipe the handle and plates 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 or a silicone-based spray to the latch mechanism and key cylinder to maintain smooth operation. Do not use oil-based lubricants as they can attract dust and debris.
• Tightening Screws: Over time, screws may loosen. Periodically check and tighten all mounting screws to ensure the handle remains securely attached to the door. Do not overtighten.

6. Troubleshooting

If you encounter issues with your door handle lock, refer to the following common troubleshooting steps:

• Handle is loose: Check and tighten all mounting screws on both the interior and exterior handle assemblies.
• Latch does not retract or extend smoothly:
  • Ensure the latch mechanism is properly aligned within the door edge.
  • Apply lubricant to the latch bolt and internal mechanism.
  • Verify that the spindle is correctly inserted and not bent or obstructed.
• Key is difficult to turn or does not unlock:
  • Ensure the key is fully inserted into the cylinder.
  • Apply graphite lubricant to the key cylinder.
  • Check if the door is binding in the frame, preventing the latch from moving freely.
• Door does not close or latch properly:
  • Inspect the strike plate on the door frame. It may need adjustment to align correctly with the latch bolt.
  • Check for any obstructions in the door frame or around the latch.

If these steps do not resolve the issue, please contact customer support.
