Lock Installation Guidelines

1. Professional Installation RecommendedInstallation should be carried out by an experienced carpenter or a qualified lock installer with  ufficient technical knowledge. According to the fixed-distance template provided in the product manual, accurately drill and chisel the mounting holes for the bracket socket, lock plate, and lock body to ensure proper preparation for installation.

 

2. Accuracy Check and Functional Testing
After drilling, carefully check whether all holes are positioned accurately. Follow the installation steps in the product manual strictly. Once installed, test the lock to ensure smooth operation. If the lock mechanism feels stiff, operates abnormally, or cannot be opened, contact the product distributor or the manufacturer's technical support and after-sales service department promptly for assistance.

 

3. Temporary Removal During Door Painting
If installation and inspection confirm that the lock functions properly, remove the lock before painting the door. Allow the paint to dry completely-preferably for more than 2–3 days-before reinstalling the lock. This is recommended to:

  • Prevent paint adhesion to the lock surface, which may affect both appearance and performance. Paint residue can cause internal components to become stiff or jammed.
  • Avoid chemical corrosion, as gases released during incomplete paint curing can corrode the lock's surface treatment, accelerate finish deterioration, reduce visual quality, and shorten the overall service life of the lock.
