4. Installation Guide
Before installation, ensure the surface is clean and dry. The lock can be installed using screws or adhesive pads. For optimal security and longevity, screw installation is recommended.
Important Note on Thickness: The white RFID key cards can penetrate wooden surfaces up to 4.5 cm (1.77 inches) thick. The blue key fobs can penetrate wooden surfaces up to 2.54 cm (1 inch) thick. If the material thickness exceeds these limits, the RFID signal may not be detected, preventing the lock from opening.
