The Fafeicy Smart Lock is designed for versatile installation on various door types. Ensure your door meets the specified thickness and crevice space requirements.
- Prepare the Door: For 8mm glass doors, an additional thick plate is required for proper fitting. For framed double opening glass doors, drilling holes may be necessary, and the metal frame might need to be hollow if its width is more than 50mm.
- Position the Lock: Place the main lock body and sub lock body on the door, ensuring correct alignment for your door type (single opening, double opening, frameless, or framed).
- Secure the Lock: Use the provided installation slabs and screws to firmly attach both lock bodies to the door. Ensure the double hook locking latch engages correctly.
- Test Mechanism: After installation, manually check the locking and unlocking mechanism to ensure smooth operation.
