3. Installation Guide
The BIWIBON Smart Door Knob is designed for easy installation, typically replacing existing door knobs. Follow these steps carefully.
3.1 Prepare Your Door
- Ensure your door thickness is between 1-3/8" (35mm) and 2-1/8" (55mm).
- Verify the backset (distance from door edge to center of bore hole) is either 2-3/8" (60mm) or 2-3/4" (70mm).
- Confirm the bore hole diameter is 2-1/8" (54mm).
- The door edge should be chiseled for the latch plate to sit flush. If not, chisel it according to the provided template.
This image illustrates the required door dimensions (thickness, backset, bore hole diameter) and emphasizes the need for the door edge to be chiseled for proper latch plate installation. It shows both "Not Chiseled" (incorrect) and "Chiseled" (correct) examples.
3.2 Install the Latch
- Insert the adjustable latch into the door edge, ensuring the bevel of the latch bolt faces the door frame.
- Secure the latch with the provided screws.
3.3 Install the Exterior and Interior Knobs
- Connect the spindle to the exterior knob.
- Pass the spindle and the wire from the exterior knob through the latch mechanism and the bore hole.
- Align the interior knob with the spindle and the threaded pillars. Ensure the wire from the exterior knob is connected to the interior knob's port. The connector has a black side that should face up for proper connection.
- Secure the interior knob to the exterior knob using the threaded pillars and screws.

4.3 Operational Modes
- Privacy Mode: Activates a manual deadbolt-like function, preventing unlocking even with programmed credentials. Ideal for ensuring complete privacy. To activate, slide the privacy switch on the interior knob. Warning: Do not activate privacy mode while the door is open or the room is unoccupied, as this will restrict access.
- Passage Mode: Keeps the door unlocked for continuous access without needing credentials. Useful for high-traffic areas or during gatherings.
- Silent Mode: Disables all sound notifications from the lock, allowing for quiet entry and exit.
- Auto-Lock: Automatically locks the door after a set period (e.g., 5 seconds) of inactivity. This feature ensures the door is always secured.
This image illustrates the "Real Privacy Mode" feature, showing how a switch on the interior knob can be engaged to prevent anyone from entering without permission. A warning is included about not activating this mode when the door is open or the room is unoccupied.
4.4 Remote and Voice Control (Optional)

- Connect the BIWIBON Gateway to your home Wi-Fi network.
- Pair the smart door knob with the gateway through the Tuya Smart app.

- Emergency Power: If batteries die completely, use the Type-C port on the exterior knob with a power bank for temporary emergency power to unlock the door. This port is for power only, not for charging the internal batteries.
- Cleaning: Wipe the lock surface with a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish or electronic components.
- Key Storage: Keep at least one spare physical key in a secure, easily accessible location outside the locked area for emergencies.
