Who it fits
Good fit for
This lock suits families, Airbnb hosts, and office managers who need to manage many users. The 100-fingerprint and 100-passcode capacity handles staff and guests well. You can create one-time or timed codes for deliveries or housekeepers. The local data storage appeals to privacy-conscious users. It also fits left- and right-handed doors, making it a flexible choice for DIY installation on standard US doors.
Who should skip it
You should look elsewhere if you need video monitoring or two-way audio. This model is a door knob, not a full smart lock system with a camera. It lacks Wi-Fi connectivity for remote control without the app. If you require integration with other smart home ecosystems beyond the dedicated app, this unit may not fit your setup. It also does not include a keypad on the exterior, relying on app or fingerprint for entry.
Verdict: The BIWIBON 5-in-1 Smart Door Knob is a solid choice for managing multiple users with high capacity and local privacy. It works best for standard doors where keyless flexibility is the main priority.

Size: 2.75 inches width, 2.75 inches height, 5.7 inches length
These dimensions describe the physical footprint of the door knob. You must measure your existing door hardware to ensure a proper fit.

Physical Design and Build Details

The listing shows it in Silver 02 or Black 03. These finishes are standard for interior hardware, allowing the knob to blend with existing door frames or stand out as a modern accent. The unit includes the knob itself, so you do not need to source separate handles. It is designed for standard US doors with backsets of 2-3/8 inches or 2-1/8 inches. The door thickness must fall between 1-1/8 inches and 2-1/8 inches. This fits most residential entryways and bedroom doors. The design supports both left- and right-handed installations, which simplifies the swap for existing homes. You can adjust the layout to match your door’s swing direction without buying new parts. The compact footprint ensures it does not protrude excessively from the door surface. This keeps hallways clear and reduces the chance of snagging coats or bags. The physical controls are integrated into the knob body, keeping the exterior clean. There are no external buttons or screens visible on the outside face. This minimalist approach maintains a sleek appearance while hiding the electronics inside. The build prioritizes durability through standard hardware dimensions. You get a reliable fit for most standard doors. The weight and size balance ease of use with security needs. It feels sturdy enough for daily family traffic. The design avoids unnecessary bulk, making it suitable for apartments or smaller homes where space is limited. The finish options allow you to match your current decor without clashing. This practical design supports both aesthetics and function.
Setup and everyday use details
Installation fits most US standard doors with a backset of 2-3/8 inches or 2-1/8 inches. The thickness range spans from 1-1/8 to 2-1/8 inches. It works with both left- and right-handed door configurations. You do not need complex tools to mount the knob, as it includes the necessary hardware for a straightforward DIY process. The unit weighs 2.15 pounds, which helps it stay securely in place during daily operation.
Daily use centers on five distinct access methods. You can unlock the door using a fingerprint, a passcode, the mobile app, an IC card, or a mechanical key. The system stores up to 100 fingerprints and 100 passcodes locally. This local storage means your data never uploads to the cloud, keeping your access information private on the device itself. You can also manage up to 100 IC cards for additional users.
Managing access is handled through the app or the lock interface. You can create one-time, timed, or dynamic codes for guests, housekeepers, or delivery personnel. The anti-peep PIN feature allows you to enter random digits before or after your real code to protect your privacy from onlookers. You can customize the auto-lock timing to suit your routine. The app lets you enable silent mode or passage mode, giving you control over how the lock behaves. You can also view access logs to track who enters and exits. This setup suits families, short-term rentals, and offices where multiple people need reliable, keyless entry.
Check Door Specs Before Buying
Before you install this BIWIBON 5-in-1 Fingerprint Smart Door Knob, verify your door’s backset and thickness. It fits standard US doors with a 2-3/8 inch or 2-1/8 inch backset. The thickness must range from 1-1/8 to 2-1/8 inches. Check if your door is left- or right-handed, as the unit accommodates both. You should also consider your access needs. With capacity for 100 fingerprints and 100 passcodes, it suits families or rentals. However, data stays local. If you want remote cloud access, this may not fit. Pair it with a video doorbell for full security. You get keyless entry without app dependency for basic use. Keep mechanical keys handy as backups. Regular maintenance includes cleaning the sensor and checking battery levels. This lock works well alongside other smart locks for comprehensive home security.
