RAFECIEE G99 plus Smart Biometric Door Knob with App, Keypad and Auto-Lock

Quick overview

Made from aluminum with a matte black, powder-coated finish, the RAFECIEE G99 plus measures 8.74 inches long by 3.7 inches wide. It offers fingerprint, passcode, Bluetooth app, and mechanical key access. Use it on a bedroom, office, or apartment door when several people need convenient ways to enter. Compared with a traditional key-only knob, it adds options for managing access without changing the basic door-knob format.

Fingerprint access, personalized passcodes, and a backup key give household members or coworkers different ways to unlock the door. The lock can store up to 50 fingerprints, and the keypad includes an anti-peeping password feature. In the app, you can manage users, share permanent or temporary access codes, and view access history, app control works within Bluetooth range. Fingerprint data is stored locally rather than uploaded to the cloud. Auto-lock is set for five seconds, while passage, private, and mute modes let you adapt entry to the room and routine.

How to use it

The knob is designed for US standard doors from 1-3/8 to 2 inches thick. Installation uses a screwdriver, and the UP marks on the inner and outer handles should align during setup. Check that the door dimensions suit the lock before installation so the hardware fits the intended door.

The lock uses four AAA alkaline batteries, which are recommended for up to six months of use, batteries are not pre-installed. Low-battery alerts help you know when to replace them. If the batteries run out, the mechanical key provides an unlocking option, and the Type-C port can be used for emergency power and unlocking. It is not a charging port for rechargeable batteries. For fingerprint setup, use a clean, dry finger and register it from multiple angles to support reliable recognition.

Tips for day-to-day use

Set up the fingerprints and passcodes for the people who use the door, then use app controls to share temporary access with visitors or service providers when needed. Because app access relies on Bluetooth, use the keypad, fingerprint reader, or key when you are outside its Bluetooth range. Access history can help you review entry activity, while mute mode is useful when you want quieter operation. Passage mode allows free entry and exit, and private mode offers another way to tailor access to the room.

Buyer feedback highlights straightforward installation and useful functionality. Comments on the locking mechanism are mixed, including reports about whether the door latches properly, so take care to align the hardware during installation.

When it makes sense

The G99 plus suits a bedroom, office, or apartment door where managing access matters as much as having a key backup. Fingerprint and passcode entry give regular users alternatives to carrying a key, while app-based user management helps when access needs to be shared or updated. Its aluminum construction, multiple entry methods, and configurable modes make it a practical choice for people who want a smart door knob with flexible everyday access.
