Fingerprint Door Lock Smart Fingerprint Door Knob with App Control

Our review of the Fingerprint Door Lock shows it is best suited for homeowners or renters who want a compact, keyless solution for interior and light exterior doors. The single biggest reason to buy is its 3-in-1 access modes: fast fingerprint recognition, Bluetooth app control, and a conventional key backup, which together make it versatile for bedroom, apartment or office use. Installation is straightforward and the fingerprint unlock is often quick, though real-world performance can vary by user and fingerprint quality.

Key Features

• 3-in-1 access: Combines a thumbprint sensor, Bluetooth app control, and a physical key to offer flexible entry options depending on the situation.
• Three operating modes: Passage, entrance, and privacy modes switch by rotating the knob, providing simple control over access and privacy for rooms like bedrooms or offices.
• Fast fingerprint recognition: The lock claims sub-second recognition and stores up to 20 fingerprints for family members or trusted users.
• Local data storage: Fingerprint templates are stored locally on the unit rather than uploaded to the cloud to help protect user privacy.
• Rechargeable battery: A built-in 400mAh rechargeable battery charges in about 3 hours and includes a visual power display and low-battery alarm.
• App management: Bluetooth app control enables fingerprint management, unlocking records, and temporary access for guests while within Bluetooth range.

Who It's For

This lock fits people who want a compact keyless solution for interior doors such as bedrooms, home offices, apartments, and some garage doors where a simple retrofit is needed. It is especially handy for those who want to grant temporary access to guests or renters and prefer managing access from a smartphone.

People who need robust remote control beyond Bluetooth range, or who require heavy-duty exterior security for high-traffic exterior doors, should look elsewhere or add a separate Wi-Fi gateway. Also consider a different model if you need dozens of user profiles beyond the stated capacity of stored fingerprints.
