Fingerprint Door Lock Smart Door Knob - Keyless Entry & App Control

Our review of the SOOWAY Fingerprint Door Lock finds it best suited for homeowners and renters who want a straightforward upgrade to bedroom, garage, office or pantry doors without rewiring. The bottom line: this smart door knob delivers quick biometric access and simple Bluetooth app control, making everyday entry faster and more secure. Setup is mostly screwdriver-easy for U.S. standard doors, and the fingerprint sensor unlocks in about 1s while an auto-lock feature secures the door after 5s.

Key Features

• 3-in-1 unlocking: Fingerprint, Bluetooth app control and two physical keys provide flexible entry options to match different habits and emergencies.
• Fast fingerprint unlock: The biometric sensor registers and unlocks within about 1s and supports up to 100 fingerprints for full family access.
• Bluetooth app management: The Tuya-compatible app lets an administrator authorize users, review operation records and unlock within Bluetooth range.
• Auto lock and mute mode: The knob relocks automatically after 5s and offers a silent mode to eliminate audible feedback when needed.
• Easy installation: Designed for U.S. standard backset sizes 2-3/8' and 2-3/4' and door thicknesses 1-3/8' to 2-1/8', it installs with a screwdriver and the included manual.
• Emergency and privacy options: Mechanical keys provide emergency power access while private mode restricts entry for added peace of mind.

Who It's For

This smart door knob is ideal for people upgrading interior doors where keyless convenience and quick biometric access matter-parents securing a pantry, renters who cannot rekey entire locks, or homeowners adding smart access to non-exterior doors. It fits a range of U.S. standard doors and suits families because it stores many fingerprints for easy multi-user access.

Those who need fully remote cloud control or long-range Wi-Fi access should look elsewhere, since the app control works via Bluetooth only. Also, buyers who require heavy-duty exterior security features or commercial-grade certification may prefer a higher-security deadbolt solution.

Frequently Asked Questions

App couldn't find my door lock, what should I do?
If the app cannot find the lock, ensure batteries are installed, then reset the lock using the setting button on the interior knob and add a Bluetooth administrator before pairing.

Why won't the lock recognize my fingerprint consistently?
When recording fingerprints, place a clean, dry finger at multiple angles so a larger area is scanned; re-registering fingerprints often improves recognition.

Does the app work remotely?
No, the app connects via Bluetooth only, so direct remote unlocking from outside Bluetooth range is not supported without additional hardware.
