Fingerprint Door Lock Smart Door Knob - Keyless Biometric Entry

In this review of the Fingerprint Door Lock smart door knob, the bottom line is simple: it is a practical, keyless upgrade for homes, apartments and guest rooms that prioritizes convenience and multiple access options. The single biggest reason to buy is the combination of fast fingerprint recognition with app control, so everyday entry becomes quicker and less fussy than carrying keys. Installation is straightforward for standard US doors and the Tuya Bluetooth app adds remote management and temporary codes without subscription fees.

Key Features

• 5 Multiple Ways To Unlock: Offers fingerprint, passcode, Tuya app control, IC card and physical key access so there are backup options for every situation.
• Tuya APP Smart Control: Manage users, share e-codes and check lock logs from the Bluetooth app without recurring charges, making remote management simple.
• Fingerprint Quick Unlock: One-touch fingerprint access unlocks in about 0.2 seconds with an advertised high recognition rate for fast daily use.
• Auto-Lock & Anti-Lock: Configurable auto-lock that engages after 5s and an admin-only anti-lock for extra privacy and security when needed.
• Capacity: Stores over 50 fingerprints and up to 100 IC cards, which is useful for households, offices or short-term rentals.
• Voice Guide Easy Installation: Designed for most US left- or right-handed doors and installs without drilling, guided by voice prompts for simpler setup.

Who It's For

This lock is aimed at homeowners, renters with compatible doors, and hosts managing short-term rentals who want a combination of biometric convenience and app-based code sharing. Its multiple user capacity and IC card support make it suitable for small offices or apartments where several people need access.

It is less suitable for doors that do not match standard US dimensions or for buyers who require a WiFi-connected solution or cloud-based remote unlocking, since the unit relies on Bluetooth through the Tuya app and has no built-in WiFi or subscription services.
