Fingerprint Door Lock Smart Door Knob with App and Keypad - Keyless

In this review of the Fingerprint Door Lock smart door knob, the bottom line is simple: this unit is best for homeowners, apartment renters, and small offices that want a modern, hard-wearing replacement for a traditional knob with fast, flexible unlocking options. The reviewer found the lock delivers on convenience with keyless entry via fingerprint, code, or app, and it stands out for easy DIY installation and a sturdy zinc alloy build that feels more secure than many plastic alternatives.

Key Features

• Keyless Entry: Unlock with fingerprint, keypad code, or companion app for fast access without physical keys.
• Large Capacity: Stores up to 50 fingerprints and 50 password sets so families or teams can all have unique access.
• Fast Recognition: Fingerprint unlocks in about one second with a high recognition rate for everyday convenience.
• Durable Construction: The zinc alloy body provides solid protection and a heavier feel than typical consumer locks.
• App Control: Manage permissions, view entry logs, and set temporary passwords remotely when paired with a WiFi gateway.
• Auto Lock and Anti-Peep Code: Automatic locking reduces the risk of forgetting to lock, and anti-peep code options help protect password privacy.

Who It's For

This smart door knob is a good match for homeowners upgrading bedroom or interior doors, apartment residents who want keyless convenience without rewiring, and small hotel or office settings where multiple users need controlled access. It is particularly useful when you want a physical, secure-feeling lock with modern verification methods such as fingerprint and keypad.

It is less suitable for exterior doors that require certified weatherproof or high-security deadbolts, or for users who need an out-of-the-box WiFi connection, since remote app control requires an optional WiFi gateway accessory and batteries are not included.

Cons

• Remote app features require a separate WiFi gateway and batteries must be purchased separately.
• Size and fit received mixed feedback from some users, so confirm door compatibility before buying.
