Smart Door Knob with Key & Keypad - Keyless Entry, Fingerprint

In this review the Smart Door Knob with Key & Keypad is evaluated for everyday home use and small offices; its biggest selling point is the combination of multiple reliable unlocking methods that remove the need for carrying keys while keeping access controlled. The unit supports fingerprint, password, IC card, mechanical key and Bluetooth app access, and stores data locally on a storage card rather than in the cloud, which will appeal to buyers concerned about remote data exposure. Installation is straightforward and the feature set targets convenience and privacy over flashy integrations.

Key Features

• Multiple Unlock Methods: Fingerprint, password, IC card, mechanical key and Bluetooth app provide flexible access options for different household members and situations.
• Local Storage: All fingerprints, passwords and IC card data are stored on an internal storage card to avoid cloud-based data risks.
• High-Capacity Access Control: Supports up to 100 fingerprints, 100 passwords and 100 IC cards, which works well for larger households or small office teams.
• Fast Biometric Recognition: Larger sensor module claims a recognition speed of about 0.5 seconds and a high recognition rate for quick entry.
• Auto and Emergency Features: Auto-locking, anti-peeping password entry, silent mode, low battery reminder and a Type-C emergency power supply add practical reliability.
• Easy Installation: No drilling or wiring required; fits most standard wood doors 1.18 in to 1.97 in thick and installs with a small screwdriver and video guidance.

Who It's For

This smart door knob is aimed at homeowners, apartment renters and small office managers who want keyless entry without relying on cloud accounts and who need a mix of unlocking options for different users. It is particularly useful where local data storage and multiple credential types matter.

Those who need deep native automation without adding a gateway, or who require professional-grade commercial locks, should look elsewhere; while the lock can integrate with broader smart home systems through an added gateway, it is primarily a consumer residential solution.

Pros & Cons

Pros

• Multiple unlocking methods increase convenience and redundancy when one method is unavailable.
• Local storage of credentials reduces exposure to cloud data leaks and privacy concerns.
• Wide credential capacity supports families and small teams without frequent reprogramming.
• Simple, non-destructive installation fits most residential doors and includes video help.

Cons

• Some users report mixed reliability with the mobile app and periodic battery drain requiring frequent replacement.
• Auto-lock is fixed to engage after closing, which may not suit users who prefer to leave doors unlocked on occasion.
