DSJJBLL Fingerprint Door Lock – Smart Biometric Door Knob with App Control

Meet DSJJBLL Fingerprint Door Lock

Elevate your entry points with a biometric door lock designed for homes and small offices. This smart door knob blends seamless convenience with robust access control, offering modern keyless entry without sacrificing reliability. The result is a practical upgrade that fits busy households and private spaces alike.

Three modes for flexible access

• Passage mode allows temporary, hands-free passage when you need quick access without unlocking each time.
• Entrance mode grants entry for trusted users while keeping doors secured when not in use.
• Privacy mode locks the knob for bedrooms or home offices, preserving personal space.

Three-in-one convenience

• Smart door knob with fingerprint recognition for fast, keyless entry.
• App control to manage fingerprints, view unlocking activity, and switch modes remotely within Bluetooth range.
• Traditional key option as a reliable backup access method.

The device stores fingerprints locally (up to 20 profiles) and supports a 5-second auto-lock feature to deter unwanted entry. A clear visual power display and low-battery alarm help you stay informed. Privacy is prioritized through local storage rather than cloud uploads.

Battery life, installation, and compatibility

Powered by a rechargeable battery, the lock charges in just a few hours via a USB cable and is designed for straightforward DIY installation with a screwdriver. It fits most US doors, making an upgrade approachable for many homes.

Smart home readiness

Bluetooth app control enables convenient access management within range. For remote control or broader smart-home integration, a gateway can enable Wi‑Fi connectivity.

With its bold black finish, the DSJJBLL lock adds a modern, durable touch to entryways, pairing tactile feedback with practical performance for everyday use. This is an invitation to explore a more streamlined, private, and adaptable entry experience.
