Overview

Upgrade your entry with the HEI LIANG fingerprint door knob, a versatile smart lock designed for bedrooms, storage rooms, apartments, offices and hotels. This 3‑in‑1 design blends biometric access, app control and a concealed mechanical keyhole for reliable, keyless entry that fits modern living.

Biometric speed meets smart convenience

Unlock in about half a second with a precise fingerprint recognition engine. When you pair it with the encrypted app via WiFi or Bluetooth, you can remotely manage access, check unlock history, and switch between locking modes from anywhere in your home or property.

  • 0.5-second fingerprint unlock
  • Encrypted app control via WiFi or Bluetooth
  • Concealed mechanical keyhole for backup access

Durable design for everyday life

The handle sits in a 500-pound-class aluminum alloy frame, combining quiet operation with anti-pry strength. LED indicators confirm successful unlocks, while the slim, circular form suits various doors and interior aesthetics.

  • 500 lb impact-resistant aluminum alloy frame
  • Anti-pry design with visual unlock confirmation
  • Elegant round handle style with LED feedback

Smart security that travels with you

Manage who can enter and when. The lock stores up to 100 fingerprints, supports automatic locking after entry, and provides a secure activity log. You can create time-limited access codes (12 hours, 3 days, 1 week) for guests or staff. When network features are used, a gateway is required for WiFi connectivity.

  • Stores up to 100 fingerprints
  • Automatic locking and encrypted access log
  • Time-limited codes for visitors and staff

Simple setup, simple maintenance

Install on US standard doors with thickness between 1.18 and 2.17 inches. No wiring is required—just replace your existing knob using the included template and tools. A built-in 400 mAh battery recharges in 3 to 4 hours via USB-C, with a low-battery warning and a clear indicator.

  • Designed for US standard doors
  • No wiring required with quick replacement
  • Rechargeable battery with USB-C charging and low battery alert
