Product Description

The M5 Smart Fingerprint Door Lock is a practical, secure and user-friendly solution for bedrooms, offices and interior doors. Designed with multiple unlock options and advanced access control, it offers flexibility and reliability for households, offices and rental rooms.

The lock supports fingerprint access, password entry, IC card unlocking, Tuya Bluetooth connection and traditional mechanical keys. Through the Tuya App, users can generate temporary passwords, manage time-limited access, view unlock records, monitor battery status and configure user permissions. With support for up to 250 users, it is suitable for multi-user environments.

A semiconductor fingerprint sensor ensures rapid and accurate recognition, while the virtual password feature prevents password exposure by allowing random digits around the real code. Emergency power can be supplied through the USB-C port should the batteries run out, and mechanical keys offer an additional fail-safe option.

The M5 is designed for easy installation and fits most interior door thicknesses between 28–50 mm. Its durable aluminum and zinc alloy construction provides long-term strength and reliability.
