This smart door lock replaces traditional interior door hardware with an electronic access system designed specifically for wooden doors in residential and office settings. Its single spherical handle offers a modern, simplified aesthetic while housing advanced unlocking technologies including fingerprint recognition, password entry via a graffiti-style pass lock, physical key backup, and remote app control. The lock operates effectively within a wide temperature range from -20°C to 65°C, making it suitable for most indoor environments. Available in multiple configurations to suit different connectivity needs, it provides a practical upgrade for securing bedroom doors, office doors, and other interior access points without requiring complex wiring or major door modifications.

Features and Construction

This electronic lock integrates several access methods into a single spherical handle unit designed for straightforward installation on standard wooden doors. The construction combines a mechanical locking mechanism with electronic control components to provide reliability across different access scenarios.

Material and Build

The lock incorporates metal components for the physical locking mechanism alongside electronic circuits for fingerprint scanning, password processing, and wireless communication. The spherical handle design provides a distinct visual profile compared to conventional lever handles, contributing to its modern simplicity aesthetic. The integration of multiple access technologies into this single form factor allows users to choose their preferred unlocking method while maintaining a clean, unified appearance on the door.

Size and Practical Fit

Designed specifically for wooden interior doors, this smart lock fits standard door preparations typically used for bedroom and office doors. The spherical handle configuration requires appropriate clearance for hand operation but follows conventional single-handle installation patterns. While exact dimensions are not specified, the product is engineered as a direct replacement for existing single-handle locksets on wooden doors, making it compatible with most interior door applications without requiring specialised door modifications or unusual cutouts.

Uses and Placement

This smart lock serves as a primary access control point for interior spaces where traditional keys are inconvenient or where multiple users require access. Its temperature tolerance from -20°C to 65°C ensures reliable operation in various indoor climates, from heated offices to occasionally unheated storage areas.

Event or Professional Use

In office environments, the multiple access methods allow different staff members to use fingerprint, personalised passwords, or shared codes without distributing physical keys. The graffiti pass lock function enables temporary access codes for visitors or maintenance personnel that can be easily changed afterward. Bluetooth and Wi-Fi gateway versions provide facility managers with remote access logs and the ability to grant or revoke permissions without physical presence, supporting managed access control in multi-user professional settings.

Everyday Home Use

For residential applications like bedroom doors, bathroom doors, or home offices, the fingerprint recognition offers quick, keyless entry for regular users while password access accommodates guests or family members. The physical key backup ensures access during power outages or electronic system maintenance. The modern simple style complements contemporary interior design while providing enhanced security over basic passage locksets, making it suitable for homes seeking upgraded interior door security without the complexity of full home security systems.

Benefits and Buying Value

This smart lock provides an intermediate security solution between basic mechanical locks and fully integrated smart home systems, focusing specifically on interior wooden door applications where wiring may be impractical or unnecessary.

Reuse and Low Maintenance

The lock's multiple access methods reduce wear on any single component, as users can alternate between fingerprint, password, and key entry. Electronic components operate within their specified temperature range without requiring climate control, and the mechanical key backup ensures functionality even if electronic systems require service. Available configurations allow selection based on specific needs—choosing independent versions for standalone operation or gateway versions for integrated remote management—providing flexibility without paying for unnecessary connectivity features.

Why Choose This Product
