Access Methods and Security Features

Fingerprint Recognition Technology
Fingerprint access provides quick, keyless entry without needing to remember codes or carry physical keys. This biometric method uses unique fingerprint patterns for identification, offering both convenience and personal security. The system is designed to work reliably within the specified operating temperature range of -20°C to 65°C, making it suitable for various indoor environments including heated spaces and cooler areas.Password Entry Systems
The independent version supports 1-8 digit numerical codes, allowing for customisable password complexity. This system enables multiple users to have individual access codes that can be changed regularly for enhanced security. The graffiti pass lock function takes this further by allowing temporary access codes to be created directly on the device interface - useful for granting one-time access to visitors, cleaners, or maintenance personnel without compromising permanent security settings.Traditional Key Backup
Despite its smart features, this lock includes traditional mechanical key access as a reliable backup option. This ensures entry is always possible even during power outages or electronic system maintenance. The mechanical components work alongside the electronic systems without interfering with smart functionality during normal operation.Connectivity and Control Options

Bluetooth Connectivity Versions
The Bluetooth-enabled versions, including the TTLock BLE and doodle board credit card Bluetooth variants, allow wireless control from compatible smartphones within range. This enables features like remote unlocking when approaching the door, access sharing with family members, and usage monitoring through dedicated mobile applications. These versions provide smart functionality without requiring additional gateway hardware.Wi-Fi Gateway Integration
For full remote access capabilities, the Wi-Fi gateway versions (including Tuya BLE and doodle board Wi-Fi variants) connect to home networks for internet-based control. This allows users to lock and unlock doors remotely via smartphone apps, receive notifications of access events, and integrate with broader smart home systems. These versions typically require connection to a compatible gateway device that bridges between the lock and home Wi-Fi network.Independent Standalone Operation
The basic independent version operates without wireless connectivity, functioning as a self-contained smart lock system. This version is ideal for users who prefer keyless access methods without smartphone integration or for installations where wireless signals might be problematic. It maintains all core access methods including fingerprint, password, and mechanical key while operating independently of network connectivity.Installation and Compatibility

Door Compatibility Requirements
This lock is designed specifically for wooden doors, making it suitable for most interior residential and office applications. The installation process typically involves replacing existing door hardware with the smart lock mechanism, requiring standard door preparation. While the source text doesn't specify exact door thickness requirements, these locks generally work with common door dimensions found in bedroom and office applications.Configuration and Setup Process
Setup varies by version but generally involves installing the physical hardware, enrolling initial administrator access methods (typically fingerprint and master password), and configuring any wireless connectivity if present. The independent versions focus on local setup while Bluetooth and Wi-Fi versions require additional mobile app configuration. All versions include the graffiti pass lock function for creating temporary access codes directly on the device interface.Environmental Considerations
With an operating temperature range of -20°C to 65°C, this lock is suitable for most indoor environments including heated spaces and potentially unheated areas like garages or storage rooms converted to offices. The electronic components are designed to function reliably within this range, though extreme temperature fluctuations should be avoided for optimal battery life and component longevity.
