Three flexible unlock methods

This model supports fingerprint unlock, remote App control, and traditional physical keys. Whether you’re rushing out the door, welcoming a guest, or coordinating entry for a cleaning crew, you have multiple options that adapt to your routine without compromising security.

• Fingerprint unlock via a 360° sensor for quick, hands-free entry.
• App control through the TT LOCK app to manage users, access history, and settings.
• Backup physical keys for times when screens or devices aren’t available.

Speed, privacy, and smart features

Biometric access is designed to respond rapidly, with a 0.1-second recognition window, and up to 100 fingerprints can be stored locally. The lock also lets you set auto-lock, privacy mode, and a dedicated passage mode, giving you control over when and how entry is allowed. Importantly, fingerprints and in-app data stay on the device, minimizing reliance on cloud storage and supporting privacy-conscious use.

• 0.1-second biometric recognition for smooth entry.
• Local data storage keeps personal information private.
• Auto-lock, passage, and privacy modes offer flexible security states.

Durable design and straightforward installation

Constructed from premium zinc alloy with a weather-resistant finish, the knob is built to withstand daily use and occasional exposure to the elements. A screwdriver is all you need for a typically quick installation—often under 15 minutes—making it suitable for bedrooms, cloaks, apartments, and small offices.

• Sturdy metal alloy construction with enhanced security features.
• Sweat and weatherproof for reliable performance in real-world conditions.
• Simple, tool-assisted installation that takes minutes rather than hours.
