Built for everyday use: high-quality aluminum alloy construction provides wear resistance and long-term reliable performance while maintaining a sleek appearance. Remote control and monitoring: TTlock app compatibility lets you manage access permissions, view lock activity, and control the lock from your smartphone. Features and performance 4-in-1 access: biometric fingerprint for quick entry, PIN code for shared access, smartphone control via TTlock app for remote management, and a mechanical key for emergency use. Durable material: crafted from aluminum alloy to resist wear from daily use and maintain consistent operation over time. Automatic magnetic locking: smooth, silent latching that minimizes noise and prevents slamming while securing the door.
