Smart Main Door Lock

Digital PIN Code: The primary method of entry. You can set a master code and multiple user codes.
Smartphone App (Tuya/Smart Life): Unlock the padlock remotely via Mobile App
No Keys: Eliminates the problem of lost, copied, or stolen physical keys.

Waterproof (IP67 Rating): This is a standout feature. An IP67 rating means it is dust-tight and can be submerged in up to 1 meter of water for 30 minutes. This makes it suitable for harsh outdoor environments.
Reinforced Shackle: The U-shaped metal piece (shackle) is typically made of hardened steel, designed to resist cutting, sawing, and prying.

Tuya Smart Ecosystem: Connects to the Tuya or Smart Life app for comprehensive control.
Access Logs: The app keeps a history of who unlocked the lock and when, using their specific PIN.
Temporary & Scheduled Codes: Create codes that only work during specific time periods or for one-time use, perfect for granting temporary access to guests or workers.
Low Battery Alert: The app will notify you when the battery is running low.

Battery Powered: Typically uses standard, replaceable batteries like AA or AAA, offering a long battery life (often over a year with normal use).
Anti-Tamper Design: The keypad and internal mechanism are built to resist physical tampering and weather elements.
