Built with user-friendly installation in mind, it supports automatic recognition of left or right-handed doors and operates reliably in extreme temperatures. Whether you’re rushing out the door or returning home late, this lock ensures peace of mind through anti-peeping technology, auto-lock functionality, and robust construction.

Key Features

• Passcode Entry with Backlit Keypad: Features a responsive, illuminated keypad that supports up to 300 unique user codes, allowing family members or guests to enter securely without sharing keys. The backup option includes two mechanical keys for emergency access.
• Auto Lock & One-Touch Locking: Customize the auto-lock timer between 5 to 60 seconds after the door closes—perfect for those who often forget to manually secure the lock. Alternatively, press and hold the “lock/unlock” button for three seconds to instantly engage the deadbolt.
• Anti-Peeping Password Technology: Enhance privacy by adding random digits before or after your actual code when unlocking. This feature masks your real password from onlookers while still granting access, ensuring confidential entry even in public view.
• Anti-Lock Function & Privacy Mode: Includes an anti-lock mechanism on the interior side to prevent forced entry attempts. When activated, it blocks external operation until unlocked from inside, giving you full control over your space.
• Voice Navigation Support: Guides users during setup and daily use through clear audio prompts in multiple languages, making operation intuitive even for first-time smart lock users.
• Durable Weather-Resistant Design: Engineered to function reliably outdoors with an IP56 waterproof rating and operating range from -22°F to 176°F (-30°C to 80°C), suitable for both indoor and outdoor installations.
• Easy Installation with Auto-Detection: Compatible with most standard US doors (left or right-handed) thanks to its 180° adjustable design. The system automatically detects door orientation without requiring manual configuration.
• Long-Lasting Battery Life: Powered by four AA batteries (not included), providing over one year of use with typical household activity. A low-battery alert notifies you when power is running low.
