Your Full Specs Overview


Multiple Unlock Methods for Your Door

Three-In-One Smart Door Lock

Our smart door lock offers three convenient unlock methods: fingerprint unlock, app control, and backup keys. This makes it the perfect keyless entry option. Before using fingerprint unlock, follow the manual steps in the app to set up your fingerprint. For battery charging, use a USB-A to Type-C cable (do not use a Type-C to Type-C cable).

Enhanced Security & Privacy

Security Design

Designed to bring you convenience and enhanced privacy, our smart door lock allows easy mode switching by rotating your fingerprint around the smart door knob. Modes include passage mode, entrance mode, and privacy mode. It’s perfect for bedroom doors to keep roommates or kids from entering your space.

Easy Installation

Quick and Simple

Installing our fingerprint door knob is straightforward. Use a screwdriver to install it in just minutes. It fits most US door thicknesses from 35 to 55mm and can be easily replaced with your existing door locks. Check the dimensions before purchasing. Detailed installation steps and videos are provided to ensure an easy setup.

Rechargeable Battery for Long Usage

Durability and Convenience

The K10 smart door knob features a built-in 400mAh rechargeable battery, providing 8-12 months of usage on a full charge. Charging takes 4-6 hours and only supports USB-A to Type-C cables. Fully charge the lock before first use. It also has a visual power display and a low-battery alarm to keep you informed. The battery is not removable and usage frequency can affect its lifespan.

Smart App Control for Greater Convenience

Remote Management

Our smart door lock offers a free app that allows you to add fingerprints, check unlock records, and set auto lock, passage mode, and privacy mode for a more convenient and secure experience. Control the lock within Bluetooth range. When the door knob is offline, you can first unlock it with your fingerprint and then reconnect it.
