This fingerprint door lock combines biometric recognition, a touch keypad, and smart app control into a single, streamlined unit. The K10plus model features a matte black finish that resists smudges and blends with various door styles. The lock body is constructed from durable zinc alloy, providing reliable protection against forced entry and daily wear.

Inside, the capacitive fingerprint sensor uses high‑resolution scanning to read finger details accurately and quickly, while the keypad enables entry via personalized codes. The app allows remote monitoring and lock status updates, and the auto‑lock function engages after a preset period, offering convenience without manual checking. All hardware components are designed for consistent performance across temperature changes and moderate humidity, making the unit suitable for indoor use in bedrooms, offices, or private entrances. The lock operates on standard AA batteries, and a low‑battery alert is sent through the app to ensure uninterrupted use. With its thoughtful engineering, this keyless door knob delivers a reliable balance of security and ease for everyday access. The product’s manufacturing process includes quality checks on the sensor alignment, circuit board stability, and keypad responsiveness, which contribute to the lock’s overall dependability. The auto‑lock function can be adjusted via the app, allowing users to set the delay from one to ten seconds, reducing the chance of accidental locking. The keypad illuminates for visibility in dim light, and the tactile feedback of the buttons provides a clear confirmation of each press. The fingerprint sensor can store up to 50 unique fingerprints, making it suitable for small households or shared spaces where multiple users need quick access. The app interface is straightforward and supports both iOS and Android devices, and no subscription is required for basic functionality. These details reflect a product that is thoughtfully assembled with user‑focused features. The finish on the lock is resistant to fingerprints and corrosion, helping maintain a clean appearance over time. The lock’s mechanical components are tested to withstand repeated use without jamming, and the motor that drives the latch operates quietly.

Additionally, the included screw covers and alignment guides simplify installation on standard doors (1⅜ to 1¾ inches thick). The overall design keeps a low profile while delivering essential smart‑lock capabilities at a very affordable price point. This product suits individuals seeking a dependable entry solution for interior doors where minimal upkeep and quick access are priorities.
