This smart deadbolt lock with knob handle offers a comprehensive keyless entry solution for residential front doors.

Constructed from a zinc alloy body and a durable brushed nickel finish, the unit resists corrosion and wear, suitable for various weather conditions. The integrated fingerprint sensor uses capacitive scanning technology for quick and accurate user recognition, storing up to 50 fingerprints. The touchscreen keypad features backlit numbers for low-light visibility and supports up to 200 user codes. Tamper-resistant construction and an alarm lockout function after multiple incorrect attempts provide an additional layer of security. The lock connects via Bluetooth to a dedicated mobile application, allowing users to issue temporary passcodes remotely, view access logs, and adjust auto-lock timers. Powered by four AA batteries (included), the device offers low-battery alerts and a backup mechanical key override for emergencies. The auto-lock feature can be programmed to engage automatically after a set period, ensuring the door is never left unlocked unintentionally. The IP54 rating protects against dust and splashing water, making it reliable for covered outdoor installations. Installation is compatible with standard US door preparations—2-3/8" or 2-3/4" backset and 1-3/8" to 1-3/4" door thickness—and can be completed with a provided screwdriver in about 15 minutes. The lock operates smoothly with minimal friction, and the knob handle turns effortlessly to retract the latch. The app interface is intuitive, with clear menus for creating and revoking codes. Battery performance typically lasts several months under normal usage. The lock’s stability in maintaining connection and code storage is consistent. At its price point, this model delivers functional reliability without premium costs, offering a practical upgrade from traditional keyed locks. The absence of subscription fees for app features adds long-term value. The product is designed for homeowners and renters seeking convenient, secure access control without complex wiring or professional installation.
