This smart keypad door lock with handle combines fingerprint recognition, keyless entry, and a built-in doorbell into a single unit designed for front doors, bedrooms, and similar interior or exterior residential applications. The lock body is constructed from a zinc-alloy housing with a brushed finish, offering resistance to everyday wear and corrosion. The fingerprint sensor employs a capacitive semiconductor module that reads live finger ridges with a reported recognition speed of under 0.5 seconds. It can store up to 50 fingerprint profiles, making it suitable for households with multiple users. The backlit numeric keypad supports programmable entry codes, letting you assign temporary or permanent passcodes for guests, service personnel, or family members. The built-in doorbell eliminates the need for a separate wired or wireless bell unit, simplifying installation at the entry point. The lock is powered by four AA batteries, which are not included, and features a low-battery alert to prompt timely replacement. An external USB emergency charging port is available should battery depletion occur unexpectedly. The lock mechanism is a standard single-cylinder deadbolt design, compatible with most residential wooden or metal doors measuring 35 to 50 millimeters in thickness. The handle is ergonomically shaped for a comfortable grip, and the latch bolt has a brass core for smooth retraction.

Operationally, the lock functions with a simple touch or code entry, and the doorbell chime can be toggled on or off depending on user preference. The lock’s software supports an auxiliary app control function via Bluetooth, allowing remote management of access codes and user logs. The app interface is straightforward and does not require an internet connection for basic operation, though some advanced features may benefit from a paired smartphone. The lock finish is resistant to fingerprints and smudges, maintaining a clean appearance over time. This product is aimed at homeowners or renters who want a cost‑effective upgrade to keyless entry without sacrificing security. It offers a practical alternative to expensive smart locks, with straightforward installation that typically requires only a screwdriver. The unit does not rely on Wi‑Fi for core functions, reducing potential connectivity issues. The materials and assembly have passed basic durability tests, and the lock’s internal circuit board is sealed against dust ingress. While it is not marketed as a high‑security commercial lock, it meets standard residential safety expectations and provides a convenient way to manage access to a home or private room. The economical price of around 40 dollars positions it as a strong value proposition for budget‑conscious buyers seeking modern door security features.
