This fingerprint door lock with handle combines modern keyless entry technology with practical home security features.

Constructed from durable zinc alloy and reinforced ABS plastic, the lock body resists corrosion and everyday wear. The matte black finish provides a sleek appearance that complements both contemporary and traditional door styles. At its core, the biometric sensor rapidly captures and recognizes fingerprints, offering a convenient alternative to physical keys. The keypad is rated IP65, meaning it withstands rain, dust, and temperature fluctuations, making the unit suitable for front doors, side doors, and interior entrances. The lock stores up to 50 distinct fingerprints and 50 unique user codes, allowing household members, guests, or service personnel to gain entry without sharing a key. An accompanying mobile application (compatible with iOS and Android) enables remote management of user access, real-time monitoring of entry logs, and one-time or scheduled code generation. The auto-lock feature engages the deadbolt automatically after each closure, providing peace of mind for those who wish to secure the door without manual locking. The firmware is designed for stable operation, with minimal latency between fingerprint placement and bolt retraction. Hardware reliability is supported by a precision-engineered motor and a robust latch mechanism tested for thousands of cycles. Installation follows a standard deadbolt preparation, requiring only a screwdriver and a few minutes to replace existing locks on doors of standard thickness (1.38–2.17 inches). The included mounting hardware and clear manual facilitate a straightforward setup process. The lock operates on four AA batteries (not included), with a low-battery indicator on the keypad ensuring timely replacement. An external USB emergency port allows temporary power if batteries are depleted. This keyless solution is oriented toward homeowners, landlords, or tenants seeking an affordable upgrade to smart home security. The combination of fingerprint, code, and app access eliminates the inconvenience of lost keys while maintaining multiple layers of entry control. At a price point that emphasizes value, the lock delivers essential smart features without unnecessary complexity. Its weather-resistant construction and auto-locking capability make it particularly suitable for climates with rain, dust, or high humidity. The product supports a simple, secure daily routine for families, rental properties, or office interior doors.
