This smart door lock with an integrated handle combines a sturdy zinc alloy housing with a smooth matte black finish, offering resistance to corrosion and daily wear. The built-in deadbolt mechanism is engineered for reliable operation, while the ergonomic handle design facilitates easy grip and turning. The keypad surface is treated with a fingerprint-resistant coating, helping maintain a clean appearance over time. Installation is compatible with standard US door preparations, and the lock fits doors from 1.375 to 2 inches thick, with an adjustable latch that accommodates both 2.375 and 2.75 inch backset options. The internal components are tested for over 200, 000 cycles, reflecting a focus on long-term durability. The lock provides five distinct entry methods: a capacitive fingerprint sensor that reads through minor skin moisture or debris; a backlit touchscreen keypad with responsive tactile feedback; a physical key override for backup access; and Tuya smart app control via Bluetooth and Wi-Fi, enabling remote lock/unlock and real-time status checks.

Additionally, a built-in doorbell function alerts users via the app when someone presses the button near the handle. The keypad automatically illuminates in low light, and the lock accepts up to 50 user codes and 50 fingerprints, suitable for households with multiple residents or frequent guests. Security features include an auto-lock timer that can be adjusted from 10 to 99 seconds, ensuring the door automatically secures after each entry. The lock also incorporates a tamper alarm that triggers after five consecutive incorrect attempts, deterring unauthorized access. Data transmission between the lock and the app is encrypted, and the device is certified to meet UL 294 and ANSI/BHMA Grade 2 standards for electronic locks. The deadbolt motor operates quietly and engages quickly, while the low-battery indicator provides ample warning before power depletion; in case of battery exhaustion, a 9V external contact can be used to temporarily power the lock. The Tuya app interface offers intuitive control, allowing users to generate temporary codes for guests, view access logs, and receive push notifications for lock activity. The lock operates on 4 AA alkaline batteries, with typical battery life ranging from 8 to 12 months depending on usage frequency. The overall construction feels solid without excessive weight, and the assembly requires no wiring or additional hub, making it a practical upgrade for home security. At a price that positions it as a value-oriented choice, this electronic front door lock delivers a balanced combination of convenience, reliability, and durable material selection for everyday use on residential entryways.
