This 5-in-1 WiFi smart fingerprint door knob lock combines keyless entry, remote access, and enhanced security in a single compact unit. Designed for bedrooms, offices, and interior spaces, it offers lock-side programming and local data storage to maintain privacy and responsiveness without relying on cloud services. The lock integrates a biometric fingerprint reader, a numeric keypad, a doorbell trigger, and a WiFi module that enables real-time alerts and remote unlock functions. Its solid zinc alloy construction and matte finish ensure durability and resistance to daily wear, while the compact knob profile fits standard door preparations without requiring additional wiring or hub. The lock’s fingerprint sensor utilizes capacitive scanning technology for quick and accurate recognition, storing up to 50 fingerprints locally. The backlit keypad allows code entry in low light, and the lock supports up to 100 user codes, making it suitable for shared offices or family use. The programming is performed directly on the lock via the keypad, eliminating the need for a separate app setup for basic functions. WiFi connectivity is established through a simple pairing process, and once connected, the lock sends push notifications to the user’s smartphone whenever the door is unlocked or locked. The doorbell-triggered remote unlock feature allows visitors to press the doorbell, and the owner can unlock the door from anywhere via the companion app. All data is stored locally on the lock, reducing latency and enhancing reliability. The lock operates on four AA batteries (included) and provides low-battery alerts through the keypad and app. The motor mechanism is designed for quiet operation, and the latch fits standard deadbolt or latch holes. Real-time alerts, such as incorrect password attempts or tamper notifications, are sent instantly to the user’s phone. The lock’s solid metal housing and precision internal components contribute to a long operational lifespan, and the fingerprint reader is coated with a scratch-resistant layer to maintain sensitivity over time. The price point of $34.00 positions this lock as a highly affordable smart access solution, offering features typically found in higher-priced models without compromising core functionality. This lock is ideal for homeowners, renters, and small office managers seeking convenient keyless entry and remote control without complex installation or ongoing subscriptions. The combination of fingerprint, keypad, and WiFi remote unlock covers multiple access scenarios, while the built-in doorbell adds an extra layer of convenience. The lock’s straightforward programming and local data storage make it suitable for environments where internet stability is variable.
