Smart Lock ST380 Built-in Wi-Fi Fingerprint Keyless Entry - Reliable

Our review of the Smart Lock ST380 finds it best suited to homeowners and renters who want a modern, low-maintenance front door lock with strong remote features; the single biggest reason to buy is the built-in 2.4GHz Wi-Fi that enables real-time notifications and remote unlocking through the Smart Life/Tuya app. Installation is straightforward enough for DIYers, and the combination of fingerprint, passcode and app control makes day-to-day access convenient while maintaining secure control over who can enter.

Key Features

• Built-in Wi-Fi: 2.4GHz connectivity provides remote unlock, real-time status updates and temporary passcode management through the Smart Life/Tuya app for convenient offsite control.
• Multiple unlock options: Supports sensitive fingerprint unlocking, passcodes, app remote unlock, voice control via Alexa and Google Assistant, fob access and mechanical key entry for flexible daily use.
• High capacity user storage: Store up to 100 fingerprints and 50 passcodes so a household or small office can manage many users without running out of slots.
• Long battery life: Runs on 8 AA batteries for about 8 months of regular use and offers a power saving mode to extend life when needed.
• Weather resistant: IP56 waterproof rating and a wide operating temperature range let it handle exposed front door installations across seasons.
• Safety features: Includes auto-lock with adjustable delay, anti-peep passcode protection, emergency charging port and mute mode to fit different security and convenience needs.

Who It's For

The ST380 is aimed at people who want a smart deadbolt that integrates with a home ecosystem and offers multiple, convenient entry options; it is especially useful for busy households, short-term rental hosts and small offices that need temporary or remote access control. DIY installers will appreciate the advertised sub-15 minute install and compatibility with most US standard doors.

Those who need 5GHz Wi-Fi support, built-in rechargeable batteries, or a lock with a premium metal touchscreen should look elsewhere; likewise buyers who want biometric attendance tracking features beyond simple fingerprint access may find the feature set too basic.
