    Upgrade your entryway with the FM-308, an electronic front door lock designed to fit a wide range of doors. Unlike many competitors that lock you into one specific mortise type, this smart house lock is compatible with multiple mortise designs – making installation easier and more flexible. A multi-language version is also available, perfect for international markets or homes with multilingual users.

    The FM-308 works seamlessly with both TTLock and Tuya apps. TTLock connects via Bluetooth BLE and supports remote access when paired with a gateway, plus Google Home and Alexa in select countries including the USA, Australia, Canada, India, the UK, France, Italy, and Brazil. Tuya offers built-in Wi-Fi for direct internet connection. As a smart home lock, it puts access control in your pocket – lock or unlock remotely, manage access schedules, and view the audit trail to see who opened the door and when.

    Built from aluminum alloy with a tempered glass screen and spray painting finish, this electronic front door lock is tested to 100,000 unlock cycles with 98-hour salt spray protection. It fits door thickness from 35mm to 55mm and operates in temperatures from -20°C to 60°C – handling both cold winters and hot summers with ease.

    Stop carrying keys. The FM-308 offers five ways to unlock: smartphone, fingerprint, password, RFID card, and a mechanical backup key for emergencies. The fingerprint sensor provides instant one-touch access, while the anti-peep scramble code protects your password from prying eyes. You can share permanent or temporary eKeys with family members, guests, or service providers through the app.

    Security features include incorrect attempt lockout, double verification mode, and a privacy switch that locks out all access except the administrator and override key. Low battery alerts and a Type-C port for emergency power ensure you are never locked out. Whether you need a smart house lock for your front door or a smart home lock for a rental property, the FM-308 delivers flexibility, security, and peace of mind.
