The INSMART Fingerprint Door Lock is a knob-style smart lock that opens four ways: fingerprint, passcode, mechanical key, or Bluetooth through the Tuya Smart app. It stores up to 100 fingerprints and 100 passcodes, which is generous for a knob lock and enough for a family, a small office, or a rental with rotating guests. Extras include auto-lock, passage mode, silent mode, temporary passcodes, a low-battery reminder, and USB emergency power. Against rival smart knobs, it leans on capacity and app control rather than a keypad screen or Wi-Fi, so it suits interior doors more than a front door that needs remote access.
