Bluetooth routing streams status alerts straight to your paired smartphone. The sturdy knob style blends into contemporary rentals. Brushed-aluminum surface blocks daily scratches. Customizable thresholds let you adjust sensitivity to match household habits.
Battery cavity accepts four standard AAA alkaline units. Certified for safety through CE, FCC, RoHS, and weee standards. Avoidance of high-concern chemicals keeps air clean behind doors. Model D2 ships verified from Mainland manufacturing channels.
The sealed box delivers the aluminum lock assembly, stainless mounting screws, alignment plate, printed guide, and two backup mechanical keys for fallback.
Position the lock body over your chosen door edge. Fasten the backing plate with provided hardware. Slide in four AAA alkaline batteries and watch the panel awake. Open the Tuya application, select Bluetooth pairing, and enroll your primary fingerprints. Save your desired keypad code and test the quiet turn.
You reclaim morning minutes lost to key hunting while securing personal spaces. Remote app views confirm exact closure times without guessing. Spare mechanical keys override rare power drops. Polished casing maintains showroom shine throughout long service years.
Engineered for bathroom privacy doors, master bedroom suites, detached garden studios, shared hallway upgrades, and quiet study rooms demanding soft engagement.
Designed for apartment residents and leaseholders who want modern access without deep exterior drilling. Suits property managers updating vacant flats and households simplifying shared corridor traffic.
Can I mount this on an exterior entrance? No, the internal-grade housing lacks weatherproof seals and must stay indoors.
Does the silent feature affect locking strength? Motor torque remains fully unchanged while the acoustic dampener removes audible clicking.
