Product Details

• Color:Satin Nickel
• Specific Uses For Product:"Cleaning/Maintenance Visits Temporary visits: Generate a one-time passcode (4 digits) that automatically expires after a single use. Regular visits (e.g., weekly cleaning): Assign a dedicated user passcode and delete it after the service is completed. Gatherings/Parties Slide the switch on the interior panel to ""ON"" (Passage Mode) to keep the door unlocked, allowing guests to enter and exit freely. Slide it back to ""OFF"" after the event to restore automatic locking. Courier/Food Delivery When you cannot open the door in person, generate a one-time passcode and share it with the delivery person via phone or text; it expires after one use. Short-term Rentals/Homestays Before new guests arrive: Delete all passcodes from the previous guests and assign exclusive passcodes to the new guests (these can be linked to the room number or check-in date). Simply delete the passcode after checkout; there is no need to replace the lock cylinder or return physical keys.", "Daily Family Use Parents: Register fingerprints from your most frequently used fingers for the quickest daily unlocking method. It is recommended to register 1–2 fingers per person as a backup. Children under 12: Register fingerprints and update them every 3–6 months; as children's fingers change during growth, regular updates ensure smooth recognition. Seniors: It is recommended to register 2–3 fingers (e.g., thumb and index finger). Since fingerprints may become fainter with age, registering multiple fingers increases the success rate. If recognition is difficult, a passcode can be used instead.", "Fingerprint Care When registering a fingerprint, ensure your finger is clean and dry. Align the center of your fingerprint with the center of the sensor and hold it steady until you hear a ""beep."" If the sensor surface has oil or dust, gently wipe it with a soft, dry cloth to improve recognition accuracy. If your fingers are dry or cracked, lightly moisten them before attempting recognition."
