Key Features

• 0.3-SECOND FINGERPRINT UNLOCK - Fast, Accurate Biometric Access Every Time. Unlock in just 0.3 seconds with an upgraded biometric fingerprint sensor that recognizes your print even at different angles. Stores up to 100 fingerprints - ideal for families, roommates, and Airbnb guests. No keys to carry, no codes to remember. Customers consistently rate the biometric scanner as "reliable" and "works great every time."
• 4-IN-1 FLEXIBLE ACCESS - Fingerprint, Passcode, App & Key Backup. Multiple ways in, zero lockouts. Unlock with your fingerprint, touchscreen passcode, Home App, or backup mechanical key. Generate temporary or one-time passcodes for guests, cleaners, or service providers - and revoke access instantly when no longer needed. Perfect for Airbnb hosts and rental property owners.
• AUTO-LOCK + ANTI-PEEP KEYPAD - Always Secured, Always Private. Auto-lock activates the moment your door closes - so you never have to wonder if you forgot to lock up. The backlit anti-peep keypad lets you enter random digits before or after your real code, keeping your passcode safe from prying eyes. Real-time app notifications alert you every time the door is locked or unlocked.
• PRIVACY MODE & PASSAGE MODE - Total Control Over Your Space. Activate Privacy Mode from inside to instantly block all external access - ideal for bedrooms, home offices, or nurseries. Switch to Passage Mode to keep the door unlocked during household activities, moving, or entertaining guests. Two modes, one smart lock, complete control.
• LOCAL DATA STORAGE - Your Biometric Data Never Leaves Your Home. All fingerprint and access data is stored directly on the device - never uploaded to any server or cloud. No subscription fees, no data breach risks, no third-party access. Your privacy stays where it belongs: in your hands. Fully offline-capable even without Wi-Fi.
• 12-MONTH BATTERY LIFE + EMERGENCY BACKUP - Never Get Locked Out Powered by 4 AAA batteries for up to 12 months of typical daily use. Low battery alerts notify you in the app before power runs out. USB-C emergency port lets you power the lock temporarily if batteries die unexpectedly - because getting locked out is never an option.
