Your key is already on you.
Best for: keyless home entry, apartment security upgrades, and office access control without managing physical keys.
How many times have you stood at your door, hands full, digging through your bag for a key that's somewhere at the bottom? There's a simpler way to walk through your own door.
This smart door knob replaces your standard lock with a cleaner, more intuitive system. A quick fingerprint scan, a tap on your phone, or a backup key if you ever need it — and you're in. No fumbling, no worrying about who has a copy of your key, no locksmith calls when someone loses theirs.
Standard smart locks often require complex wiring or professional installation. This one doesn't. It fits most standard doors with a thickness between 33–55mm and installs without rewiring or drilling new holes — making it a practical upgrade for renters and homeowners alike.
Unlike basic electronic locks that rely solely on a keypad, this knob combines biometric fingerprint recognition with TUYA app control via Bluetooth, giving you multiple ways to manage access. Grant temporary access to a guest, check who came in, or lock up remotely — all from your phone.
What You'll Notice
Walking through your front door feels effortless. You stop thinking about keys entirely. And when someone needs access while you're away, you handle it in seconds from wherever you are — no spare key handoffs, no waiting around.
