Fingerprint Smart Lever Lock with one touch Keyless Entry fits US Knob & Lever FM820

"Stop fumbling for keys or typing codes. This fingerprint smart lever lock gives you instant one-touch access – just press your finger and the door opens. Designed for the US market, it directly replaces your existing knob or lever locks with no additional drilling. The easy DIY retrofit fits standard American door thickness (35-65mm) and takes minutes, not hours.

While fingerprint is the fastest way in, you still have four backup options: PIN codes, RFID cards, app-based eKeys, and a mechanical key. This makes it easy to share access with family members who prefer a code, or guests who only need a temporary eKey. Choose between TTLock (Bluetooth BLE with optional gateway) or Tuya (built-in Wi-Fi). Both apps let you lock or unlock remotely, manage access schedules, and view the audit trail to see who came and went.

Built for real-world use, this lock is tested to 100,000 unlock cycles and CE certified. Security features include incorrect attempt lockout, anti-peep scramble code, double verification, and tamper alarm. Low battery alerts and a Micro USB port for emergency power ensure you are never locked out. Passage mode lets you keep the door unlocked during business hours.

For Airbnb hosts, property managers, or busy families, fingerprint access is a game changer. No more worrying about guests losing keys or forgetting codes. And because this functions as a digital door handle, you can manage every entry remotely, grant temporary access to cleaners or repairmen, and eliminate physical keys for good.
