Fuliko Biometric Fingerprint Door Knob — App & Key Access, Thumb-Operated 3-Mode Lock for Bedrooms and Entry Doors

Secure your home or office with the Fuliko biometric knob that recognizes thumbprints and supports both app and mechanical key access. Rotate with your thumb to switch among three modes — passage, entrance, and privacy — to protect bedrooms and other private spaces. This 3-in-1 security knob combines traditional knob convenience, app-based controls, and key backup for reliable everyday use. It stores up to 50 fingerprints locally and includes automatic locking and low-battery alerts to keep access smooth and safe. Manage users and operate the lock remotely within Bluetooth range via the companion app (WI- option available separately). Power comes from a 400mAh USB-rechargeable battery, and installation is straightforward with a screwdriver on most US doors. Please check size before purchase.
