310FK Fingerprint & Bluetooth Smart Door Knob for Keyless Entry

HIDALIFE 310FK 4-in-1 Keyless Entry Smart Lock Unlock your door in four ways: fingerprint, bluetooth, gateway, or key. Smart Control, Built for Everyday Convenience Set the auto-lock timer anywhere from 2 to 99 seconds and manage access right from your phone. Add, suspend, or remove users anytime, and check access history through the app. Smart Home & Voice Control Connect via Bluetooth or add a compatible gateway for more flexible smart home control. Through the Tuya/Smart Life app, you can pair the lock with Alexa and Google Assistant for convenient voice control. Gateway not included. 2.4GHz Wi-Fi only. Fast, Accurate Fingerprint Access Unlock your door in just 0.3 seconds with the high-precision fingerprint sensor, featuring over 99% recognition accuracy. Store up to 50 fingerprints for convenient access for family members, rental guests, or small office teams. Stay Powered, Even in an Emergency A low-battery alert lets you know when it’s time to replace the batteries, so you won’t get caught off guard. If the batteries run out, simply connect a USB-C power bank, phone, or laptop to the emergency power port for temporary power. Unlock the door and get back inside without the wait. Easy Passage Mode Switch between Auto-Lock and Passage Mode with a simple physical switch—no programming required. Just press the switch to choose whether the door locks automatically or stays unlocked, giving you flexible control for everyday use. Fits Standard U.S. Doors Designed to fit most standard U.S. doors with a 2-1/8" bore hole, 2-3/8" or 2-3/4" backset, and 1.37"–2" door thickness. Installation is quick and straightforward—just grab a screwdriver and install it in about 15 minutes, with no locksmith required. Fingerprint Tips for the Whole Family For children, seniors, or anyone with fingerprints that may change or wear down over time, we recommend re-enrolling fingerprints every few months for more reliable access. For seniors or users with worn fingerprints, registering multiple fingers can provide more flexible and consistent unlocking.
