    Product brochure and specifications for the Ultraloq UL3 BT — a Bluetooth-enabled fingerprint and touchscreen smart lever lock from U-tec.

    Overview

    The Ultraloq UL3 BT smart lever lock is a "RealKeyless" smart lock designed for maximum flexibility and convenience. Users can unlock with a fingerprint, code, mechanical key, or smartphone (Bluetooth 4.0 Low Energy). It supports "knock to open," letting the app detect a knock on the phone even while it's in a pocket. Designed for DIY installation — battery operated, no wiring, roughly 10 minutes to install.

    Key Features

    • Bluetooth 4.0 Low Energy Connectivity — unlock via the Ultraloq smartphone app, including "knock to open" without opening the app
    • Sense-On — touching the keypad or fingerprint reader automatically wakes and readies the lock
    • Advanced Fingerprint Identification — stores up to 95 fingerprints, identifies a user in under 0.5 seconds, works well for children and elderly users
    • Anti-Peep Touchscreen — 95 user-defined 4-8 digit codes with anti-peep technology (the lock still opens even if a randomized set of numbers is entered, as long as the correct code is somewhere in the sequence)
    • Up to 1 Year Battery Life — powered by 3 AA batteries, up to 8,000 access cycles, low battery alarm on app and display
    • Solid and Resistant — one-piece Zinc Alloy body, IP65 rated, waterproof and dustproof, suitable for indoor or outdoor installation
    • Intuitive OLED Display — walks users through adding/deleting users directly on the device
    • Hidden Backup Key — 3 mechanical backup keys, with the keyhole specially positioned on the bottom for extra security against keyhole hacking
    • Three Locking Modes — auto relock, privacy lockout, and free passage

    App Features

    • Keyless Entry — unlock the door directly from your smartphone
    • View Users — see who has access to the lock and how
    • Log Record — view a log of who entered and exactly when, from your smartphone
    • Clone — transfer all users to another lock in one shot when installing an additional Ultraloq
