KLLOQUE Fingerprint Door Lock – 3-in-1 Biometric Knob
The KLLOQUE smart door knob provides three modes: fingerprint, app control, and traditional keys. It supports passage, entrance, and privacy modes to tailor access for bedrooms or shared spaces. The accompanying app enables fingerprint management, unlock history, and remote-like control within Bluetooth range. For Wi‑Fi access, a gateway is required. This versatility makes it suitable for apartments, homes, or small offices seeking convenient biometric entry with fallbacks.
ThorBolt Fingerprint Door Knob with Keypad
ThorBolt combines fingerprint, keypad, and a physical key for flexible access. The auto-lock feature secures the door within five seconds of inactivity, while Anti-Peep technology helps conceal keystrokes when entering codes. The lock’s responsive fingerprint recognition and straightforward 4-step installation suit interior doors in homes, offices, or garages. A power-bank can be used via the Type-C port if batteries run low, making maintenance simple for busy spaces.
OFFTV Fingerprint Door Lock with Passcodes and APP
OFFTV’s 4-in-1 design blends fingerprint, password, two keys, and app control. It recognizes users quickly and offers 0.3-second fingerprint access with a 1-second door opening window. The 160×160 DIP fingerprint sensor expands recognition area for stability, while USB emergency charging provides a fallback when batteries drop. This makes it a practical option for bedrooms, offices, hotels, or short-term rentals seeking robust multi-factor access.
KLLOQUE Fingerprint Door Lock – Matte Black 4-in-1
This KLLOQUE model emphasizes four unlocking methods: fingerprint, password, app Bluetooth control, and backup keys. It offers auto-lock, passage mode, private mode, and an anti-peep keypad to prevent password peeking. It fits most American doors and lends itself to bedrooms or home offices where multiple access methods and remote access management via the app are valuable features for tenants or family members alike.
Sivmn Fingerprint Door Lock with Code
From the Sivmn line, this door lock supports keyless entry via fingerprint and code, plus app control and a handle-compatible design. It claims up to 50 fingerprints and 50 password sets, with one-second unlock times. The robust zinc alloy body and automatic locking help secure interior doors such as bedrooms or study rooms. Anti-peep code features protect against shoulder-surfing, making it suitable for homes or small offices that value strong on-device privacy.
Buying Guide
Key purchase considerations help you choose the right biometric lock for interior doors. First, unlock methods matter: four-in-one options with fingerprint, password, app, and key provide redundancy, while others emphasize app-based access only. Second, installation and compatibility: ensure the lock fits your door type (left- or right-handed) and mounting style, with straightforward installation for DIY projects. Third, security features: look for anti-peep keypads, auto-lock functionality, and local or offline data storage to protect privacy. Fourth, app and data handling: prefer locks that store biometric data locally rather than in the cloud to minimize privacy risk. Fifth, power options: most models use AA or AAA batteries; USB-C backup or power banks are helpful for uninterrupted access. Sixth, guest management: for rentals or shared spaces, consider temporary passes or time-limited codes. Finally, value and support: consider warranty length, customer support responsiveness, and the availability of gateway devices for Wi-Fi remote access.
From the options above, you can mix biometric convenience with practical backup options to tailor access for bedrooms, home offices, apartments, or small workplaces. Each model emphasizes ease of use, strong privacy protections, and flexible management to accommodate multiple users and scenarios.
