Evanshow 4-IN-1 Fingerprint Door Lock

The Evanshow 4-IN-1 smart lock combines fingerprint, keypad password, two mechanical keys, and IC card access. It supports storing up to 100 fingerprints and 50 passwords to accommodate family members and guests. An administrator fingerprint is required before first use to prevent unauthorized access. A USB emergency power port offers a workaround if batteries run low, though it cannot charge the internal cells. The sensor delivers quick, sub-second recognition for efficient entry. Ideal for bedrooms, home offices, and hotel rooms where flexible access is valued.
Evanshow 4-IN-1 Fingerprint Door Lock (Second Variant)

This Evanshow model mirrors the 4-IN-1 approach with fingerprint, password, keys, and IC card options. It emphasizes a rapid 0.5-second fingerprint check and broad accessibility for households with multiple residents or guests. The device supports emergency power via USB and is targeted at front doors as well as interior entries like bedrooms and offices. The initial admin setup remains essential to secure operation, preventing unwanted unlock attempts during setup.
KLLOQUE 3-IN-1 Biometric Door Knob

The KLLOQUE 3-IN-1 model blends fingerprint, app control, and traditional keys for versatile access. It supports mode switching through the knob and offers a privacy mode, entrance mode, and passage mode. The accompanying app facilitates fingerprint enrollment, unlock history viewing, and access management, with Bluetooth-based control within range. For larger spaces like apartments or hotels, this lock provides a balanced mix of offline and app-driven access control without requiring extra gateway hardware for basic use.
KLLOQUE 4-in-1 Smart Door Knob

This 4-in-1 option from KLLOQUE adds an app-controlled layer to fingerprint, password, and mechanical key access. It features automatic locking, a mode selection system (passage, normal, privacy, silent), and detailed user management through the app. The device supports Bluetooth for local control and notes that remote (Wi-Fi) control may require an additional gateway. It is designed to fit US standard doors and is suitable for bedrooms, offices, and entryways where flexible control and recording of access events are important.
Zengtumy Fingerprint Door Lock

The Zengtumy lock supports four unlock methods: fingerprint, password, mechanical keys, and IC card. It stores up to 100 fingerprints and provides auto-lock for enhanced security, ensuring the door locks automatically after closing. The 0.3-second biometric recognition keeps entry smooth, making it suitable for bedrooms, apartments, and office entrances where quick access and reliable security are required. It’s appropriate for users seeking a robust, multi-method biometric solution without extensive additional hardware.
Buying Guide: Key Purchase Considerations
When evaluating biometric door locks, consider how you balance convenience, security, installation, and future-proofing. Important factors include sensor performance, enrollment capacity, backup access methods, and app ecosystem. If you share doors with guests or family members, a model with higher fingerprint and code capacity reduces management friction.
Unlock methods and user management are critical. Four-in-1 and 5-in-1 models offer redundancy—fingerprint, passcode, keys, IC card, and app control—yet may require more setup time and occasional firmware updates. For strict privacy needs, look for modes like privacy or silent mode, plus a clear log of access events.
Ease of installation and compatibility with US standard doors matter for DIY installations. Check backset measurements, door thickness compatibility, and handedness. Bluetooth-based app control is convenient within range, but consider whether you need remote access via a gateway or dedicated hub for Wi-Fi connectivity.
Power and reliability are also essential. Most locks include a USB emergency power port; remember batteries are still required, and constant power is not guaranteed by USB charging. Review the device’s battery life, alert features for low power, and the availability of customer support to address installation or operation questions.
Price and value considerations vary by feature set. If you require extensive administrator control, event logs, and temporary access codes for guests or deliveries, prioritize models with robust app features and straightforward enrollment processes. For high-traffic homes or small offices, a combination of fingerprint capacity and secure offline modes provides durable, user-friendly security.
