Sifely Fingerprint Smart Door Lock With Handle
The Sifely Smart Lock is designed for users who want a versatile keyless entry system without immediately investing in a connected smart-home setup.
The 3D fingerprint scanner is one of its biggest strengths, with recognition in under 0.3 seconds. Bluetooth connectivity allows users to manage access through the app, while an optional Sifely Wi-Fi Gateway can add remote management and Alexa or Google Assistant support.
ULTRALOQ Bolt Fingerprint WiFi Smart Lock With Handle
The ULTRALOQ Bolt Fingerprint comes with a biometric deadbolt, a matching handle, door sensor, and built-in 2.4GHz Wi-Fi.
Unlike the Sifely, users don't need to purchase a separate gateway for remote access. The companion app supports remote locking and unlocking, access logs, notifications, and user management.
Security is another major difference. The ULTRALOQ model carries a BHMA Grade AAA certification and includes an IP65-rated zinc alloy exterior.
Which smart lock is a better buy?
The Sifely Smart Lock is the better option for buyers who prioritise affordability, multiple access methods, and rental-friendly features. Its fingerprint scanner, key fobs, app controls, and optional gateway provide plenty of flexibility without requiring a fully connected setup from day one.
The ULTRALOQ Bolt Fingerprint is the stronger overall choice for users who want built-in Wi-Fi, advanced smart-home integration, stronger certified security, and door-status monitoring.
