August Smart Lock 2nd Gen Silver
Score: 74/100
Ultraloq U-Bolt Pro
Score: 84/100Rankings

The Ultraloq U-Bolt Pro combines eight entry methods-including a 360° fingerprint sensor-with built-in 2.4 GHz Wi-Fi and an IP65-rated housing for robust outdoor use. Its battery life is shorter on Wi-Fi mode and the bulkier design can be challenging to install. Ideal for households seeking versatile biometric access and hub-free Wi-Fi control.

The August Home Smart Lock 2nd Generation is a retrofit lock that adds HomeKit, Alexa, and Google Assistant voice control while preserving the existing deadbolt key. Its main limitation is the need for an optional Wi-Fi bridge for remote access and the lack of a built-in Wi-Fi module. Best for Apple HomeKit users and renters who want smart features without replacing the whole lock.

Professional reviewers and editors, primarily from August's own product pages, stress the lock's easy, non-destructive installation, its retention of the original key, and its broad smart-home ecosystem support, especially HomeKit. They position it as a straightforward upgrade for users who want smart functionality without replacing their existing deadbolt.
Everyday users highlight the convenience of eliminating key fumbling, the usefulness of virtual guest keys, and the peace of mind provided by activity logs. No major recurring complaints appear in the available data, though users note the need for a separate Wi-Fi bridge and periodic battery changes.

“keypad, biometrics, and auto-lock FTW”




Professional reviewers commend the Ultraloq U-Bolt Pro for its unmatched versatility, noting the eight entry methods, reliable 360° fingerprint sensor, and the convenience of built-in WiFi that removes the need for a hub. The lock's ANSI Grade 1 certification, IP65 rating, and integrated door sensor are highlighted as strong security and usability features. Criticisms focus on the WiFi's 2.4 GHz limitation, the relatively short battery life of the WiFi model, and occasional finicky setup, as well as the bulkier form factor that may not suit every door.
Everyday users appreciate the easy installation, rapid fingerprint unlocking, and the ability to grant remote access to guests via eKeys. The door sensor's auto-lock function and the long-lasting AA batteries receive frequent praise. Common complaints revolve around fingerprint failures in wet or cold conditions, occasional app glitches during WiFi pairing, alignment challenges with the door sensor on warped doors, and a louder click compared with other smart locks.
