August Smart Lock 2nd Gen Silver
Score: 72/100
Yale Assure Lock
Score: 70/100Rankings
The August Home Smart Lock 2nd Generation is a retrofit smart lock that fits on the interior side of most single-cylinder deadbolts, preserving the existing key while adding app-based control. It requires a separate Wi-Fi bridge for remote access, which is a notable trade-off for users wanting immediate out-of-the-box connectivity. It is best suited for Apple HomeKit users and renters who want a non-destructive smart lock upgrade.
The Yale Assure Lock with Z-Wave is a keyless smart deadbolt that offers convenient PIN-based entry and remote control via Z-Wave hubs. Its primary limitation is the lack of physical key backup and strict protocol dependency, which may not suit all users. It is best suited for homeowners already invested in Z-Wave ecosystems who prefer keyless entry.

Professional reviewers stress the lock's easy, non-destructive installation, its retention of the original key, and its broad smart-home ecosystem support, especially HomeKit.
Everyday users highlight the convenience of eliminating key fumbling, the usefulness of virtual guest keys, and the peace of mind provided by activity logs.
Yale Assure is better for users willing to replace the whole lock and who want integrated Wi-Fi, but not ideal for renters needing a non-destructive retrofit.
