Score: 72/100Rankings
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 eufy Security Smart Lock C210 is a keyless entry deadbolt featuring built-in Wi-Fi and a touchscreen keypad, designed for easy retrofitting on standard US doors without requiring a separate hub. It offers five unlock methods, BHMA Grade 3 durability certification, and robust weather resistance, making it a reliable option for budget-conscious homeowners seeking remote access and multi-user management. Ideal for DIYers wanting quick install and basic remote/keyless access.
