Eufy FamiLock S3 Max vs Google Nest x Yale Lock

Full Smart Door Locks comparison in 2026

Updated August 2026
Data from Amazon and official Eufy and Google sites.
2026 verdict
In the world of smart locks, few products try to do as much as the Eufy FamiLock S3 Max, and against the Google Nest x Yale Lock that ambition pays off. It carries a higher owner rating, adds an IP65 weather rating the Nest lock lacks, and folds in a built-in 2K HDR video doorbell with local storage and a rear screen that doubles as a digital peephole, on top of broader platform integrations, one-time and anti-peep passwords, and palm-vein recognition alongside a physical key. The Google Nest x Yale Lock isn't left with nothing: it costs less, carries a longer two-year warranty, and its per-user code logging remains a strong reason to choose it. But once you weigh a lock-doorbell-camera combo against a keypad-only deadbolt tied to one ecosystem, the FamiLock S3 Max is simply built for more households.
