Eufy FamiLock S3 Max vs Nuki Smart Lock Go

Eufy FamiLock S3 Max wins with its higher rating, IP65 build, integrated video doorbell and camera, palm-vein entry and guest password features. Nuki Smart Lock Go counters with a far lower price, 2-year warranty and effortless European-cylinder retrofit.

Scope. The Eufy replaces lock, doorbell and porch camera in one device with a rear screen as a digital peephole. The Nuki is a minimalist interior motor that smartens your existing Euro cylinder, with keypad and fingerprint sold separately and remote access as a paid add-on.

The Eufy FamiLock S3 Max installs on standard doors as a full lock replacement with an IP65 exterior. The Nuki Smart Lock Go clips over a European profile cylinder indoors and is not weather-resistant.

The Eufy FamiLock S3 Max offers palm-vein recognition, keypad codes, app and physical key. The Nuki Smart Lock Go offers phone, watch and geolocation auto-unlock out of the box, adding keypad or fingerprint only via accessories.

Choose Eufy FamiLock S3 Max to consolidate your entrance: palm unlock in any weather, 2K video with no monthly fees, and a rear screen the family checks before opening, all better-rated than the Nuki.

Choose Nuki Smart Lock Go for the cheapest quality path to a smart Euro-cylinder door: ten-minute install, auto-unlock as you arrive, Matter support and a 2-year warranty.
