Full Smart Door Locks comparison in 2026

Updated August 2026
Data from Amazon and official Eufy and Wyze sites.
2026 verdict
Eufy FamiLock S3 Max wins on weather resistance, integrations, periodic passwords and its doorbell. It is rated IP65 versus IP53, spans HomeKit, SmartThings, Google, Alexa and Home Assistant via Matter, supports recurring guest passwords, and uniquely packs a 2K HDR video doorbell, camera with local storage and rear viewing screen alongside its palm-vein reader. Wyze Palm Lock answers with a lower price, a higher owner rating and longer battery life at about 6 months versus 4 with a dual-battery safety net, offering the same palm-vein convenience in a simpler package, though only Alexa and Google integrations and no video. Both auto-lock via gyroscope with anti-peep keypads and one-time codes. For the full entrance experience the Eufy FamiLock S3 Max takes the win; palm unlocking alone comes cheaper and better-rated from Wyze.
