## Description

eufy Familock S3

Review: The eufy FamiLock S3 has been a huge upgrade for me, especially after returning the Lockin Veno. Assembly was surprisingly simple and frustration-free. Everything fit together intuitively, and the instructions were clear enough that I had the lock fully installed and running in far less time than I expected. What really sets the FamiLock S3 apart from the Veno is the feature set. The responsiveness of the fingerprint reader, the smoothness of the touchscreen, and the overall build quality all feel a step above. The app integration is cleaner too, with faster updates and more reliable notifications. After dealing with connection hiccups and slower response times on the Veno, this lock feels like a breath of fresh air. Another big draw for me was eufy’s strong security reputation. Their focus on privacy and local data processing gave me a lot more confidence in choosing a smart lock that would actually protect my home without sending data who-knows-where. It’s reassuring to know the company behind the product takes security seriously. Overall, the FamiLock S3 has been easy to set up, easy to use, and packed with thoughtful improvements over the lock it replaced. I’m genuinely glad I made the switch.
Review: Really cool lock. Works with my older and younger family (tested as young as 9 years old). the palm reading is insanely convenient. Recharging is a breeze, just a really good all around lock!

### ⭐⭐⭐⭐⭐ Review
*by A***R on 11 November 2025*

Impressed with all the options and features. UI Is a bit confusing tho and I do agree that the hands/vein technology is difficult to get to work. I’m gonna try creating multiple versions of my hands to see if that’ll improve things like I’ve done with the thumbprint one. Actually wishing I had the fingerprint one still. The video mechanism works great and you can choose different lengths to film, which I really like. I did feel that the battery could’ve lasted a bit longer. It lasted about a month before it needed recharging them but the four AA batteries held fine while it was being charged. This was with a lot of people coming in and out though. Np installing to door (although had my handyman do it). NOTE: after putting it together it will have u press a button in the back wheee the battery is and if u already put the cover on np bc it’s super easy to take off. I did have to try connecting a couple of times. If you have issues with this part and it talks about router settings go to your Internet provider settings online or app and change signal to 2.4 only from dual band (2.4 and 5.0) temporarily and then u won’t have a problem.
