eufy FamiLock S3 Max Smart Lock with Palm Vein Recognition – Keyless Entry Door Lock for Front Door, 3-in-1 Wi-Fi Keypad Deadbolt+ 2K HDR Camera+ Doorbell, ANSI/BHMA Grade 1, Rear Lock Video Screen

UPDATE: Turned out GREAT! You *CAN* duplicate keys and it offers so much smarts!
This product turned out to be ***really impressive**** and great!It’s a unique marvel of multiple products in one device: smart lock with keypad, palm reading, physical key, connected doorbell, digital peephole AND security camera with AI.If you struggle to record your hands, I have a suggestion. See video (uploaded low res for privacy). Start with your fingers on the sensor at the same angle of the palm reader (top of device) and slowly raise your hand while keeping the same angle vs the reader. At some point it will register/recognize it. This process became super simple for the whole family to register all hands. At the location it recognizes the palm you can then make a mark on the door frame with a pencil to help you remember the exact location and angle to use next time. Simple and easy.Also, I read information on the product page, and some reviews likely repeating the page info, that you cannot duplicate the keys “for security reasons”. ***BUT*** it turns out you can copy the keys as I did at the local hardware store, nothing different to other keys out there. This may seem like an issue but for us it was crucial to have the reassurance that we can each have a physical key to open the lock in an emergency if the battery or motor fails (it hasn’t). So yes you can easily copy the keys  (they include 2 with the device).The smart notifications detecting people at the door and recordings you can watch from anywhere and the autolock, state update and temporal passwords are already worth the price.On my first review, I was distressed that it required calling customer support to get the round faceplate to install on the door and that the customer support was not easy to reach. However customer support did reach out and did all they could to help me get the round faceplates quickly. Kudos to the eufy team!I encourage eufy to improve the product and communication in a number ow ways to make it even more awesome:Have better information on keys being able to be duplicated if needed, nothing to fear as every other similar lock out there will let you do that and this is an asset that could turn customers away fearing only 2 keys are included. Also, try to include all the right hardware in the box to avoid the issue of extra calls. Finally better support training to resolve and escalate things quickly.Overall, a great impressive product and team and I look forward to keeping using this device and learning more about the ways Eufy innovates in this space.

Great lock overall, especially if you have a good use case for all its features.
I was very excited about this lock and it mostly lives up to expectations. It does what its advertised to do and it does it well. Once you know where to place your palm, it’s easy to always get it right the first time and have the door unlock quickly. The palm vein unlock method itself is very cool and will make you feel like you’re living in the future and should be a fun thing to show off to others at first too.The camera also does a good job for those who want a 2 in 1 combo or don’t want to replace their old dumb doorbell. I won’t be using the video doorbell feature for monitoring because I already have a video doorbell though. But I still wanted it because my parents stay with me sometimes and I don’t have windows near the front door or a peep hole so the screen on the inside is a very useful feature for them so they can see who is at the door without having to open it. So for anybody in my position with elderly or kids, I think the version with the screen can be very useful to have.As for my dislikes. Two things stick out to me. First is that the lock motor is slow. Some new locks have much faster motors to turn the deadbolt nowadays. The Eufy on the other hand still uses a very slow one. Not a big deal, but it’s a minor annoyance because I would like to see progress. The other is that the lock won’t give you an option to turn on the interior screen automatically whether it senses motion or someone rings the doorbell. I know this was probably done intentionally to save battery. But they should give us to the option to have the screen turn on with one method or another so we can already see who is there when we approach the door.Other than that I am a Home Assistant user and integrated this lock into HA using Matter over WiFi. Only the lock and battery is exposed. You won’t be able to expose the camera stream over Matter though. But for those that use Google Home or Alexa, the live stream is available. Control is fast(around ~1.5 seconds) but won’t feel instant. That’s just a minor nitpick on my part since I want everything to be as fast as turning on and off a light lol. I’ve had no issues like random disconnects so far. But it has only been a day so we’ll see. Same goes for the battery life. No idea again since it has only been a day.All that being said I think it’s still deserving of a perfect score because the main features of this lock are executed pretty well. I have a few nitpicks with it but I don’t think it should be knocked down because of that. Compared to what is available right now, it’s pretty much one of a kind with all that it has to offer. Just be sure that you want all these features because there are definitely cheaper options out there if you only want a palm lock or a lock/video doorbell combo. But for those that want it all, I think this is our only option and I can at least say that it does it well.

This is a great lock. Easy to install and set up. It seems to work very well. Recognizes our family palms and not others that I’ve tested with.I like the auto lock after a certain amount of time and you can define a time frame to do this so throughout the day you are not constantly unlocking the door.It only uses the key it came with. Would be nice if it can be rekeyed to match the other house doors. I have not tried to get spare keys made yet so not sure that is an option.The button that covers the key hole and emergency power plug keeps falling open. This is also the doorbell button so it tends to be used regularly and just does not fit tight after you open it. DON’T OPEN IT IF YOU DONT HAVE TO! LOL

I had a lot of high hopes and our family was very excited for this palm scanner. Instead, it turned into a full day of frustration, research and chats with support because after the installation process, it failed at the very first step of Calibrating. We’ve tried every possible solution in existence and nothing worked. It’s essentially a paperweight if you can’t get it to calibrate. During our search we found that it is indeed a common issue with these devices, specifically among the Eufy brand of smart locks. We have decided to return this defective and poorly thought out smart lock and will opt for a brand we used previously without issues. Disappointing.
