The eufy Security Smart Lock FamiLock S3 Max was very easy to install, and I really like the smart technology built into this lock. I absolutely love the screen and the motion recording feature, it adds an extra level of convenience and security. The palm identification feature is extremely useful and works great. I haven’t tried the code access feature yet, but so far, my overall experience has been excellent. Definitely a great smart lock, and I highly recommend it!

he eufy Security Smart Lock FamiLock S3 Max is an excellent upgrade for home security and convenience. The palm vein recognition works quickly and accurately, making it easy to unlock the door without carrying keys or using a phone.nstallation was straightforward, and the lock feels solid and well-built. I love the added security features and the convenience of being able to manage access easily. This is a great choice for anyone looking for a secure, high-tech smart lock with excellent connectivity.

So far we love this lock! The physical installation was pretty easy. We had some issues connecting to the app. The issue was that we had to connect to the 2.4ghz wireless, which isn't unusual for devices. Then it wouldn't connect to Bluetooth. I pulled the battery out for about a minute and that resolved that issue. Overall, really great. The app has worked wonderfully so far and I am Soooo happy to not have to pay a monthly fee.

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.

I am a big eufy user. I own several eufy products: the cameras, the doorbell, the motion sensor, and the HomeBase 3. I expected the Familock would integrate flawlessly, just like my existing devices. I read the negative reviews, but I assumed those customers received defective units. That assumption turned out to be a major mistake. Installation Was Easy, Operation Is Not Actually putting the lock on the door was easy. The instructions were good, and it went on just fine. The real headache started the minute I connected it to the HomeBase. Literally the next day, the lock just disappeared, it was offline in the app. I thought maybe my whole HomeBase died, but nope! Every other product, the doorbell right next to the lock, the cameras, was working perfectly. I had to close the app and reopen it three times before the lock decided to come back online. I hoped it was just a fluke, but I was wrong. This happens all the time now. The connection is totally unstable, and I constantly have to mess with the app just to see if my door is locked. The Missing Matter/HomeKit Feature Another huge issue is the advertised compatibility. The product description clearly states it supports Matter and Apple Home connectivity. This is misleading. I have repeatedly attempted to connect it to HomeKit, and the app constantly returns an error message: "the camera cannot connect to matter at this moment." The promised integration is completely unavailable. The Failure of Remote Access (And Value) The entire point of buying a Wi-Fi connected smart lock is to have reliable remote access—to check the status or unlock the door when you are away from home. Because this lock constantly drops its connection, that functionality is nonexistent. I cannot rely on this device when I need it most. Instead of getting a modern, convenient smart lock, I feel like I paid a huge sum of money for a completely unreliable product that barely functions better than a basic In summary: The setup was easy, but the lock constantly drops its connection, making remote access impossible, and the Matter/Apple Home feature is falsely advertised. This product simply does not deliver the basic features expected of a smart lock. Save your money and look somewhere else.

Update: I got it November 24 and the faceplate stopped working January 19th. Leaving as usual and couldn't press the button on the keypad to lock, no lights, no sign of camera working, don't thing the interior screen would either. Doorbell did work, as did app access to lock and unlock. No warning. I remember the battery being around 50%, it had been around 45-50 degrees overnight but lock is fairly protected. Removed the battery to charge it, on the AAA's it works a lot like it had been, auto-locks and app can lock/unlock it. except doorbell just says "main battery low" when pressed. Put the main battery back in, and everything works again. Unsure whether it was simply the removal/replacement or it actually needed charging. Neither would be great. Guess we'll see in 2 more months. And the AAA's dropped about a third in the couple hours without the main battery. Otherwise I had just been raving about it, good camera with access to past events without subscription. Palm often works as soon as a put my hand up--but sometimes have to move my hand a bit. Original review: I do like it quite a lot, it's great that it does 3 jobs at once: electronic lock, video doorbell, security camera--and it seems to do them all well. It's pretty fast, seems well built, and it does a great job of knowing when the door is closed to auto lock (many others have janky add-on contact sensors/magnets, pretty sure this uses the camera and local AI instead). Also, it was unclear from reviews I'd watched but this DOES HAVE local storage for recordings (and it lets you download to your phone), so it does NOT need an extra Eufy hub to store the video! There are a couple negatives however: very little adjustment range on installing which left a sliver of the door hole visible on the side of my installation, some kind of extra gasket or a little more adjustment range on the deadbolt alignment would be great; the key is very nonstandard so many report it's hard to get duplicated--however given the backup battery plus externally accessible charge port maybe people should rethink how much they need a key; the range/sensitivity setting for the people detection doesn't do that much in a condo/public courtyard setting--I would love to have something like ability to categorize loitering detection at a higher level of alert than a passerby... and also if it wouldn't report me using the lock as loitering! Overall though it does all three things pretty darn well and I'm glad I bought it, installation was easy, the vein scanning seems to work pretty well and the auto locking feature is great.

I’ve had a couple other battery powered locks. None of those can compare to this one. The palm recognition works great even under rain conditions, unlike the finger locks. It comes with a screen in the back that you can manually turn on with a button, and it also turns on when someone rings the door bell. With the app you get notifications, replays, and can see live. You can two way talk with people at the door. You set up palm and code entries through the same app. You can also delete those at anytime you want through the app without having to reset the device like most.

The eufy security smart lock s3 max is a game changer for our home security and entry door lock. It was extremely easy to set up straight out of the box. Came with all the tools and hardware needed. Looks durable, stylish, and versatile. I can use palm vein recognition which I have never heard of before till using eufy. This system is very accurate and uses biometric data to analyze my palm and open/unlock the front door. Super cool and unique. The other option to be unlock is also using a 4 digit pin that you can easily set up or the old school way if using a key. It is wifi enabled so connecting to the app is seamless once you make a user name and profile. Allows for custom configuration to your liking which is a plus. I.e. loitering alert, AI interface and recognition, and other neat features. If you have the eufy hub like I do, makes it even simpler to store videos and seamlessly connect. The camera is 2k and very crisp and clear. It also allows for getting a live preview of who's outside directly on the backside of the lock which is unique without having to open the door. 2 way communication is built in as well. Awesome set up that is very easy to use. Customize the chimes as well with the integrated door bell. Super easy to spot at night as the keypad lights up and so does the door bell light. Night camera activates and records flawlessly at night as well. All in all, I'm a big fan of all eufy products and this seamlessly integrated to my eufy ecosystem. I can also link it with Alexa and Google which is a plus. It's apple home capable but I have not tried since I don't use the apple ecosystem. No issue on the noise level and most definitely well worth the value.

very easy to setup and it has so far been a great experience using after changing from another devise model

Buy it

It's great. I sucked at installing it but if I had ever fiddled with a doorknob before it would have been easier

Its nice and has all the key features such as the video camera, doorbell & passcode. If you forget to recharge or run out of battery you can use a key to unlock as well.

J'adore je recommande fortement a tout ceux qui veulent la sécurité de leur foyer facile d'installation bonne application bonne qualité d'image et bonne connectivité! La vision de nuit ma surpris !
