Customer Ratings & Reviews

It is very easy to installed and set up and connect to wi-fi. Downloaded the app and control the FamiLock from my phone.

Very responsive the only bad thing for now it deleted our prints

Eufy FamiLock S3 Max is a 3-in-1 smart lock that features a video doorbell and palm scanner. This smart lock unlocks by scanning your palm veins. Eufy claims this technology works for anyone irrespective of their age or physical condition unlike a fingerprint scanner. The setup was easy, and the included quick start guide helps you with step-by-step instructions. The palm reader was easy to register too, and much better than the fingerprint capture. If you already have an Eufy lock, then the deadbolt works with this module. The package includes the interior and exterior smart lock module, assembly hardware, charging cable and the setup guide. The doorbell camera on the front of the module is a 2K HD camera that captures the entire picture with full angle viewing and clarity. The interior of the smart lock module has a 4-inch 1080p video screen that acts as a peephole with clear live footage. You can also use the Eufy app for live video intercom feature. This app also lets you customize additional settings like access codes, video captures, alerts, tracking areas, etc. The best part is there are no monthly fees to use any of these features. The smart lock is operated by the included 15,000 mAH rechargeable battery. A full charge of the battery is rated to last up to 5 months with full functionality. It takes 6 to 8 hours for the battery to be fully charged, and it needs to be taken out from the lock for recharging. But Eufy has included 4 AAA batteries as a backup, so the lock works even when you are charging the battery or during power outages. They provide up to a month of essential functionality. The only downside is the camera functions and palm scanner are disabled to save the AAA battery. In case of emergency, there is a physical key and USB C power interface on the front of the module behind the doorbell button. The video recordings are stored locally on the 16 GB included storage. I wish it was expandable. You can access these recordings via the Eufy app. If you are invested in the Eufy ecosystem, this smart lock is also compatible with HomeBase 3. This will also increase the local storage for the video recordings. The S3 Max seamlessly integrates with Apple Home, Google Home, Alexa, and SmartThings via Matter compatibility. Other features include auto locking when the door is closed, Wi-Fi 6 connectivity, all weather IP65 rating, ANSI/BHMA Grade 1 certification, EMP resistance. One thing to keep in mind, if you have a storm door for your entrance, this might not be the right smart lock for you as the storm door will probably block the camera. Overall, this is the latest all-in-one smart lock from Eufy that is solid and provides all the smart features without any subscription.

great product couldn’t ask for more. my family loves it they so use friendly

I've gone through a lot of smart locks and this one is a winner. Only thing missing is AppleKey. With my doorbell off to one side this lock with a camera and doorbell work perfect for my needs with the camera point right down the approach to my front door.

Love it, is the best brand to buy security items for your house

Great product so far, easy to setup, love the features and the palm recognition is really nice and accurate, I tried different people just to see if it actually works and it does.

palm reader doesnt work very well when you push the buttons it leaves marks

Its an good pruduct definatly feels new on development. but palm reader works good one thing is it doesn't work with home assistant yet so that is annoying eufy needs to get it up and running

I really wanted to love this lock—it’s convenient and works well overall. Unfortunately, it has one major drawback. Once installed, the interior door knob was so easy to turn that my dog, who had never opened a door before, was able to open it and run outside few times. I ended up having to return it for this reason.

This product is perfect for AirBnB. I can monitor who comes in and out, change passcode and best of all is the palm reading to gain access.

It's a cool product with a cool concept that does work but it takes to long. Needs updates to be ready for deployment

Battery barely lasts for a couple of weeks. Purchased it first time and it stopped working after a month use. I returned it and got anothsr one. Seeing the battery issue after a couple of months.

It's very technological, and the fingerprint unlocking is very effective. But the camera quality is a bit poor

Great product, seamless palm readability with a convenient key hole.

Feel like its not worth for the money. Old version works better. Unlocking from outside works Slow most of the time.

doesn’t pick up people walking from right to left in front of the camera or if they’re lingering on the side

I’ve owned a bunch of Eufy products from security cameras to doorbells to locks. The quality and innovation of Eufy smart products is second to none. I loved my fingerprint reading smart lock. I actually haven’t carried house keys in years. I have a Eufy lock on each exterior door on my house. When I heard about the Eufy FamiLock S3 Max with Palm Scanner I really wanted to get one. In the box you’ll find the inside panel, outside panel, battery, AAA batteries, a box of hardware, a Eufy security sticker, and a quickstart guide. My first impression was that the S3 was a solid piece of hardware and the battery is huge in comparison to my old lock. The battery is a 15,000mAH rechargeable battery which last 6 months on a charge. The quickstart guide directs you to get the app for setup and to a video for installation instructions. Having setup other Eufy locks previously I knew what I was doing but I used the step by step video anyway. I did find the video instructions somewhat annoying since you have to pause and start the video repeatedly to perform each step. I think a step by step instruction method like that used on other Eufy products would have been less frustrating. Installation was however a breeze. If you are upgrading from another Eufy lock the S3 slipped right in place using the prior locks door hardware and deadbolt so you can skip those steps just like I did. Basically you install the outside panel and run the cables through the door and connect to the inside panel. Secure the inside panel with screws and insert the battery and the backup AAA batteries and then your ready for setup within the Eufy app. The app setup was also a breeze. You simply select add device and follow the step by step instructions. Once added and connected to wifi you are prompted to add your palm. This was surprisingly a nearly instantaneous process. I added one hand and later added the other within the app after setup. I did sync the S3 Max with my HomeBase 3 for added storage and additional AI features and security. Once setup was complete there was a prompt to install a firmware update. This takes a few minutes and then you’re up and running. Of course my first inclination was to test the palm scanning unlocking capabilities. Wow, very impressive! Just hold up your open hand to the scanner and the door unlocks immediately. Make sure you add both hands so in the event that you’re carrying something you just use the opposite hand. Don’t forget the S3 isn’t just a lock. It performs triple duty as also a doorbell and as a 2K HD camera as well so it has you covered. The FamiLock S3 Max also has a screen on the inside panel which with the touch of a button shows you the view outside your door. I think this a great feature as a peephole function which allows you to see who is at the door prior to opening it or having to use the app to do the same. This is very convenient and a great added security feature. If you’ve never had a video doorbell you’ll love the ability to check your cam remotely and the motion notifications are fantastic for added security or just to know when the mailman comes or a package is delivered. If porch pirates are an issue in your area then the cam is a great deterrent too. They say the FamiLock S3 Max recognizes the unique vein pattern on your hand's palm in just .1 seconds with up to 99.99999% accuracy. From my experience so far this appears to be true. I’ve never had the door not recognize my palm scan and it activates instantly. This is definitely an improvement over my fingerprint reading smart lock which would often fail to read my fingerprint particularly if my hands were dirty or wet. The palm vein reading technology is not affected by dirty or wet hands or even skin conditions. The FamiLock S3 Max is a great product. Highly recommended.

I am writing this review for the eufy FamiLock S3 Max Deadbolt. The S3 Max Deadbolt comes with a built-in 2K video doorbell and palm scanner. This is one of the easiest reviews I have ever written. Why? Because this is absolutely one of the best, if not THE best product of its kind on the market, hands down. When I got home and picked up the package, I thought for sure I had received the wrong product. I mean, it was much heavier than I had imagined. So, I put everything else aside and opened up the box. To my surprise, it actually was the eufy S3. I was impressed by how well packaged the S3 came. The quality of the materials, the intuitive packaging…top notch all the way. As I familiarized myself with the contents, I noticed that the only instructions came in the form of a little folded Quick Start Guide. I looked it over and noticed there was a QR code to scan to access an online tutorial, and a rather short one at that. It all seemed so easy and simple. So I watched it a second time and felt confident enough to give it a shot. I was not prepared for the unbelievably easy and simple installation of the eufy S3! In a matter of about 10 minutes I had it completely installed. Not only installed, but ready to go, save for a few minutes connecting to wi-fi and setting up my eufy account. I don’t know that I have ever had such a non-stressful setup before. It was amazing! 10 minutes. As I was installing each component, I kept noticing just how well-built the S3 is. The materials, the design, the build…from top to bottom the S3 is pure quality. This is not some mass-produced-as-cheaply-as-possible piece of junk, this is a top-tier level product. And I became aware of why the box was so heavy when I picked it up. You won’t find even a trace of cheap plastic on the S3. I mean, everything about it is incredible. Back to the setup, I don’t know if I am just one of the fortunate, but my deadbolt hole was perfectly suited for the eufy right out of the box. The setup required no technical skills, no “bunch of tools,” and everything is designed to assemble without stress of any kind. Their research and development team really deserve a ton of kudos for making the installation fail-proof. Everything just went together so easily. The only tool I needed was a Phillips-head screwdriver. After installing, there is the usual connect-to-wi-fi, setting up an account, etc. And once that is all done, the eufy is ready to use. I wasn’t sure about the palm-scanner feature. To me it seemed a bit too good to be true, if you know what I mean. And way too futuristic. I honestly didn’t think it was going to perform well. I was wrong. To open the deadbolt, all you have to do is hold your palm a few inches away and almost immediately it unlocks. So to prove it’s trustworthiness, I had everyone try to open it with their palm. Worked perfectly. There is a very minor “learning curve” involved, as I needed to learn how to hold my palm so that the scanner could read it. The video doorbell feature is just as wonderful. Anytime someone rings the doorbell, I am immediately notified via the app notifications. Even if they just walk up on the porch. And this is where eufy deserves the most praise… they don’t require a subscription for the doorbell to send alerts and store photos! It’s free. The photos are high definition, and there is no trying to guess what you are seeing. The photos really are clear. Everything about the eufy FamiLock S3 Max Deadbolt/Video Doorbell is amazing. From the super high-resolution photos to the no-subscription-required to the top-notch palm scanner, this is top level! If you are really wanting to invest in an electronic deadbolt system with a video doorbell, please do yourself a favor and get the eufy FamiLock S3 Max Deadbolt!

The Eufy FamiLock S3 is a fantastic all in one device that offers a smart doorlock, doorbell and 2K video camera. Installation is super simple. If you’ve already installed smart door locks before, nothing is different here, it literally takes about 5 minutes to install. If you’ve never installed smart door locks before, no worries. Eufy gives complete and detailed instructions and even offers videos that guide you step by step. With no prior experience, you can DIY this in about 15 minutes. I love the dual power supply offered here. You get both a rechargeable battery and AA battery backup. So even if the main battery goes dead, you’re not locked out and have access to the smart lock and doorbell, however the video functions will be limited until full power is regained. But this is a nice touch of power redundancy. A first for any smart lock I’ve used. The construction is nice and solid, the fit and finish is great and the matte black color will work with just about any décor. The palm vein reader is a first for me and I was super excited to try it out. I will say two things about it: - Yes it does work incredibly well and very fast when the angle of your palm is correct. It locks or unlocks almost instantly - When your palm is not at the correct angle, it can be frustrating For me, I never seem to have any issues with the palm vein scanning. I must have a knack for placing my palm at the correct distance and angle for the lock to scan and unlock instantly. My kids and wife however, don’t have the same luck as me. They only get in with palm access about 50% of the time, usually having to default to their pin code or Apple Home to unlock it. I’ve done it with them as well, and for whatever reason, they just don’t have the same success. They feel that going back to a finger print reader is better, as that worked almost 100% for them. So while I love this lock and it works all the time for me, I wanted to mention that experience for others in my family as an FYI. The video doorbell feature is also very nice and makes this a great all in one unit for those who don’t have video doorbells, outside front cameras or smart locks. This FamiLock is the solution for all of that. The video is crystal clear compare to other similar products in this space, thanks to the 2K sensor on board. The notifications arrive instantly and you can set all the custom bells and whistles in terms of people or package alerts, loitering alerts which is a first for me and pretty cool. You can set the sensor range and define the area in which you want to be notified of motion or activity and the FamiLock even has a built in screen on the back of the lock where with a push of button on the lock itself, you can see real time what the camera sees. Great for when you don’t have your phone and need to see outside without opening the door. Eufy gives so much custom setting controls for everything regarding the lock and autolock, the video settings the notifications, etc. and what’s also great is that the video is stored locally, not in the cloud. This is a great all in one solution for front door security with leading edge technology and customization that makes Eufy products some of my favorite.
