    Peace of Mind Every Night with a Rock-Solid Smart Lock
    The build quality and handle design stand out immediately. The lever has a solid heft to it–smooth and comfortable to grasp–and having lever hardware instead of a knob makes a difference when carrying groceries or juggling bags. It feels like a small upgrade that pays off every day.The most important feature for me is the ability to schedule it to lock at a certain time every night. Now I don’t lay in bed wondering if I remembered to lock the door; it just takes care of itself, and that peace of mind is huge. Fingerprint recognition isn’t flawless–it often works on the first try, but sometimes I have to try again–but it’s quick enough and reliable enough that I never think of it as a problem.Installation takes some patience, but the instructions are clear, and the process is very doable if you pay attention step by step. Once installed, the app setup is simple. I think of it as “set it and forget it”–I created the schedule, turned on notifications, and haven’t had to open the app again. Unlocking makes a quiet mechanical sound, and there’s a fairly loud beep by default that can be disabled (I turned it off right away).Durability has been excellent. My unit is fully exposed–no overhang, sitting in direct desert sun and rain for seven months–and it has never faltered. I’ve only had to replace the batteries once in that time, even with multiple entries and exits every day. The Wi-Fi connection has been rock solid as well; remote access has never failed me.I liked this lock so much that I purchased another one for my garage side door. It’s a product that combines comfort, reliability, and peace of mind in a way that makes it easy to recommend.

    Safe, strong, and easy to install and use.
    This is a great lock and normally a very good price on Amazon. Installs easily and setup is quick and intuitive. The fingerprint programming is just like on your iPhone; the reader quickly recognizes your fingerprint at various angles. The integration with the Alexa skill took a little to figure out, but that works fine. The app makes it easy to add users, assign temporary codes, and unlock on demand. Wish there were a one-click button in the app or a keypad code to keep the door unlocked, but instead, you have to disable autolock in the app, which is less intuitive. You can adjust the volume or turn off the entry bell, but I would love to be able to change the tone as well. Also, it would be nice to have any brand of RFID card work and not have to purchase their special one. The unit feels very rugged and secure. Overall a good buy.

    Recommended!
    Nice lockset, very attractive, good app. Fingerprint works great! The unit I was using before this Eufy had a fingerprint scanner that was not as reliable. I also love the fact that it is wifi compatible (my previous lockset required a bridge). I also like the fact that this lockset uses a physical key that is can be duplicated. My previous set used a physical key that had a strange curved profile – certainly effective at preventing lock pickers, just not friendly to folks who need/want more than 3-4 extra keys.

    Good smart lock
    Great lock with great features. It was easy to install and looks slick. My only complain is that it uses AA batteries instead of a rechargeable one. I have to change my batteries quite often in comparison to my other smart devices.

    Don’t buy if don’t have unlimited supply of batteries
    I bought 8 of these for a business in July 2025 based on the reviews. The price was good on prime day but the functionality lacks far behind all other smart locks I have ever used. First of all using wifi as the communication protocol is a dumb idea, it kills battery life. Each lock has 8 AA batteries and last a little over 2 months with fair amount of use. This compares to my Yale zwave lock that uses 4 AAA and I only have to replace them once per year for the same amount of usage.If you’re buying this with the goal to connect it to home automation system like HomeAssist, then don’t! This lock and app has very little functionality and doesn’t connect to any other major systems. It’s very inconvenient trying to manage lockcodes doe 8 locks without a decent system. I wouldn’t not recommend, hard for me to say since I am an eufy fan but this product is a disappointment

    Very happy with this lock
    This lock works well and the app is easy to set up and use. I chose the Eufy E31 for my front door and the C33 for the door between my garage and laundry room because I wanted both to use the same app. The Eufy combination offered me all the functionality I was looking for at a better price than other brands. The fingerprint recognition on the C33 works perfectly because the design of the handle makes your thumb land naturally in the right place every time. Overall I’m pleased with the two locks I bought. Easy to install and set up after getting past step 1 – prepare the door, both of my doors needed holes adjusted before the locks fitted.

    Have used in multiple locations. Great option for doors if want remote access.
    Have used this lock in 2 locations now. Very easy to install and the eufy app guides you through the setup. Thumbprint technology makes it easy to open without having to use the code. Being able to open remotely if needed via WiFi is very helpful.

    Eufy C33 lock rocks!
    I love the Eufy C33 lock, it works awesome! The fingerprint reader is the way to go. I don’t understand the purpose of the privacy lock switch, I would rather use that inside switch to keep the door u locked. I’ll have to play around with it to see if I can keep the door unlocked at times. The only negative thing I have to say about it is the battery cover pops off once and a while when the door gets sucked closed too hard from the garage door being open. Not sure of the cause, but something that was overlooked by Eufy. I put a piece of black electrical tape above the top of the battery cover, hoping the issue will go away.
