Customer Ratings & Reviews

Upgraded to this lock from an August Smart lock. I am really enjoying the convenience of the fingerprint sensor. It claims an 18-month battery life, so we'll see how that goes, but the battery is rechargeable, so there is no real additional cost there. Beats the expensive CR123 cells the august used to burn through every couple of months. The only thing i would like to see in a future model is a more standard key way that can be Rekeyed to match the old deadbolt. With this lock, you have to use the keys that Eufy provides, which is a little thicker and can't be used in my other deadbolts. Overall, I would highly recommend this lock because it works great with both out goofle home and apple homekit set up.

The Eufy E31 Smart Lock is a game-changer for our family. The fingerprint and code access make entry effortless, even for the kids. It’s reliable, easy to set up, and looks sleek on our front door. The app integration adds extra convenience. Peace of mind and security in one device!

Install was very easy. Setup was super easy getting it on the eufy app and connected to Apple Home. I wish all the eufy products would be matter compatible because it works great. The only downside is I had to setup multiple fingerprints and pins through the eufy app. I think thats due to matter being so new and i didnt down the rating for that.

It works great on my door and I love how it works with Apple Home. For the price I think it is a pretty good lock. Though I got it for sale for just over 130, probably wouldnt have done it for its full price. If you can get it on sale it’s totally worth not needing another key on your key chain and being able to give people temporary access.

Love this lock. Quick and responsive fingerprint scanner and love that it is homekit compatible

I have been happy with this lock so far. Install was pretty easy. You might need to drill the hole out more in your door jamb if it does not line up properly. The only issue I have had is when I linked it to my eero mess system it would lose connection about every 2 days. I then linked it directly to the router and had been fine ever since. It can be a little fussy on your finger print for unlocking the door. I found that if you just do 2 setting of your finger print it works fine almost every time now. You can unlock the door from the app and it also tells you who unlocks or locks the door. I think for the cost it’s a nice wifi lock.

Love the lock.. best purchase ever not sure what took me so long to get a key less lock. Now the kids can have entry without keys! Let a spend the night when I was out of town and it work great didn’t have to hid a key outside.

It's nice to come to the door with your hand full of groceries and not to have to reach in your pocket for keys and then find the right one. Just use your finger or punch in your code and the door unlocks. Easy installation, easy to use. It does require a Thread Border Security. Google Nest has it. It has a key backup and a battery that is suppose to last months.

Very easy to install and works well assuming the lock prep is correct

I recently switched from Yale. Used it for 2 years and 2 months. Something kept draining my batteires with Yale every single week. They offered no help and the Matter upgarded was an additional $200! This Eufy has everything you can think of and even a rechargeable USB-C battery! Love it! I will get all Eufy locks for all my external doors!

I was very apprehensive at first. But this has worked out fantastic. It is so much easier to get in the house and to have the auto locking option is perfect for us. Great buy!!!

I’ve had it for a couple of months. Periodically loses connections with Apple Home. Battery life not as much as I thought it would be. Overall, works ok.

Works great. Fingerprint works flawlessly.I also like very much the auto lock feature where i can set a certain amount of time when the door will automatically lock after being unlocked. Works great with alexa. 5 stars. Would definitely buy again. I am going to buy another for the back door.

I love this, it was easy to install and the app is cool to un/lock the door. The codes are easy to set up, even the temp codes. I like the fingerprint too jus make sure you put your finger EXACTLY in same position.

So easy to set up. Like the features the easy add users. 3 way access- thumb, key or key pad. Sleek look and design

I was looking for something updated because my daughter has a bad habit of forgetting to lock the door. This one locks after 1 minute and i feel way better being that i can go right on the app and lock it myself.

I purchased this lock to replace a Yale Assure 2 that does not alert you when the batteries are low. Due to the layout of our house, this is an issue as there is no other way in when the lock isn't functioning. Unfortunately, this lock is also no good. When not installed in the door, the lock cylinder turns smoothly. However, upon inserting it into the door, the lock cylinder freezes up consistently (tested with the door open). One out of every 10 operations is smooth once installed but otherwise it jams up. The lock is not powerful enough to overcome this which results in one being locked out. There is no obvious reason for this behavior other than the slight amount of play in the orientation of the lock cylinder potentially causing the issue. Other eufy locks have reviews that report the same issue so it must be a feature.

Easy to use, sleek design. Definitely looking forward to buying other Eufy products.

Easy install, easy set up. Battery took about 16 hours to charge from about 65% to full. But haven't had to plug it in again yet.

The installation was fine, just need to be carefull that the door closes without pushing or pulling, the barrel fits the wall hole, etc. The device is GREAT.
