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.

I’m really happy with this Eufy smart lock (E31). Installation was way easier than I thought it would be. Everything fit right into place with my existing deadbolt. The black finish looks nice and modern against my door. I did notice my handle is still silver, so I’ll swap that out soon to match. But as far as the lock itself, it works perfectly. I use the fingerprint reader most of the time and it’s quick and reliable. The app was simple to connect and I like being able to unlock from my phone when I’m heading home and my guests are already at the door. Overall, definitely worth it if you’re looking for a keyless lock that’s easy to install and looks good. Very happy with this buy!

Works as intended. Love that it is rechargeable. You can manage access and give everyone a different pin or set a temporary one. You can set notifications when it unlocks or locks.

The Effy deadbolt is a great convenance! It gives me the ability to program different codes for different people I want to have access to my house. It also lets me lock and unlock the door remotely. Don't forget to charge the battery!

This product requires a hub for matter connectivity with matter enabled applications and product description does not say that. I would say it's not clearly labeled like that.

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.

There are multiple things to like about this replacement lock; installation took about 15 minutes, setup 5 min tops, integration with Apple Home zero problems. Set up finger print entry for my wife and I and she said she has had zero issues using her print. Also, I have multiple locks. Once my print was set up for one lock, it worked on the other two locks. Would definitely recommend.

This product is great. Easy to operate. Works effectively. A great solution to always having to carry a key or run up and down the steps to let someone in.

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.

easy to set up and works great. i would recomend this product.

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.

I replaced another smart lock with this one. Mainly because of the fingerprint feature. I will say if it is cold out side, your fingertips will be dry and it sometimes needs to be caressed but this is a great unit. The history and key bypass is great too. My last lock was blue tooth but Wi-Fi required additional hardware. This unit has it all. I make it automatically lock the door if left unlocked and I have a history of everyone that has entered. Plus coupled with my ring video (it doesn’t connect to ring, I just use together) I have pretty good idea of who comes and goes. I have parents living with me and my grown up son and friends have access so our house is a hub sometimes. Anyway, thanks for a great lock.

This lock has worked excellently and much better than the more expensive Yale lock that I returned. Fingerprint recognition is really fast and consistent. I like that the battery lasts a long time and is rechargagle.

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!

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.

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.

The difference between the E31 and the E30 is the fact that it has a rechargeable battery. But man, does it come in clutch. The rechargeable battery is a blue brick that can be recharged with a USB-C cable. I keep hearing that the E30 keeps getting blasted with negative reviews on the battery life, but this thing is rechargeable! Comes with ease of life features like code scrambling, a nice finger print sensor, and the ability to use it with your virtual assistant(s), such as Alexa or Apple Home/Siri. This does drain the heck outta your battery, but guess what? It's rechargeable! Only complaint is that it's not tactile and is a bit hard to see in the dark. But it keeps getting discounted and the pricing is really really nice.

Pros: Easy setup with clear instructions. Fingerprint unlock works well. Worth for the money.

Easy install, easy use. Love the touch id feature.

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