If you're in the market for an extra-secure lock that you can open remotely, buy this one. Ease of setup: I have zero experience with home improvement type things - I’m normally a task-rabbit girlie. But I’m currently a bit poor, so had to suck it up and install it myself, and it truly was simple to do. If I can do it, any idiot can do it. Quality: It's good. I feel like you can't go wrong with a Eufy product. They may be a bit pricier than others, but they're always good quality. They look nice, feel nice, act nice, etc. Functionality: It works. One little plus is that it works even if the batteries are dead. I was out of town and needed someone to stop by my house. The app told me that the batteries had died and I was afraid the lock would stop working and they wouldn't be able to get in. I was pleasantly surprised that that was NOT the case! One (pretty obvious) thing to note: if you have a door that kind of sticks, make sure you shut it hard / all the way. This can't lock if the deadbolt isn’t lined up with the hole in the other side of the door. App: This can be controlled remotely from the app because the lock connects to wifi. I have another Eufy lock (one of the fancier ones with the fingerprint thing - which this one does NOT have) on my front door, and that one can only be unlocked with the app if you're close enough to it on bluetooth. Which is honestly so dumb, because if I was at home when I needed to open the door I'd just walk over and unlock it manually. This one however, is a major upgrade because I can unlock it from wherever I am! Game changing for if you need to let someone in while you're not home, but you don't want to give them your code. Just unlock it for them and then re-lock it when they leave!

This eufy C30 lock was extremely easy to install and setup using the APP. It easily connected to BLUETOOTH and WiFi without fuss or problems. The Built-in WiFi is what prompted me to try this lock. It is very good. Anyone who is looking for a reasonably priced, no-gimmicks, easy to setup and use, keyless lock should consider this one - the eufy C30. The APP was very easy to setup, understand it's functions and to use it to provide multiple access codes. I also had extremely good experience with their Customer Support. I had to move my lock from a RIGHT opening door to a LEFT opening door. I contacted Customer Support to ask how to reset the lock for the change in LOCK DIRECTION. The support assistant was extremely courteous & knowledgeable; provided the FIX over the phone, as well as by email, with a problem ticket number, in case I needed a follow-up call. I had no trouble at all following their instructions and the LOCK (eufy C30) and it's APP are working perfectly in it's new location. This lock provides what I need, from an easy-to-use keyless device. It is now installed on the side door of my garage.

I installed these smart locks on the doors of several of my rental properties as the guests frequently complained about using the touch screen interface on my other Eufy smart locks. For a bare bones and extremely cheap smart lock, these are the absolute best smart locks I have ever used except that they require 4AA batteries and they chew up battery life incredibly quickly. I originally used Amazon branded batteries and they died within the first week of using the smart lock. I next tried Duracell Extreme batteries in one lock and Energizer's "longest lasting" batteries in another... Both experienced complete battery failure in under 6 weeks. The Duracell batteries were completely dead and the lock did not give a noticable warning (neither on the lock itself nor in the mobile app) to warn me of the imminent failure. The lock completely failed to operate even without the remote functions... Luckily I had the physical key in a lock box and I could enter the home through the garage as an other backup... If you purchase this lock, plan on changing batteries every 3-4 weeks, and please set up alternative ways of entering the home, especially for a rental property... At least the digital keypad Eufy locks allow for keypad operation even after the mobile/remote futures go off line. The digital face/keypad is extremely difficult to use, but the finger print reader works amazingly well as does the mobile/remote features.. With the digital Eufy lock, you get a rechargeable battery pack which gives off an extremely loud warning notice when the battery pack needs recharging, and which gives a great notice through the mobile app. With this lock chewing up batteries so quickly (without using a rechargeable battery pack) it is absolutely useless for my needs and I have already swapped these out for the older Kwikset smart locks without remote app ability as batteries last well over 12 months on those. I keep one entry way with a remote opening smart lock while keeping an older generation smart lock on the front door), as a means to ensure the best access for my tenants. I wanted to love this lock, but battery life is so bad, that I can't use it.. Everything else about the lock is absolutely amazing.

This does not have the fingerprint recognition but it’s exactly what I wanted. Keys are quiet and work Every time. I had no problem adding it to my Eufy systems and automatically hooked up to Alexa. You can turn off the beeping. The lock appears sleek, sturdy and durable. Can use a key, codes or the Eufy app to open/close the lock.

I love everything about this lock, except for the battery life. Easy to use, has a key as a back up, easy to install, but it eats through AA batteries SO quickly.

I use eufy security on my property and I am very pleased with their products, so when I needed to change locks, I upgraded to these digital locks. As I have pets and I work odd schedules, my sons have to have keys to the house to feed and check on pets. This way each has their own code and I know who and when someone comes and goes. Also with the eufy app I can lock and unlock remotely, change and add who has access, and at a glance I can see if I remembered to lock the door when I left. Very easy install and sync with app and it works with Alexa. These require 4 AA batteries and seem to last a long while before needing changed, depending on which has the most use. Note: I bought rechargeable batteries just for this, that way I always have a set ready for when they need changing. The eufy app does give you a heads up when a locks battery is getting low. Good product.

I had a pretty bad allergic reaction that made me stay in the hospital for a few hours and no one had the keys to my apartment to keep an eye on my dogs. Decided to get this just in case I had another incident of the sort. Ordered it from Amazon and it never arrived but I ended up getting it in person and it has been the best purchase I've ever made. The set up was easy, the lock functions well and it looks fancy. Only downside that it has is that it doesn't have battery included. However, I bought the rechargeable batteries and the battery last for almost 3 weeks. Im 27, live by myself, and I was able to install it without help.

This is a mixed bag. I've had 2 of these for a little over a month now. One on the front door and one on the back door. Ironically, the back door sees more use and traffic than the front door. That said, the front door has already killed a set of batteries. I used a set when I first installed it and it was dead within 2 days. Thinking maybe I used not so fresh batteries, I installed another fresh set. We are not even at 6 weeks and those are dead. The back door still shows its at full battery life. So one works great and the other does not I guess. So take the reviews with a grain of salt on battery life because so far my results are 50/50. Other than that, Installation is easy if you have installed a door lock or two. Setup in app takes a second but works. Interface is pretty simple and straight forward, set up wifi. Firmware updates. Set up a few pass codes. And set your auto lock feature, etc. Overall im pleased with their quality. I wish there was a more straight forward answer on how to re-key them so I can get all my locks to match a set of keys. That hasn't been figured out yet, but I also havent had the time to look into it. But next I will be looking into replacing the battery hog.
