Love the fit and finish, the app, the functionality

Reviewed in the United States on June 28, 2025

Style: DeadboltColor: NickelVerified Purchase

I’ve been using this Eufy smart door lock for a few weeks now, and I’m genuinely impressed. From the moment I took it out of the box, the quality stood out. The finish looks sleek and modern, it adds a really clean, premium look to the door. It feels solid and well-built, not cheap or flimsy like some other smart locks out there.

Installation was straightforward. The instructions were clear, and the whole process took less than 30 minutes with just a screwdriver. I didn’t run into any surprises, which I appreciated.

The fingerprint sensor is one of the standout features. It’s fast and accurate. I’ve tested it dozens of times and it unlocks almost instantly with just a light touch. No lag, no failed attempts. It just works, even when my hands are a little sweaty or damp.

Battery life so far has been excellent. I haven’t needed to charge it yet, and the app still shows a strong battery level after regular daily use. I also love the app. It’s clean, easy to navigate, and packed with features. I can add or remove users, see a full lock history, and get notifications instantly when someone unlocks the door. Remote access works flawlessly too.

Overall, this lock checks every box: great design, long battery life, smooth installation, fast and reliable fingerprint recognition, and a fantastic app experience. If you’re looking to upgrade to a smart lock, this one is absolutely worth it.

This one came a few hours later (same day) and I installed it myself in 15 minutes, just like the manufacture promised. I pulled up a youtube video and it went exactly as it was supposed to.
The app functions well and was simple to install and pair. What a nice sound, hearing the deadbolt latch on demand from another room.
Highly recommend.

The Eufy C220 Door Lock has been a game changer for my home! Installation was straightforward, and the instructions were clear. I love the sleek, modern design—it looks great on my door. The smart lock works flawlessly with the app, and the fingerprint recognition is quick and accurate every time. I especially appreciate the convenience of unlocking the door remotely and knowing exactly when it’s been used. The battery life is impressive, and I feel much more secure with it in place. Highly recommend this lock for anyone wanting both style and security in one device!

Great lock overall!

Reviewed in the United States on July 25, 2025

Style: DeadboltColor: BlackVerified Purchase

I have had this lock since December of last year. Currently in July, it is still working without having changed batteries or having any problems at any point during its time on my door. It is made out of metal which makes it feel durable and well made, and the finger print sensor works well as long as your finger isn’t wet. The phone integration is incredibly useful, as I can ensure my door is locked from anywhere and make schedules for ease of mind. It was also no more difficult to set up than a normal lock and gave no problems connecting to my phone. It is also extremely nice to have the ability to use a key in the event that the technology stops working. The only problems I have with this product are the fact that it gets very hot if the sun is hitting it (although this doesn’t impact its performance) and the touch screen has no physical impressions of the numbers so you need to see them to hit them correctly. Overall, this product is a great value and I would recommend it to anyone looking for a cheaper smart lock.

Works great and no more Smart hub needed !

Reviewed in the United States on April 27, 2024

Style: DeadboltColor: BlackVerified Purchase

I've owned the C220 lock for a month and have found it to work really well. It took about 10 minutes to install and no modifications to my door were needed. The lock is well constructed and is heavy. The management app is well done and easy to navigate.

Things to note:
1. Some older people can have hard to read fingerprints. This is not specific to Eufy. Use a code number for them instead if this is a problem.
2. The battery life on my lock has been great as my wifi is close by. The further away the lock is from your WIFI access point, the more demand there is on the batteries. This is why some people report great battery life while others complain it's terrible. I believe it took 8 batteries.. it should last a long time.
3. No more smart hub!! Good riddance. Adding and removing codes or fingerprints is FINALLY easy! This might be the biggest difference.
4. The touch keypad CAN be seen in direct sunlight
5. I did not try the geofencing but it has the capability, provided everyone in the family has the app on their phone. It could auto-lock and auto unlock if configured to do so.
6. I did not test doorbell or camera integration – but it has that feature.

Gripes: These are small but need to be noted
1. For renters: temporary/scheduled access codes work fine but there is no integration with text messaging (or email) to create the code and send it in a single process. Heck, the app is already managed on your mobile – why not do this? Now I have to separately send a text with all the details when this could have been easier.
2. When using a number codes, you have to press the keypad once to wake it up, enter the code, and then press the enter key on the bottom right of the panel. Why do I need to press enter? Why not open the lock after a second if no additional keys are pressed and the code is correct? Now you have to tell potential renters of this requirement to press the enter key. My point is: the enter key is not be obvious to people unfamiliar with the lock.
3. On the app, the battery life is shown as a tiny battery picture with lines filled in for battery life remaining. Would it have killed them to put a percentage number next to it?

Overall, this is the best lock that I have tried and I have tried about 6 others to date. I hope you found this review useful.

quality, functionality, & app are all good

Reviewed in the United Kingdom on March 3, 2025

Style: DeadboltColor: BlackVerified Purchase

I took out a faulty Yale deadlock on my wooden apartment front door, and having checked the measurements carefully with the instructions (before ordering!), I found it very easy to install. It took a couple of hours, but mainly because my old door has had a couple of previous locks. I do have a lot of tools available, and in my case needed chisels, drill, screwdrivers & some filler …. but in a new door, this should be a dream to fit.
I am really impressed with how it works, too. I don't need a separate control hub for this model, as it works through WiFi & is powered by battery.
The eufy security app is *very good*, and this made the difference for me, against a similar offering from a very well known company (named above).
So, I can open the door with codes, my fingerprints (as many fingers as I want to add) and I can allow others to do so too. I can set different levels of privilege, and use timed and temporary entry codes, all from my phone. I get an (optional) alert every time the door is opened or locked.
I have ADHD, and eufy security gave me back my confidence – I set the door to lock automatically after a certain period of time, so I never forget to lock up!
I can easily add a camera to my door lock – I haven't as it is an internal apartment door – but
I do have a eufy outdoor camera, which stores videos locally on my phone. This means I don't need to pay for any storage subscriptions with my security system.
All in all, I'm very happy with my eufy tech!

Best Smart Lock! And great customer service!

Reviewed in Canada on July 24, 2024

Style: DeadboltColor: NickelVerified Purchase

It has been a month or so since I purchased this lock. I wanted to test it for some time before writing a review. And now a month later, I can say definitively that this is the best smart lock in the market.

It simply just works.

Once I installed the lock, it paired with the eufy app seamlessly. The features I looked for where all found in this lock:

1. Lock must be smart (ie. connects to the wifi to allow me to control it remotely and get status if it’s locked or not at night). Being smart, it means I can generate one time codes to let people in remotely over the wifi. This convenience you wont have with a non-smart lock or Bluetooth connected locks. As those require you to be next to the lock to make modifications like add a new entry code or allow someone in.
2. Fingerprint entry. This is a game changer in terms of convenience. You want the fingerprint feature as it will save you a ton of time. You don’t have to manually enter digits one at a time. It’s a must have time saver.
3. Key pad. In case I want to let a guest in, they can enter using the keypad. I can generate a one time code ahead of time and send it to them via messaging.
4. Back up USB power port: In the rare case your batteries run out, this convenient power allows you to power the lock with a USB power bank and let you in the house. Then you can replace the batteries.
5. Battery powered: it uses 8xAA batteries, which seems a lot at first, but it means it will last long. It has been 1 month now and the lock is working very well. Using removable batteries makes this product more affordable, which is a huge plus.
6. It looks good!
7. Customer service has been really kind to me.

The above 7 reasons make this lock an unbeatable lock. Yes, it doesn’t have a camera and it doesn’t have a door bell feature, but I already have a doorbell camera in my front door. I use this smart lock in my back door.

A note on customer service:
Customer service is very good. After I purchased the smart door lock and then after opening it, I realized that my door had an old style drive-in plate instead of the modern square plate. The instructions that came with the product said to contact customer service. My initial thought was that customer service would have a really difficult time to solve my problem. But to my surprised, they were very helpful. There was a little confusion in the beginning, but when they figured out what I was missing, they went above and beyond to help me locate the necessary part and then placed an order for me. This showed me that they really care. I have trust in the brand and the products and now recommend to friends and family!

If you are having some doubts or haven’t quite decided on which smart lock you want to use in your home, this is that lock. Get it. You will love it. If you have money and need some more features like video camera, eufy’s got you. Trust me, just get it, you won’t regret. Enjoy the convenience of a modern smart lock for your home, family, and friends.

Have been using this for about 6 months now and it has been excellent. No issues with the fingerprint reader for me – it works as well as the one on my phone, I have yet to need to use the included keys, which is the main reason why I purchased this. Battery is still more than half full so that hasn't been an issue for me either. It was very easy to install and came with everything you would need. All around a solid product!

Waste of $ and batteries

Reviewed in Canada on April 1, 2025

Style: DeadboltColor: BlackVerified Purchase

Unless you want to be replacing batteries every 2-4 weeks avoid this product! We made the switch after loving our doorbell and floodlight by Eufy, and wanting to only have one app for our smart home products, but the locks are terrible. We previously owned a Yale smart lock and maybe had to replace the batteries semi-annually if not longer. SO disappointed! The fingerprint function also only works <50% of the time – save you money on this function. We’ve reached out to Eufy for support, awaiting a reply but suspect we are out our $ and will need to replace with another brand.
