    • Looks great, battery strong 6 weeks in.
Color: Nickel Item Shape: Modern Set name: Deadbolt
Love the look and works great. I purchased this lock 6 weeks ago and so far it has been exactly as described. No problem so far with battery life and connectivity has been just fine. The app seems to work really well. It's easy to use. I do think it is a little loud when you use it, but I don't mind that because I like hearing when it's in use. It's also easy to program fingerprints and codes. Overall I really like it. It was easy to install as well. We have had some pretty hard rain recently and I haven't noticed any water intrusion. I also live in a very hot place and it's in direct sun part of the day, and so far that has not been an issue but it hasn't so far. The battery life indicator is still showing that the batteries are doing great. I give it a thumbs up for sure. ... show more

    • Reliable Smart Lock After Months of Daily Use
Color: Black Item Shape: Modern Set name: Deadbolt
I’ve been using this eufy C220 smart lock for months as our everyday front door lock, and overall I’m very satisfied with it. The keyless entry is probably my favorite feature. The fingerprint reader makes it very convenient to get into the house without taking out a key, and using the keypad or app gives us additional ways to unlock and manage the door. After getting used to keyless entry, it’s hard to go back to a traditional lock. The lock is also very easy to use. The app is straightforward, and being able to manage the lock from my phone is especially convenient. I like the appearance as well. It has a clean, modern design and looks good on our front door without looking overly bulky. After months of daily use, it has also given me good peace of mind. Being able to check and manage the lock through the app is reassuring, especially when I’m away from home. The motor makes some sound when locking and unlocking, which is normal for a motorized smart lock, but I haven’t found the noise bothersome during everyday use. Since this is installed on our exterior front door, it has also been exposed to normal changes in weather and temperature. So far, I haven’t had any problems with its outdoor performance. Most importantly, after months of regular use, the fingerprint reader, keypad, Wi-Fi/app features, and locking mechanism have continued to work well. Overall, it has been a convenient and reliable upgrade from a traditional door lock, and I’m very happy with it. ... show more

    • Issue resolved.
Color: Black Item Shape: Modern Set name: Deadbolt
EDIT: Eufy support reached out and they were able to resolve my issues. I was surprised that they helped fix the issue. I would buy from them again because the support was excellent. ORIGINAL: I will start with the positive. The lock was easy to install. It feels pretty solid and having the option to access the house by finger print, the app, keypad, and key is pretty cool. Thank god you have all of those option because you will need them as frequently the finger print sensor and app failed to allow me into my house. Once even the keypad stopped working and I was locked out of my house for some time as my key was inside the house. Another ding is no Apple HomeKit integration. I would return the product as I plan on removing it and buying a more reliable lock but the return time has elapsed. I rarely use my front door as I usually enter through my garage so I wasn't aware how unreliable the lock was until recently. Another issue I have is the key isn't a standard key so it can be a little difficult to have a copy made that will work. After some research I was told that the key they use isn't a standard size and can easily be mixed up for the wrong blank when a copy is being made leading to a key that is cut properly but won't fit inside your lock. Not sure how true this is but if you are having issues making a copy this could be the reason. If everything worked consistently this would be a good lock that I would recommend. Perhaps I just have a bad one. I would recommend testing it out and making sure you return within the window if you have the same issues I have. ... show more

    • Great lock that makes life easier
Color: Black Item Shape: Modern Set name: Deadbolt
It works well most of the time. I enjoy not having to bring keys and being able to give guests their own access code. It frequently fails to lock in the winter; you have to push the door shut when the inside and outside pressures differ. Maybe it’s my door that is the problem and not the lock. A slightly annoying feature is that it will lock the door even when I just went through it. The timer is based on when it was unlocked and has no idea that you are unloading groceries and will be going through it over and over. Not a deal breaker though. It takes 8 AA batteries, which lasted about 9 months. A rechargeable battery pack would be nicer. Overall, I'm very happy to have it. The installation was simple; it took about 15 minutes. It's really nice not to have to dig out keys or get locked out if you forgot them. ... show more

    • Great App, but Serious Battery Drain Across Multiple Eufy Locks
Color: Black Item Shape: Modern Set name: Deadbolt
Review Image by Camy Tran
I’ve been using Eufy smart locks since 2021. I manage Airbnb rentals, and because I liked the Eufy app and how easy it is to create and manage access codes remotely, I ended up installing Eufy locks on multiple rental properties. Unfortunately, the battery performance has become extremely disappointing. My older Eufy locks initially worked well, but after about two years, the batteries started draining much faster. They would last around 45–60 days, and over time the battery life became shorter and shorter. The two C210 locks I purchased in 2023 are especially frustrating. They sometimes disconnect from the app because of “low battery,” or the app sends a low-battery warning even when I replaced the batteries only 2–3 days earlier. I first used regular alkaline batteries, but they drained so quickly that constantly buying batteries for multiple locks became expensive. I then tried rechargeable batteries, but the experience was even worse, especially with inaccurate battery readings and connection issues. What disappoints me even more is that this is not only happening with my older locks. My newer Eufy lock purchased in 2025, which requires 8 batteries, has the same battery-drain problem. I have to replace all 8 batteries approximately every 60 days. That is a lot of batteries for one door lock. I even followed Eufy’s troubleshooting recommendations to reduce battery consumption, including turning off features such as auto-lock, but it has not made a meaningful difference. The batteries still drain far too quickly. For an Airbnb host, reliability is extremely important. I need to manage guest codes remotely and know that the lock will stay connected. Having to worry about a lock disconnecting, receiving incorrect low-battery warnings, or replacing 8 batteries every couple of months defeats much of the convenience of having a smart lock. I really like the Eufy app and have stayed with the brand since 2021, which is why this is so disappointing. After experiencing similar battery problems across several Eufy locks purchased in 2021, 2023, and even 2025, I no longer feel this is simply an issue with one defective or aging lock. Eufy really needs to address the battery consumption and inaccurate battery-level reporting. I would like to continue using Eufy, but at this point I’m hesitant to purchase another Eufy smart lock unless these battery issues are resolved. ... show more

    • C220 is the best Eufy smart lock they kffer
Color: Black Item Shape: Modern Set name: Deadbolt
I've tried the higher end palm reading smart lock and it was a complete nightmare. Everybody was either getting locked out or took over 20 minutes to get inside. It then decided to start malfunctioning This one however just works and was easy to set up. Setup was super easy and you can get in quickly It works with all your smart devices and if you already got eufy equipment you are set It has all the needed features the higher end ones have without any of the extra garbage that doesn't work consistently. It's nice to be able to set up temporary codes and fingerprints for people. That would come in handy if you have an air b&b you are renting out and want codes to expire or if you have a cleaning lady or dog sitter. You can remotely unlock the door from your phone at work if the Amazon guy needs to get a package out of sight. I have mine hooked up to my alexas so if I forget to lock one of my doors I can ask her to do it. Highly recommended. Oh, and have a pro locksmith install I it's worth the fee as they'll make sure the unit is installed correctly and the dead bolt has a big enough hole before calibration. ... show more

I purchased the Eufy Smart lock along with 2 others off of Amazon at the same time. Hands down, the Eufy was the best in craftsmanship and quality. It took about 30min to have it installed. It fits the opening of my other regular deadbolt. It not only makes my condo door look more appealing. It's well made and sturdy and heavy. Setting up the phone app only took about 15min and it's very easy to use. I have had 0 problems with the finger print funtion, one time every time. I love the code support option keypad that my family use. I was able to set up individual codes and even if there not used daily, there haven't been any issues. Even though there is a 2nd knob key lock. I really don't have to use it, because the deadbolt is very tight and secure. The batteries that came with it is still working and shows that the batteries want need to be changed for months. I set it to auto lock and without fail it does everytime. I keypad lighing is great day and night. I don't have to double check it. You can adjust the lock volume. So , I have it loud enough to hear someone coming in, but not alarming. I love the app, because, not only does it notify me that my door is locked when I leave, it alerts me when anyone else does as well. It was more expensive then the other two, however it's well worth the price. As far as installation. If you lay everything out and follow the instructions it's quick and easy. Or you can use Utube. Depending on your bolt hole if you're using the same one, you may have to chisel it out some as the bolt is longer. However, even with doing that it on took 30 min. Initially he didn't and it worked, however chiseling it out with a screwdriver, made it very secure. Money well spent. So impressed my neighbor across from me purchased one. I've been wanting to get one and kept putting it off. This lock has changed my life, with limited use of one hand. I don't have to dig in my purse, I can unlock before getting to the door. After, I enter it locks behind me. I do keep a key on my key ring for back up just in case. Well worth the price. This is a purchase that you want regret. ... show more

    • Great keyless entry system!
Color: Black Item Shape: Modern Set name: Deadbolt
This is our first experience installing a keyless entry system. The installation was very simple and took no longer than 20 minutes. We just started using it a week ago, and some of the fingers I registered for fingerprint unlock don't work, but I also have quite sweaty hands. I think I may need to re-register some of them. But the codes work flawlessly. It's so convenient not having to take a key out with you. We give our house cleaner a code that is only valid on the days she comes, and it's worked well for us. The app is also very useful in letting you know who is coming in and out of your house. I just hope the battery life is as long as advertised, so we'll see. ... show more
