eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock, Built-in Wi-Fi, App Remote Control, Front Door Smart Deadbolt, IP53 Waterproof, 8-Months Battery, Nickel

I’m very impressed with this Rudy smart lock. It looks modern and elegant on the door, and the quality feels solid and reliable. Installation was easier than expected, and once set up, it works smoothly every time. I love the convenience of keyless entry—it makes daily life so much simpler, especially when you’re coming in with your hands full. It responds quickly, locks securely, and gives great peace of mind. The design is clean and minimal, which fits perfectly with a modern home. Overall, a great upgrade for both security and convenience. Highly recommend!

This lock was easy to install and set up with our Google Home. It works well. It locks automatically after 30 seconds. It unlocks and opens easily with our fingerprints, so we never need to enter the numeric code. The batteries have lasted for well over 6 months and they're still going strong. That's one fewer key I need to carry. I can also ask my Google Home devices if my door is locked, so I don't need to go to the door to check. UPDATE: I installed this lock in September 2024. It's now August 2025 and I just received my first "low battery" notification. The original 8 Anker AA batteries that came with the lock lasted for almost a whole year of regular use in our front door. I replaced them today with 8 Amazon basics AA batteries. Replacing the batteries was super easy. No tools were required. The lock is still working great. It locks and unlocks with our fingerprints quickly nearly every time. It's so easy to use our fingerprints that we never use our code.

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.

Seamless Eufy Ecosystem Integration, Quick Operation, But Inconsistent Fingerprint. ​As someone who has over 10 Eufy devices, this Smart Lock C220 integrates seamlessly into my security setup. I give it a solid 4 stars. ​Ecosystem & Convenience: The integration is fantastic, and the overall reliability makes sure [we are] never locked out of the house. The quick operation is essential for daily use, and the App remote control works perfectly. ​Installation: Setting this up was surprisingly straightforward. The easy install meant we had it up and running quickly, which is a major benefit when adding a new device to the ecosystem. ​The Drawback (Why 4 Stars): While the lock is excellent, the fingerprint recognition is inconsistent. It only recognizes my fingerprints to unlock, not my wife's. She has to consistently use the pin code instead. This frustrating glitch prevents a perfect 5-star rating. ​Despite the singular issue with the fingerprint reader's inconsistency, the security, ecosystem integration, and quick operation make this a very strong choice for Eufy users. I definitely recommend it for the peace of mind and convenience it adds!

This smart lock is ultra premium. It works flawlessly and was so simple to install and set up. It paired with our WiFi almost instantly, and it works perfectly with Alexa. The fingerprint scan is so helpful - it makes it quick and easy to get in the house (or lock as you leave). It also allows a code to be stored so that entry can be gained without a fingerprint. My husband and I scanned our fingerprints so quickly and easily - it was simple and effortless. The eufy app works great, too. We love this lock and are so glad we bought it. We highly recommend it.

I spent over $400 on what I thought was a full Eufy home security setup. I bought the HomeBase 2, the 5-piece sensor kit, smart lock, doorbell camera, outdoor camera, chime, and more. I expected to feel safe in my home. Instead, I got a system that can barely be heard and a support team that doesn’t even understand how their own products work. Only the HomeBase 2 makes a sound when the alarm is triggered. None of the sensors, cameras, or other components ring. Just one small box with a 100 dB siren sitting upstairs next to my router. I live in a two-story home. One day the alarm rang for hours and I didn’t even notice. Neither did my neighbors. What kind of security system is that? When I contacted customer service, I explained everything clearly. I gave them the facts, the issue, and the exact solution. Their replies were insulting. They asked me if I had tried turning up the volume. I had. They told me to try different alarm tones. I had. They told me to move the HomeBase, even though I clearly said it had to stay next to the router. Then they told me to use my doorbell camera as a siren, which is connected to a chime and would go off with every passerby. It’s not even linked to the HomeBase alarms. That suggestion made no sense at all. Then came the most ridiculous part. They actually asked me if my house had walls. Yes, my house has walls. That’s how houses work. If your product can’t be heard through a wall, it’s not fit to be called a security system. It got worse. They asked if my motion sensors and entry sensors made noise. These devices do not emit sound. They never have. It’s shocking that their own support team doesn’t even know how their products function. That’s basic information and they clearly didn’t have it. They also told me Eufy doesn’t make a separate siren. I had to send them a link to their own siren listed on Amazon before they even acknowledged it existed. I asked for two of them to be sent to me as a fair resolution. After dodging the request with emotional reassurances and irrelevant replies, they just stopped responding. To make things even more frustrating, one of the cameras I bought wasn’t compatible with the system. I only found this out through trial and error, because the product description doesn’t mention it. Nowhere does it say it won’t work. That’s on them. There’s no actual customer service number. You’re left emailing support reps who don’t read your messages, don’t know the products, and give you useless copy-paste responses while stalling you into silence. I handed them the solution. I explained the problem from day one. I did all the work for them. The moment I had an airtight case and knocked down every excuse they had, they disappeared. If you want a system that’s reliable, loud, and backed by people who care about your safety, this isn’t it. The design is flawed, the listings are misleading, and the customer service will waste your time until you give up. I regret buying this. You will too. Update: After weeks of trying to work with Eufy support, I was offered a refund that doesn’t even cover the cost of fixing the problem. I asked for two sirens so the system could function properly, or a refund to cover the actual price. They refused both and closed the case. Since I pointed out the siren was on Amazon, it was suddenly removed and now only shows up on their website. I gave them every chance to resolve this and they chose not to. Think twice before trusting this system to protect your home.

Works as advertised, which is a bit more than I can say of other smart locks I have tried (names witheld protect the innocents). Internet Access is fast and reliable, installation went without a hitch (again, not something that all smart locks manage to do), batteries seem to last a good bit (I have had it for two months and the regular Alkaline batteries are still showing 100%) and it is easy to change the access code. We use it with an Airbnb rental and I am quite satisfied.

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.
