eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock

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.

Great price for a solid well designed product. I looked at a number of locks like this one, but none matched the features, price and quality I wanted. This is my first Eufy product and so far so good. High quality and a pretty easy install and setup. Make sure this will fit properly in your door. See the measurements provided by the company. The app is really pretty easy to use and I love the auto locking feature and the ability to temporarily assign a code to the person that takes care of our cats while we are away. It keeps a log of all the ins and outs and it also had alerts that let you know if the lock is being used. I need to take the time to fix the weather stripping our door so it closes completely, because sometimes the lock can't lock because the door is not fully closed. That is the fault of the door, not the lock and the cool thing is that the app tells me when it tries to automatically lock and failed. The only negative I have seen is that on a rare occassion, the lock seems to glitch when I go to lock it when leaving the house. I just wait a beat and then put my thumb on it again and it works great. The lock looks great and seems to be well built. We use it with Alexa as well and it was easy to integrate into the Alexa app. Fingerprint recognition is the same as what you do on the phone and it has never failed for any of us. We no longer have to worry about making keys or losing them, but it does come with a key in case there is an electical issue of some kind. I am really happy with this purchase from a price to quality and features perspective and highly recommend it.

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.

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.

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.

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.

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.

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.

Está increíble. Se siente de excelente calidad, es robusta y, al mismo tiempo, muy intuitiva y fácil de instalar y configurar. La app está muy bien optimizada y permite configurar prácticamente todo. Usa 8 pilas AA; al principio me parecieron demasiadas, pero después de escuchar la potencia del motor al bloquear y desbloquear la cerradura, se entiende perfectamente. Antes había comprado otra cerradura de otra marca, pero terminé regresándola. Después compré esta y superó por mucho todas las expectativas que tenía. La detección de huella es rápida y precisa. Cada usuario puede registrarse con su propio PIN de acceso, y la app notifica siempre quién entra, además de indicar si la cerradura se bloqueó de manera manual o automática. Incluye dos llaves de emergencia y todo lo necesario para instalarla, excepto el desarmador, obviamente. La recomiendo 100%. Se siente como un producto bien pensado, de muy buena calidad y con opciones de configuración.

I’ve been using the eufy Security Smart Lock C220 for a few weeks now and overall I’m really happy with it. Installation was easier than expected and took me around 25–30 minutes with just a screwdriver. The instructions in the app were straightforward. The fingerprint reader works surprisingly well. It unlocks quickly most of the time, even when my hands are a little damp or cold. I also like having multiple ways to unlock the door, fingerprint, keypad, app control, or a physical key as backup. The built-in Wi-Fi is a big plus because I didn’t need to buy a separate hub. The app has been useful for checking if the door is locked and for letting family members in remotely. Notifications are fairly quick too. Battery life seems solid so far, although I haven’t had it long enough to confirm the full 8 months yet. A couple small downsides: the keypad can be slightly hard to see at night unless the porch light is on, and the app setup took a few tries to connect to Wi-Fi initially. Once connected though, it’s been stable. Overall, this feels like a good balance between price, convenience, and security. It’s a great upgrade if you want keyless entry without spending a fortune on a high-end smart lock.

Works exactly as stated and no issues as usual with Eufy products.

This work surprisingly well very impressed.

Instalación rapida y sencilla. Funciona muy bien .
