I already own multiple eufy products (cameras, outdoor lights, etc.), so adding this lock was a no-brainer. Having everything in one easy-to-use app is super convenient and makes managing my home simple. The fingerprint unlock is fast and reliable, and the remote access adds great peace of mind. Customer service has also been excellent—quick to respond and very helpful. Installation wasn’t the easiest, even with the instructions, and took some patience. But once set up, the lock works flawlessly. Overall, a great product that fits perfectly into the eufy ecosystem!

I started looking for smart door locks for our new place after getting tired of fumbling with different keys for the front and garage door locks. I could have gotten the locks rekeyed, but I decided to install smart locks on the two doors and get rid of keys altogether. After getting used to fingerprints to unlock and log into most apps on my phone, I just couldn't get myself to buy a smart lock without fingerprint support. The Eufy touch lock seemed to be one of few fingerprint smart locks out there backed by a well known brand, but it didn't come with wifi support. I heard the wifi version was coming, so I decided to wait a couple of months and finally took delivery of the updated locks last week. The locks are pretty easy to install, and come with good instructions and well labeled/organized parts. The locks took about 15 mins each to install. The app is also pretty easy to set up, and I can log into the app with fingerprints on my android phone. The one setup quirk I had to deal with is that selecting the "touch lock with wifi" when adding a new lock to the app didn't work. The QR code scan wasn't doing anything. I noticed that the product code on the lock was not 8520, but 8510, which is the same code as the non wifi Eufy touch lock, so I decided to add the non wifi touch lock to the app. This time, the QR code worked, and I was able to add the included wifi bridge separately and pair it with the lock. This should be good news for those of you who have the regular touch lock, as it indicates that you will be able to add Wifi support when/if Eufy starts selling the wifi bridge separately. I programmed each lock to unlock with three different fingerprints, and have been very happy with the responsiveness of the fingerprint scanner. It seems to be faster than the under screen fingerprint scanner on my Samsung Note 10+. The unlocking process with fingerprints is extremely quick and seamless. I also added my wife as a separate user, so she was also able to register her fingerprints with each lock. Each user also gets to select a 4 to 8 digit pin code (different code for each user). The app lets you customize a lot of things, including auto lock functionality (lock after duration, auto lock schedule with start/end time), wrong attempt timeouts, lock sounds, scramble pass code (add random numbers before and after your actual pin to hide it from prying eyes), etc. I've only had the locks for a few hours, but I have been very pleased with how well they work so far. The only minor annoyance is that one wifi bridge cannot connect to more than one lock, so if you have two locks like I do, you will have to have two wifi bridges operational. It would have been nice if the wifi bridges supported multiple locks, but it's not a deal breaker.

NO HUB OR GATEWAY NEEDED. The lock was simple to install. The one issue I had was to get it to connect to the Wi-Fi, I had to power it up, not in the door, closer to my router. It seemed that the location that I was installing the lock was too far from the router, it would not connect to my router. When I took the lock off the door and laid it on the kitchen counter, near my router, it connected. Then I took it back out to my walk-in garage door, installed the lock and it connects to my Wi-Fi, go figure. So if you are having trouble with the initial setup and the lock does not connect to your Wi-Fi, remove it and move it close to your router and get it to connect, don't complete the setup at this point, stop as soon as it connects to your Wi-Fi then put it back in your door and finish the setup. Not sure what the issue was, but now it connects to the Wi-Fi. Everything works great. Fingerprint works, put mine and my wife's fingerprint in, works. Codes work. Remote access works, drove several blocks from my house, had the wife stand at the lock and observe, and I was able to lock and unlock the lock. Connected the app, or lock, to Alexa and it works. You need to open your Alexa app and get the settings, set. I have, had, another lock, but you need a hub located within 10 feet of the lock. This lock, no hub.

I bought this lock to replace a Kwikset smart lock that had abysmal battery life. Installation was very straightforward and the app is very well designed imo. The fingerprint capability has worked flawlessly and the lock construction and quality is very good. The WiFi connectivity and stability has worked very well in my situation. I have 3 locks installed. This lock was highly rated by consumer reports and thus far I would concur. I will see long rem if the touted 1 year battery life pans out but very pleased thus far…

This is a review for the Eufy Smart Lock Touch with Wifi Bridge. just got this device today and my 12yo and I installed it. Installation of the unit on the door itself is easy. However you may need to take some extra time to get the lock plate lined up correctly. In my case it would close manually ok with the old lock plate, but upon connecting the device to bluetooth and "calibrating" it would error. I switched to the included door lock plate as it is a little larger but still had to chisel a little of the jam out. Nothing major but after getting the plate aligned correctly works very well. Maybe took 40 minutes with needing to do modificaitons. Next, the wifi bridge was a little futzy, it did not want to flash green after holding the sync button, unplugged unit and plugged back in still only red. I had to push in the reset button and got it working but this portion was a little slow. I originally had Bridge about 14 feet from Smart Lock and read as a "poor" connection or something like that. I moved it too about 10 foot away (closest plug I have) and seems fine now, although did work at the14 foot spot as well. So for some depending on where your door and an outlet is for the bridge it could be an issue. I have only used it for part of a day but so far the fingreprint reader has been reliable, needing only a few retry's. The lock and unlock function in the app is responsive, less than 10 seconds to unlock A main reason for me wanting this Smart Lock over others is I already use the Wifi video doorbell (version that connects to old wires and homebase) and home security door sensors. I have been very happy with those devices. I had bought a coupon to get this unit on a preorder for $159 so was very reasonable. Now that Eufy has a direct wifi connection smart lock, users who don't have an electric outlet close to the door where the smart lock will be placed may want to consider the Smart lock with Wifi built directly into the unit. My biggest concern is how will the Smart Lock/Bridge/Wifi connection stays coonected, or will it be something I have to fix periodically. I am unsure what other devices the bridge that came with this device connect too.

Buyer beware. Buy these eufy locks for manual use or bluetooh use only. The Wi-fi in these locks constantly lose connection with your network and the phone app. The phone app constantly hangs for can't connect to the lock, though you may be able to lock and unlock it over wifi. When researching the Internet, this has been a known problem for years. The eufy support is responsive enough, however, they have no fix and there doesn't appear to be a fix in sight. Easy to install, and when it works it's great. It just doesn't work, for anybody, consistently for for very long. You will see the image I have attached, more than you will be able to use the locks over wifi. Two stars. One because it is very easy to install and one because the physical deadbolt works. If you're looking to use and control this over Wi-Fi, look elsewhere. **Update 8/6/25** Updating review to update rating from 2 to 3 stars as the eufy technical team continues to try to resolve the issues including releasing new firmware that has improved connectivity. I will continue to update the review based on the long-term effectiveness of the bug fixes. **Update 8/7/25** Firmware bug fix has be me up overnight. That has never happened before so I'm going from 3 to 4 stars. Excellent technical support response. Maybe it wasn't ready for Wi-Fi 7. But I'm happy to be able to now use wi-fi. If this remains stable for a few months, I'll happily edit one more time to give it 5 stars. **Final Update 8/8/25** Connectivity over Wi-Fi lost again. Yet the $7 Wi-Fi Lightbulb above the door has remained connecting and functional for over a year. I'm not going to factory reset and try again and wait for more fixes or upload more logs. I'm going to look for an alternative product. I cannot recommend and leave this with 1-star. Now I wonder if I'll be able to rely on eufy's security cameras.

Great lock, I first installed it on December 2025. It is now April 2026 and I just lost 1 bar on the battery. The battery has 5 bars when fully charged. I had a smonet that I would just to keep buying batteries. The batteries would die after a month and this is from using lithium batteries. Then one day the finger print stop working. But the eufy is everything and more. I love it

I have always wanted to get a smart lock so I wouldn't have to deal with keys at all and neverhave to worry about getting locked out of the house. I recently stayed at a luxury condo at an Airbnb and it had a Yale pin pad smart lock. It was amazing not having to use keys so I decided to finally just go buy one. I researched for hours to find the best smart lock for me, and the Eufy smart lock hands down won. I loved all the features especially the fine print reader. They have a newer model with built in wifi, but this one was much cheaper and since it came with the bridge it does everything the newer model does- but more! With the bridge it had a SD card slot that can record video with Eufy security cameras. I love that so your not having to pay for a monthly subscription for cloud storage. It also acts as a speaker for Eufy doorbell. My phone has a finger print reader which I always use, it takes a second or two to recognize and unlock so I was wondering if this would be the same, or slower. That's why I liked that it also has pinafore for a code, or even an actual key if the batteries happen to die. It does have a USB jack on the bottom so if the battery dies you can hook up a power bank to it. I was pleasantly surprised that the finger print reader works extremely well and fast! It gets it right the first time every time and works almost instantly. I love it!! I am working on making my whole house a smart home, I have all the main rooms completed so I love that using the lock can trigger smart home routines to say turn on all the lights and turn TV on. The Eufy lock looks and works better than the Yale lock on the condo that is more expensive. I love literally everything about it from the design, build quality and feel, and the best part is no more keys!!! It's very cool that it comes with extra security-it has an extra sturdy door latch that screws in deeply to the door casing and wall to make it a lot harder for someone to push the door in. Another favorite feature that I almost forgot to mention is the autolock feature! You can set the timer for 1 seconds to 3 minutes upon closing the door to when it locks. I have it set to 1 second and is perfect. It's nice that it has a door open/closed sensor built in- most smart locks either don't have it or is an extra sensor to attach to the door. That's great because it will only lock if the door is fully closed and will let you know if the door is not securely closed. It was very easy to install. I can't say enough good things about it. It was 100% worth the money! If you have been thinking about it but debating on if it would actually be worth it- the answer is yes yes yes get it! Lol You'll be so happy you did!
