Reliable Budget Smart Lock
I absolutely love using my Apple Watch or iPhone to unlock my door, especially when I’m carrying groceries or my hands are full. I bought this smart lock because its description clearly states HomeKit compatibility. The setup process was incredibly easy, and you didn’t need to download the Aqara App to connect it to HomeKit. The auto-locking feature is fantastic; it locks the door within seconds of closing it. However, if it doesn’t lock, it’s probably because the door didn’t close properly. This particular model (U50) doesn’t have fingerprint recognition, which I don’t mind. Connectivity is excellent, and I’ve been using it for over six months without needing to charge it (I’ll charge it soon). I believe the battery life is quite good. I haven’t encountered any issues so far and don’t anticipate any in the future. I highly recommend it!

Looks great, functions properly, good price.
Bluetooth - checked, Apple home key - checked, Keypad - checked, Very clean look and functionality - checked, Price - checked. I was able to check all of my boxes with this lock. Simple, reliable (so far), no hiccups and relatively easy installation. The best part - you just bring your iPhone close to the keypad and it opens. No need to even turn your phone’s screen or go to the app - it works as a hotel key, just bring it close and it works. That’s what I was looking for when I did my research on the smart locks. The keypad is also great in case if you left your phone behind, no worries. It’s responsive and looks clean. I really like the overall design. It’s not bulky and feels right. What to watch out for: beware of a back lid where batteries live. It is HARD to remove. Every time I did, I thought I broke it. It’s tight and has nothing to do with how easy it looks on the instructions video. Believe me - it’s not the case. There is a little groove/slot to use the tool provided to open the back lid but when you do it literally feels like you are gonna snap it broken. Luckily it hasn’t happened yet, let’s hope it’s just the way it was designed and it’s gonna hold strong. But honestly - I’m not looking forward to the time I’m gonna have to replace the battery…

The best, but not quite there.
It is definitely one of the best options available as far as smart locks go without large tech companies have camera access to your property and door. The feature set is good, it looks great and the physical key works perfectly. Unfortunately the smarter features are a little bit inconsistent and it’s battery hungry. I have had to replace the AA batteries 3 times already after less than a year of ownership. Usually it works but occasionally it will fail to work with Apple Home Key, and sometimes takes a second to accept keypad input (very brief delay, not a big deal but does not inspire confidence). I would still recommend this to anyone wanting a smart lock until better options come out

WINNER WINNER
Wish I could give it a 4.5 star!!! The U050 is really good. Installation/Setup and connectivity was a breeze with HomeKit. There are some small quirks with the system such as wording/descriptions of features, weird times for automation/alerts and overall functionality. I would advised that after you install and setup to do a restart. I am renting my townhome so I will be looking to get the lock rekeyed soon. Homekey and Away button features are crucial and I love the integration with the Doorbell G4. AQARA always makes beautiful and quality products.

Works well, until it doesn’t.
The lock was easy to install and the app was fine, I primarily used it through HomeKit. The firmware update process was tedious, but didn’t have to do it too often so not a big deal. The real problem is that the front keypad (which includes Home Key functionality) failed after about a year and a half and warranty is only one year. Still works as a connected lock, but I have to either open an app and tap to unlock or use the physical key. Which defeats the purpose of why I bought it in the first place.

Great Smart Lock – Clean Design & Reliable Performance
The Aqara U50 is an excellent smart lock that’s easy to install, feels well-built, and looks sleek on the door. Apple Home Key works flawlessly—unlocking with my iPhone or Apple Watch is fast and convenient. The keypad is responsive, battery life has been solid, and having a physical key backup is a nice touch. It integrates smoothly with my smart home, responds quickly, and just works without hassle. For the price, the Aqara U50 delivers strong security, modern features, and great reliability..

Not great so far
Day 1 review: I bought this lock to replace a Yale Assure Lock 2 which completely died after only about a year. This was significantly cheaper and well reviewed so I figured I will give it a shot. So far I am not very impressed. The motor is super underpowered so I had to very carefully adjust my door so that there is no lock binding whatsoever. Even after I got it to have nearly zero friction I still got one failure to lock out of 10 attempts. The keypad is extremely slow, you have to wait a few seconds between each keypress or else it won't register. The gyroscopic door sensor does not work, it registers that the door is opened but then won't register that it was closed afterwards. The lock does not connect to wifi and can't be controlled remotely unless you buy the hub which is separate. To change the batteries you need a special prying tool; this comes with it but I feel like I am certain to lose this tool over time; not sure why this isn't just a normal sliding battery cover. You could probably use a normal screwdriver to pry the cover off but I feel like that would damage it. On the plus side, it looks great, it locks the door, and the apple wallet key thing is awesome. I'll give it a day or two to see if I warm up to it but right now it seems like I may need to return it. If I do end up keeping it I will for sure need to get the hub.

Unreliable auto lock
Auto lock when the door closes is unreliable. A third of the time doesn’t lock so have to be always on the lookout if door lock is triggered or not. Other than that it’s been good.

Reliable, Durable, and Seamlessly Integrated with Apple HomeKey
The Aqara Smart Lock U50 has been a fantastic addition to my smart home setup, offering convenience and reliability in a sleek package. Pros: Apple HomeKey Integration: Unlocking the door with my iPhone or Apple Watch is effortless and secure. Works flawlessly every time. Long Battery Life: Impressive battery performance, even in harsh Canadian winters. No more frequent battery changes! Keyless Entry Options: Multiple ways to unlock, including HomeKey, PIN codes, and physical keys for backup. Durable Build: Handles extreme weather conditions with ease while maintaining smooth functionality. Easy Setup: Straightforward installation and pairing process with HomeKit. Cons: Platform Preference: Works best within the Apple ecosystem; other smart home platform users may have limited functionality. No Remote Unlock Without Hub: Requires an Aqara Hub for remote access and advanced automation. If you're an Apple user looking for a reliable, weather-resistant smart lock with seamless HomeKey support, the Aqara U50 is an outstanding choice. Highly recommended!

Matter support is a joke.
Great lock unless matter support matters to you. This deadbolt never holds a connection to the aqara matter hub. Wish it had native matter support. Won't be buying aqara again.

Aqara Smart Lock U50 Review: The Door's Bouncer That Needs a Hub
First impression? This thing's got more tech crammed into it than a spaceship. It’s got keyless entry, Apple Home Key, Bluetooth, and even works with Alexa and Google Home. Basically, if you have a smart home ecosystem, this lock's like, "Sure, I can work with that." The Good: Keyless Entry: No more fumbling with keys like a caveman. Just use your phone or the keypad. It's like I'm in a sci-fi movie every time I come home. Multiple Entry Options: You can unlock it with your phone, Apple Watch, or even set up multiple codes for different people. Got in-laws visiting? Give them their own code and revoke it when they leave. Genius. Integration: Works with Apple HomeKit, Google Home, Alexa, and IFTTT. You can even set it up to unlock when your kid gets home from school. It’s like having a personal doorman. Security: This lock is no joke. Meets BMHA Grade 3 standards, which is solid for home use. Plus, you can rekey it if needed, so you’re not stuck if something goes wrong. Easy Installation: Comes with all the parts and screws you'll need. Just follow the QR code instructions and you're golden. The Bad: Bulky Design: This thing is a beast. It's like strapping a mini safe to your door. Not the most elegant, but hey, it’s a smart lock, not a fashion statement. Hub Required: If you want to integrate it with HomeKit or Google Home, you need a hub. More gadgets, more money. They get you every time with this stuff. Battery Life: Runs on four AA batteries. While they claim it lasts long, if you live in a place with harsh winters, you might be swapping batteries more often than you’d like. At least there's a USB-C port for emergency power. Overall, the Aqara Smart Lock U50 is a solid choice if you’re looking to upgrade your home security without breaking the bank. It’s got a few quirks, like needing a hub for full functionality and its less-than-sleek design, but the convenience and peace of mind it offers are worth it. I’m giving it 4 out of 5 stars because, let’s face it, nothing’s perfect, but this comes pretty close for the price.
