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…

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!

A good lock.
About 5 months in, and both of my locks (I bought two of them) are still working great! The build quality is excellent; full metal construction, with an incredibly satisfying key door. One is on my front door, so full weather exposure (granted, the porch does offer protection) and it’s still just fine. I do wish the rekeyable cylinder was compatible with my other keys, but it’s not a dealbreaker — it is still rekeyable if you have the tools and the right kind of key. Battery life is good, haven’t seemed to have any problems there (locking & unlocking electronically 2 times a day, on average). Installing them was super easy, the instruction video was very clear (although I would rather have a paper guide; videos can be annoying when working on stuff). The mechanism is fairly strong, though it has a little bit of trouble if your door has weather strips (if the deadbolt makes contact with the hole in the doorframe, it may or may not be strong enough to lock, depending on how hard the weather strips push the door out of equilibrium). I haven’t really used the password, since most of the time I either use automated proximity-based locking and unlocking (not natively supported, I use Home Assistant) or my phone (the HomeKit virtual keycard is super slick and very handy). My one gripe is that it doesn’t support WiFi unlocking (and remote management) by default — you need a proprietary hub to get it to do that. I just picked up their cheap 20 dollar USB Zigbee hub and that did the trick. Overall, a very solid lock, and seems to be worth the money!

Best lock for apple people
I like this smart lock more and more. Set it up using the app, apple home and home assistant. Got it paired to a Aqara G410 doorbell and they work great together.I’m coming from a nest hello doorbell and Schlage smart lock. The home key unlock is awesome and the only way I unlock the door. I might get a u100 for my front door and move this to my side door so I can get the finger print scanner.Looks great on my door. Fits perfectly with my handle. Easy to set up the hardware and get it connected to everything.If you are an Apple person, this is the best lock for you. Homekey for $100

App destroys usability
I'll have to admit that I'm very frustrated right now, but it's true what the others have said. The app is absolute garbage, ESPECIALLY for Android users. It will pair but it disconnects Bluetooth immediately. I have tried to restart this three times, only to end up with the same result. I'm trying so hard to work around this. Here are the methods I'm currently using:I used the Homekit feature on my wife's iPhone 16 Pro Max, so she can use her phone to unlock the door. The rest of us in the family are using the PIN, because I couldn't set up the app on my Android phone on day one. Having said that, I felt my last workaround would be using my self-hosted Home Assistant would give me some relief due to this device having Matter, but NOOOOO. Of course Aqara goes against the standard and requires that you buy their stupid hub in order to fully utilize the Matter feature.This lock is fast and responsive, and it's a shame that the app is garbage.The other issue I've been having is visibility. This is actually two issues in one paragraph. It's bad enough that I have to WAKE THE LOCK before I can even input my PIN, but as someone who is severely hard-of-hearing, sometimes I can't hear the beep to know the lock is awake, and to make matters worse, it's hard to see the backlight activate during daylight; thereby, it makes it very difficult to know if the lock is awake or not.Finally, the last issue I've had with this lock: my technophobic mother-in-law could not get through our front door to drop something off when we were away from home. I don't know why, since Homekit is new to me, we couldn't remotely unlock the door for her, which made things more frustrating as she struggled to unlock the door and even set off the alarm (...lol funny now that I think of it).In this case, I would have set up a fob for her so that she wouldn't have to deal with this, but I can't set up a fob IF I CAN'T USE THE APP.So, everyone reading this, maybe you'll be able to get by on using the PIN and your Apple phones, but otherwise... Don't bother with this product. The hardware is great (except for visibility during bright days), but the app severely severely severely hampers the usability of this "smart lock".

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..

Good lock overall but with problems and concerns
Good lock overall but with problems and concerns:Problem 1: It took a whole village of effort to change batteries due to design of the compartment door and the tightness of battery holder (see problem 2). The battery compartment door is plastic... which is fine, but the door is held to the frame with the plastic clips on the door, to open you need to have a good fingernail or something to pry open the battery compartment door, to close you will snap the door back to the frame, I don't know how long the plastic will last to hold the door in place before it breaks. Use magnet to hold down the door will simply solve the problem...Problem 2:the battery holder is too good to secure the batteries, the holder is so tie that you will need to force the batteries in, then taking the battery out is the biggest issue, you definitely need a flat head screw drive or something strong to pry the battery out of the holder, don't try it with your fingernail. I have already broke one of the contact spring that holds the battery when I tried to get the batteries out, because the battery contacts are so tie and leaving almost no space between the battery and the holder.Battery life is OK with non-rechargeable lithium battery (about 5 to 7 weeks depending on usage) but poor with regular alkaline battery, only last for about 3 weeks.Interface of Aqara apps is terrible! functions are overlapping each other if you have other Aqara devices and it's so hard to find a specific feature, you have to drill down so deep to find things. However, if you have the device connected to Apple Home, then most of wheat you need can be down with Apple rather than Aqara apps, except some lock specific functions.

Perfect for Apple people
Typical Easy installation for a door lock. If you already have a lock you are replacing. Solid construction instructions are available online and print and video form. It’s nice not to have to do anything with your watch or phone to unlock the door. The key if needed is a standard 68 size replacement that can be copied anywhere.

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.

Very happy with Apple Homekey.
Been using this lock for more than a week. Homekey is very reliable with iPhone 12, 15 and Apple Watch SE. Installation is fairly straight forward. Build quality is very solid. I wish the battery door is easier to open - it need a pry tool and I am sure I will misplace the tool.App has a Homekit standalone mode which allows setting up the lock without an Aqara account. It pairs the lock with Homekit no problem. However, firmware update kept failing in this mode. I had to create an Aqara account to use the full feature of the app, then I was able to update firmware successfully.My HomePod mini is pretty far away from the lock at the back of the house, so querying lock status or unlocking from Home app take a few seconds. This is expected. I am actually surprised that it works over this long distance.

Not great for Apple Home integration - plenty of connectivity issues
Looks great at first and has very nice build quality, but it’s a nightmare if you can’t guarantee a strong Bluetooth connection between the lock and your primary Apple Home Hub (no WiFi.) I installed this for our garage side door to the outdoors so it wasn’t on the open level of our home near an Apple Home Hub. It only works when within range of our phone. Home Key worked most of the time, but status updates in Apple Home were horribly inconsistent.One option would be the Aqara hub but that only helps you with their own integration or for Google/Alexa. It won’t help with the Apple Home integration issues. We could never see the status accurately and automations constantly failed.Secondly, my garage side door gets morning and mid-day sunshine. The lock acted really wonky when in direct sunlight. It wasn’t especially warm to the touch or anything, and temperature was in low 20s Celsius. Even tapping HomeKey failed multiple times in these conditions.I’d recommend an alternative like Schlage’s Encode Plus, which has built-in WiFi for connecting to Apple home and their own Schlage Home app.

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.
