HUB Requires minimum Aqara M2 type
Firstly HUB Requires!!!!! Only Bluetooth usage just so annoying. Connecting to Bluetooth method press the keypad any bottom what is located outside the door panel. Auto lock settings. Press the keypad, connecting Bluetooth and then setting available. Fitted the keypad and smart lock takes 5 minutes work for UK doors ( note!) lifting door handle required by human for operation the lock. Adding users finger print on the Aqara app easy and straightforward, works accurately and fast. Setting up the lock for smart home takes 2 days for me. QR code should work easy but it’s not! I thought it’s connected to the system but it’s not. So much additional settings must be done before the lock would be online. I’m using the lock with Aqara hub M2 connect the hub with wire to eero6 router making sure the connection is existing all the time to the lock. Ecosystems what I’m using with are Apple home, this was the easiest one I would say although the matter was trick me few times and needed to reset the lock several times. Alexa+ now this is the real challenge for setup but possible. Lock now works remotely, smart home integration not easy but ones is set up works shamelessly. Driving home, parking on the driveway saying to Siri I’m home, Siri opening the door while I’m get out from the car. Morning time going to work just saying Alexa open tue door lock, Alexa asking the access code ( can be avoided the access code with Alexa) and open the door. Driving to work asking Siri through CarPlay what is the front door lock status? Siri respond door lock. So yes once the lock set up properly will work shamelessly. Strong and good lock. Bit bulky inside the door but can be used to.

Too Big, Too Clunky, Too Unreliable — Back to Yale!
My Yale Conexis failed after eight good years, so I decided to try something different. Big mistake. I was tempted by the Aqara U200’s lower price compared to Yale, plus the added fingerprint reader. I did my homework, upgraded my door with a new handle and euro cylinder, and placed the order. I knew the mounting method was a bit odd — sticky pads and grub screws clamping onto the lock — so I even 3D-printed a custom part and screwed it in properly. But the problems started immediately. It’s so bulky that when you pull the handle, your knuckles smash right into the lock housing. Even my 13-year-old’s fingers couldn’t avoid it. Then came the actual locking. My door and new euro cylinder work fine; they’re not stiff, but there’s a slight notch where the bolt engages. My old Yale struggled a bit with this too, but never failed. But the Aqara’s calibration process couldn’t handle it. It kept thinking that notch was the end of travel, so it wouldn’t fully calibrate. They do offer a manual calibration mode — great in theory — but the lock just forgets it. If my wife hadn’t taken a physical key “just in case”, she’d have been locked out the first day. I came home, used the fingerprint reader (which is genuinely handy), heard the motor whir — and the door stayed locked. It either lost its position again or just assumes you’ll never unlock it manually so don't disturb the start and end positions. On top of that, manually turning it feels like you’re going to break something because it’s so stiff. In the end, the whole experience was so frustrating that it’s completely unusable for me. Back to Yale I go.

A Truly Superior Smart Lock Experience
Let me tell you, I've used a lot of smart locks over the years, and in my experience, the Aqara Smart Lock U200 is in a league of its own. From its sleek silver design to its seamless integration with just about every smart platform out there—Apple Home, Google Home, Alexa, and SmartThings—this lock has it all.One of the standout features for me is the fingerprint keypad. It's not just about the added convenience, but the responsiveness. I remember one chilly morning when I was juggling a coffee cup and some groceries. The last thing I wanted to do was fumble for keys. With a swift touch, the U200 had me inside and warming up in no time. It's these moments that really elevate a smart lock from good to must-have.Plus, the inclusion of the Apple Home Key feels like they went the extra mile. If you're an Apple user like I am, you'll appreciate the fluid integration that doesn't miss a beat. Battery life has always been a concern for me with smart locks. However, the rechargeable battery of the U200 holds up impressively well under regular use. Come to think of it, it's actually been a few weeks before I last thought about recharging.What really seals the deal is that it supports Matter over Thread, which is proving to be the backbone of smart home future-proofing. I tend to think it's worth investing in tech that won't become obsolete too soon, and the U200 fits that bill perfectly.Overall, if you're in the market for a smart lock that combines functionality with future-facing technology, the Aqara Smart Lock U200 makes a compelling choice. It's the kind of smart home hardware you miss when you don’t have it.

Great Features, Some Setup Hiccups, but Best UK Option
I'm giving the Aqara Smart Lock U200 4 stars. After having two Nukis in a row, I got frustrated with both the pricing of accessories and the slow response to software issues. While this lock has had its issues—setting up with Matter can be frustrating and I've seen others on forums having similar problems—the key is to properly follow the setup instructions from power on, especially holding the set button. It takes a while but does eventually get there. I run this on a Matter network with an Apple TV 4K and Home Assistant, and it works great. The software is actively being worked on, though it still feels slightly beta-like. There are a few features you miss with just a Matter setup without the Aqara hub, which is mentioned in the description, so double-check that you have what you need. In day-to-day use, the wife approval is high. The keypad, fingerprint, and HomeKey (which I love) all work flawlessly, with the fingerprint being the winner. The upcoming iOS 18 update this autumn adds Apple Home guest HomeKeys, which is a cherry on top. Overall, even though this smart lock has a few software updates to go before reaching its peak, it's without a doubt the best on the market for the UK. Until we get a solid option to handle multipoint locks, this is unquestionably the best UK option.

best smart lock
There are some important factors I consider when buying smart products (whether it's a camera, doorbell, lock, etc.): No subscription required Apple Home support No need for additional accessories (like a keypad, fingerprint reader, or hub) It should look good Reasonably priced This product meets all of these criteria. Installation: I've installed several smart locks before, and this is one of the easiest and quickest ones I’ve worked with. If you have trouble, you can watch the official guide or a video from YouTubers. It only took me 5 minutes to install. Setup: If you're an Apple user and plan to use it with the Home app, it’s crucial to add the lock to the Home app first, then to the Aqara app. If you don’t, you won’t be able to use the remote lock features, as those require the Aqara hub. Once it’s added to the Home app, you can lock and unlock it remotely. After adding it to the Aqara app, you’ll need to adjust a few settings, like calibration (make sure to auto-calibrate), latch mode (based on your door type), as well as the speed and sound of the lock. The only downside, which isn’t Aqara’s fault, is that in the Apple Home app, you can only lock or unlock the door. There's no option to retract the latch when the door is unlocked. This is due to a limitation in Apple’s system, but there are rumors that Apple will update this feature soon.

Terrible quality control
On paper, this looks like a good solution to add an intelligent lock to my door - one of the only ones that would fit. Unfortunately, the vmbuild quality is abysmal. I have tried to install two now, only to discover that both suffered from (different) factory defects. If Aqara can't be bothered to do quality control before shipping, they could at least distribute an information sheet to tell purchasers how to spot defective items bore going through the trouble to install: if the thumbturn doesn't rotate freely out of the box, don't bother going any further and return the lock. Then, invoke calibration before installing. If the lock can not be seen to turn, it's defective, return it. Other notes: the unit is made of silvery plastic (not chrome metal), which isn't apparent in pictures. Set-up is fiddly and confusing, with various different QR codes, no clarity as to why one QR code is failing or Bluetooth not connecting.

Easy to install
Works really well. Installed over key, fixed firmly with grub screws and feels solid. Keypad with finger print recognition works reliably and quickly. Paired with Smart Things via matter and does all I need it to. For more tinkering in the Aqara app you need to be within Bluetooth range ie at home, but for the most part don't need to bother with Aqara app and can do all I need via Smart Things. Lots of functionality, some of which is limited if you have to lift the door handle before engaging the lock. Generally works quickly. Does make a bit of a grinding noise ie is loud but where I have it it doesn't disturb anyone.

Do not be deceived!
First of all.. i don’t normally write reviews but as this lock cost to much i felt it was necessary. The Bad: The build quality of this lock is not worth the high retail price this being sold at. The plastic is very thin and i do feel it will age badly; especially the outdoor keypad which feels like a toy. Getting this to pair to HomeKit is very troublesome but after my 9th attempt, it paired.. only to show up as “no response” the next day. Leaving me with no option other than to reset the entire device. The adaptors that come included with the lock are of very poor quality and i dont think they would last more than 6 months before needing replacing. While my lock was operational, it would constantly show as “locked” when in reality the door wasn’t. This is after my 30+ attempts at both automatic and manual calibration. It’s not been installed more than a week and now the lock will not lock the door but shows as locked in the app. The thumbturn doesn’t even move. I’m unsure if this is hardware or software related It’s very unfortunate that in order to gain all additional features you need to have also purchased the recently released the HUB M3. My lock has effectively turned into a paperweight as i cant trust it to secure my door. The pros: After enough of my above moaning, its good that we now have a Homekey lock in the UK (shame that Apple dont let you share the NFC key from your wallet, only sharing a PIN code at present) I could have a defective unit, in theory, it’s the complete package meeting all of the unlocking protocols you could want pin, fingerprint, nfc and key. While it worked i was impressed that the lock could tell when the door was shut without needing an additional magnet on the outside. The sticky pad that the unit sits on is so adhesive it should be used on spacecraft The amount of mounting solutions included in the box is impressive In summary, as the owner of many Many smart devices, i am somewhat disappointed in the unit itself and the build quality, don’t heighten your expectations set by the price. It’s priced as such because it’s the only one that supports all of the protocols and Homekey.

Pratico, semplice da installare e ben integrato con HomeKit
L’estetica non si discosta da quella di altri marchi (vedasi il Linus Smart Lock di Yale), e lo spessore del dispositivo può precluderne l’utilizzo su alcune porte, ma la funzionalità, una volta installata, non ha da invidiare alle controparti di altri brand. Il montaggio è semplice, grazie sia alle istruzioni chiare che a una buona ingegnerizzazione del prodotto, e la configurazione iniziale è rapida e quasi del tutto automatica. Il tastierino compreso nel pacchetto rappresenta un’aggiunta di valore, specie in considerazione dell’integrazione che aggiunge nei confronti del sistema domotico Apple. Il dispositivo infatti è perfettamente funzionante con Apple HomeKit, e supporta anche la chiave di casa digitale utilizzabile tramite Apple Wallet sia da iPhone che da Apple Watch, con tutte le (positive) implicazioni del caso. Ciò naturalmente non sovrascrive ma si aggiunge alla possibilità di sblocco tramite impronte digitali (multiple, configurabili per ciascun utente impostato) e di combinazioni numeriche. La reattività della serratura all’input del tastierino è immediata. La rapidità nel blocco e nello sblocco è molto buona e la rumorosità più che accettabile, per quanto probabilmente risulti un po’ meno silenziosa della controparte Yale. Aqara continua a ritagliarsi uno spazio sempre maggiore negli ecosistemi di domotica, specie in quello Apple che troppo spesso resta orfano di supporto da parte molti brand.

Con defecto de fábrica y Sin posibilidad de hacer la devolución.
Me llegó defectuosa, ya pedí el reembolso, pero no la he podido regresar por qué la etiqueta que me enviaron es para uso en EEUU y supuestamente me van a enviar una etiqueta nueva para el envío. ¿Será? Se acerca la fecha límite para hacer la devolución y nada.

Totally unreliable, don't waste your money
Just an FYI: This is not my first smart device. I have years of experience installing and using Z Wave, zigbee, ip based and matter devices. My network has a dedicated IOT wifi with excellent strength. Below is my experience which conflicts with the youtube reviews of various popular fanboys. Problems with the Aqara U200: 1. it comes with NO instructions, refers you to online help, which is useless. 2. the lock is entirely setup with the Aqara app, basic on/off only on your platform. In order to change any settings you have to go to the door, open it, and press the outside keypad - otherwise the app does nothing. Which is a big waste of time and hassle. 3. the lock adjustment has two methods: manual & auto. I made a huge number of attempts to fix the locking problems using both methods, and the lock continued to work only when so inclined. 4. the key requirement of a smart lock is easy and reliable locking & unlocking. This lock works if it feels like it. Leaving me locked out on several occasions, or not locking on many others. The various lock after delay settings did not work at at all. 5. I wasted a lot of time installing and trying to get it to work reliably and after returning it was left with damaged paintwork at the front door, from unsticking the keypad.

Basically dead in less than a year
9 Apr 2026 Edit: ok so I’ve had this since August of 2025 and today’s date is noted above. This device has been intermittently problematic and uncooperative. Sometimes it locks and sometimes it just says it’s locked. I’ve come home more times than I should have to find the door unlocked, but also with a text message telling me that the door had locked when I left. Yeah, the one thing that a door lock cannot be is unreliable. At this point I don’t trust the lock unless I have manually checked it. In fact I find myself using the key most of the time because of the next thing I’ll talk about The device now makes sounds as if it is *trying* to lock or unlock, but. It actually doing either of those actions. About half of the time the device will eventually successfully lock or unlock. The other half of the time the device will eventually give up and just send me a text that it is jammed. No, it’s not actually jammed. It does this when the door is open and there is no way it’s jammed. Also, sometimes if I just press the lock button again it will actually work this time. But really, it’s just more convenient to just use the key. This is unfortunate, since I bought the lock and the doorbell cam together as a pair. And this unit not functioning as intended has basically negated the utility of the doorbell cam as well. $400~ish that I feel like is wasted at this point. And for the record, I have removed the battery and verified that it is fully charged, so no, the problem is not a battery that needs charged. I have not tested the battery to see if it has dead cells or something unlikely like that, so I guess that is possible. But again, not very likely due to how batteries like this are constructed. I hate leaving this review and update to the review. I have a lot of other Aqara devices that work great and have been working great for years. This one device, along with the doorbell cam that was intended to compliment it, have been a pair of expensive disappointments. Original August 2025 review: ok i wont get too deep into the weeds here. let me say that the install was fairly straightforward with the exception of needing to remove and invert a little plastic fitting on the baseplate of the interior frame of the lock. once i figured that part out, installation went very quickly and easily! I also already have other Aqara devices in my house, so adding it to my existing account was fast and straightforward as well. frankly, i have devices from many manufacturers that i bring into home assistant for interoperability, and Aqara (Xiaomi in case you dont know) is one of the most polished and easy to use apps! The lock feels decently made, even though it is mostly plastic, that part is inside and not exposed to the elements, so not really a big deal. The keypad however is placed outdoors. so i suppose that we will eventually see how durable it is. i live in southern california, and the sun can be brutal. i placed the keypad in a protected location to mitigate sun exposure, but again, time will tell. i have used the numerical keypad, the fingerprint reader and nfc on my watch and phone, and all seem to work quickly and reliably. And it integrated easily into apple home and bridged into home assistant just as easily using matter over thread. HOWEVER, this device is advertised as having an internal gyroscope so that it knows when its closed. yeah, it doesnt know when its closed. all it knows is that its not moving. so when the door is open, itll lock itself and tell me that its closed and locked. thats not okay. that creates a situation which would be easy to mistakenly leave the door open thinking its closed and locked. worse yet is that i bought and installed the newest doorbell camera / hub alongside this device, which is advertised to work in concert with each other. and i suppose at the most basic level, they do. but nowhere near the level that i expected from this brand. i have other devices which have actual facial recognition, and can respond accordingly. even though i couldnt find explicit wording saying that this was a feature, i was confident that since it had been such a basic feature in much lower priced devices, that it would do so. if this isnt the reason, i dont understand why it has the ability to register my picture to the device? all of the drawbacks i found with this device can be fixed with software updates. and im hopeful that they will be. and despite the shortcomings, i would recommend the device. just know what it is that youre buying. i admit that i have higher expectations than just about anyone else will. but in todays smart home environment, i feel justified in having high standards.

Declared Apple HomeKit integration does not work.
The product is fine on its own and has good quality. The software component, however, is the main source of worry. I have spent four hours on the internet and in forums trying to get this to work with Apple HomeKit, but it doesn't. Instead, you must install the Aqara app, get all the features, and then hope that it works at all. I purchased this to replace my Nuki smart lock, but in the end, I installed Nuki again.
