Fantastic smart lock - ideal if you're in the Apple Ecosystem
This smart lock has a range of compatibility options for various UK door locks. Installation was very easy and initial pairing to Aquara home app was easy enough - just ensure that you update firmware straight away. For Apple Ecosystem; if you wish to unlock with your watch/phone you need to ensure you have a HomeKit enabled hub that has thread border chip - the apple HomePod mini and later Apple TV with ethernet are required or upgrade your doorbell to the G410 camera which has the thread border hardware and you will find installation pretty straightforward so long as your WiFI signal strength and hub proximity are within range (true as of Sept 2025 at least). The keypad is well made and the finger print sensor is very responsive; giving additional access options as required. So far performance has been flawless once the calibration has been done - (it may take a few goes to make it consistent without error messages) Over all would recommend.

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.

Simply best lock on the market.
I can’t praise enough this lock. Very easy to install and setup. Very small delay to open, offers various ways to connect with different ecosystems, for me works seamlessly with HomeKit. Slick modern design. Thanks to great options in app it is easy to manage its sound as you can turn on quiet mode very easily and keep it working silently at night. Well worth the money.

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.

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.

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.

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.

Utilisateur depuis plus d'un an d'une serrure Nuki Pro 3eme et 4eme genération, j'ai fait l'acquisition de ce modèle afin de bénéficier de Apple Homekey avant tou et je suis extrêmement ravi! Tout d'abord les gros points forts: - Le prix! 199 en promo qui inclus le keypad lecteur de carte et d'empreintes alors que la Nuki est a 220 en promo mais il faut ajouter la Keypad hors de prix et qui n'a même pas de touche zero ce qui est parfaitement ridicule. - La plaque en métal qui s'installe sur la serrure alors qu'elle est en plastique sur le Nuki. La serrure est bien plus lourde que la Nuki. - La puissance du moteur qui semble bien plus costaud et qui ouvre plus rapidement la porte que la Nuki. - La possibilité de régler la vitesse de verouillage et donc de diminuer le bruit. Trois paramètres, normal, silencieux et mute, je préconise silencieux qui est le meilleur compromis vitesse bruit. Le mode mute peut être programmé pour se déclencher à une certaine plage horaire par exemple et ouvre la serrure très lentement et presque sans bruit. - Implémentation parfaite et simple de Apple Homekey (nécessite un hub thread Apple), possibilité d'ouvrir la porte très rapidement avec le télephone ou l'Apple Watch. Penser à activer le mode express sur Apple Wallet pour ouvrir la porte sans avoir à FaceID ou double cliquer sur l'Apple Watch. - Les nombreux adaptateurs inclus pour ceux qui ont des fermetures à bouton et des mousses de padding pour les personnes dont la serrure à juste une forme ronde afin que ca tienne bien en place. Sur la Nuki il n'y a rien de tout cela. - Le design sobre. - La stabilité de la connexion Thread Matter avec Homekit, là où ma Nuki se deconnectait du réseau très régulièrement. - La possibilité de se passer complètement de l'application Aqara pour l'installation (voir les restrictions ci-dessous) alors que pour la Nuki l'application reste obligatoire pour activer Matter, ajouter les Fob etc et la facilité de suppression du compte Aqara directement depuis l'app pour les maniaques de la confidentialité. - La calibration flash express qui se fait en un seul bouton et sans app, pertubant car on se dit c'est tout? - La fiabilité du Keypad qui fonctionne instantanément à tous les coups (vs les fob et keypad Nuki incroyablement capricieux et j'insiste, hors de prix) et qui offre en plus la possibilité d'etre cablé ou de fonctionner sur pile Les points faibles: - Nombreux bugs à l'installation!! Une fois les bugs contournés ca marche du tonnerre mais il faut comprendre que la serrure ne peut être installée soit en mode Aqara soit en mode Homekit! Et il me semble que c'est indiquée nul part. Pour ma part j'ai installé dans un premier temps en Homekit puis reset car je n'ai pas tous les paramétrages souhaités dans l'app qui demande de créer un compte pour y acceder, une fois la serrure paramétrée et mise à jour,j'ai supprime la serrure de l'app pour enfin la remettre en mode homekit. Vous allez vous arrachez les cheveux sur le bug du bluetooth qui ne communique pas sinon. - Pour les personnes qui ont une porte sans poignée extérieure, il faut donc dans un premier temps créer le compte Aqara, ajouter la serrure dans l'app, la mettre à jour avec le tout dernier firmware et activer la fonction de retractation du ressort pour qu'à chaque déverouillage sur Homekit la porte se déverouille à fond. Il s'agit pour le moment d'une limitation Apple qui n'a pas encore implémenté la derniere version de Matter et qui ne fait donc pas encore la différence entre déverouiller et ouvrir la porte car les serrure sans poignée n'existe pas aux USA. Les dernières versions de Matter avec implémentation de ce type de serrure sont bien prévu pour les prochaines mise à jour iOS 18, le problème n'est donc que temporaire. - L'impossibilité d'ajouter les empreintes digitales sans l'application ou alors c'est indiqué nul part comment faire mais je n'ai pas spécialement cherché. Ce qui n'a pas été testé : - La reconnaissance des empreintes digitales, car la possibilité d'ouvrir la porte avec le téléphone ou un code rend cette fonctionnalité bienvenue mais superflue. Pour résumer, un modèle très nettement supérieur au concurrent, qui n'a plus aucune raison d'être sauf si la personne a déjà investi considérablement dans l'ecosysteme Nuki.

Ich habe schon lange auf das Aqara U200 Türschloss gewartet und es jetzt endlich vor kurzem gekauft. Die Installation war sehr einfach und problemlos. Einfach den Montagerahmen mit den drei Schrauben am Türschloss, das etwa 3 mm heraussteht, befestigen. Danach den Schlüssel von innen stecken und die Motoreinheit daraufsetzen. Diese wird dann mit drei Schrauben am Montagerahmen befestigt. Anfangs hatte ich Bedenken, ob das so halten wird, aber es hält bombenfest. Das Keypad habe ich bei der Installation zunächst nicht montiert da ich erstmal testen wollte wie es funktioniert. Um die Einrichtung zu beginnen musste nur noch der Akku und die vier AAA-Batterien eingelegt werden. Danach habe ich mir die Aqara-App heruntergeladen und einen Account angelegt. Das Hinzufügen des Geräts ist kinderleicht. Einfach den QR-Code einscannen, und man wird Schritt für Schritt in der App weitergeleitet. Nach der Installation habe ich das Türschloss getestet. Hier muss in der Aqara-App eingestellt werden, dass sich die Falle öffnet. Wie lange die Falle geöffnet sein soll, kann in Sekunden eingestellt werden. Das Türschloss funktioniert äußerst zuverlässig. Besonders beeindruckend ist der Fingersensor, der extrem schnell reagiert. Ich würde sagen, dass es nur etwa eine halbe Sekunde dauert – echt Wahnsinn. Wird der Fingerabdruck als richtig erkannt, leuchtet die kleine weiße LED am Keypad auf und die Tür wird geöffnet. Wird ein falscher Finger aufgelegt, leuchtet die LED rot. Da bei mir alles über Apple Home läuft, wurde das Aqara U200 gleich in Apple Home hinzugefügt. Hier einfach den Matter-Code Einscannen. Bei der Einrichtung wurde mir auch gleich der Vorschlag gemacht, den Homekey in das Wallet hinzuzufügen. Dies habe ich auch sofort gemacht. Auch hier kann ich sagen, dass es extrem schnell und zuverlässig funktioniert. Hier gibt es die Möglichkeit, das iPhone ohne Entsperren und ohne Face-ID aufzulegen, und das Schloss öffnet sofort. Diese Funktion kann man in der Wallet-App von Apple einstellen. Diese nennt sich Expressmodus. Ohne Expressmodus muss der Homekey-Zugang jedes Mal mit Face-ID bestätigt werden. Dies ist natürlich sicherer, dauert dann aber etwas länger. Selbstverständlich kann das Schloss auch mit einem Zugangscode, der mindestens sechsstellig sein muss, entriegelt werden. Auch das funktioniert problemlos. Sollte der Akku leer sein, kann die Haustür ganz normal mit dem Schlüssel geöffnet werden. Für den Preis bietet das Aqara U200 eine top Qualität. Obwohl das Gehäuse aus Plastik besteht, ist die Verarbeitung klasse. Der Fingersensor ist definitiv das Highlight dieses Produkts. Ich nutze ihn fast ausschließlich, da er so schnell und zuverlässig funktioniert. Ein kleiner Nachteil ist, dass sehr kleine Kinderfinger oft nicht richtig erkannt werden, da sie zu klein für den Fingersensor sind und diesen nicht vollständig abdecken. Dies habe ich aber schon bei der Einrichtung festgestellt. Der Sensor sollte nach Möglichkeit komplett mit dem Finger abgedeckt sein. Ich würde sagen, dass es für Kinder unter vier Jahren nur bedingt möglich ist. Fazit: Insgesamt bin ich begeistert von dem Aqara U200. Ich kann dieses Türschloss definitiv weiterempfehlen!

Very impressed with the product. Is my 6th different smart lock, installation was a breeze. Love that the keypad can be separate from the exterior door - makes for a very clean, standard look. Apple home and Aqara user already so found set up very easy. All the Apple HomeKey features work perfectly. The only thing family doesn’t like is the manual turn to unlock inside is very stiff. Have not quite worked out why but everything else is working perfectly and very stable in HomeKit so I’m not bothered by it.
