Review: I like Aqara but it requires hubs to maximize the features - The Aqara U300 works great! I really love the passcode, fingerprint, and Bluetooth access. My house is about 2,200 sq ft, and I’m able to control the lock via Bluetooth throughout the entire house without any issues. If you want NFC or Apple Wallet features, you do need to purchase an Aqara Hub, but overall the user interface and functionality are excellent. Installation was easy for me since my garage door already had a handle-style lock. It is definitely more expensive compared to other smart lock systems, but in my experience, it’s worth it. I previously used an August lock, and the connection was very inconsistent. The Aqara U300 feels much more reliable and polished in comparison.
Review: Loose exterior handle (received ANOTHER BAD lock from Aqara Customer Support) - UPDATE 2: Received and installed the replacement lock a few months back, and now the handle of the new lock is also becoming loose (it is about as loose as was the previous handle, just before it fell off.) There is nothing special about this door, or how the handle is used. I asked Aqara Support to review the issue with the engineering team. If the issue has been fixed, perhaps by simply using thread sealant on those tiny screws, I would be happy to try another handle but for now I unfortunately have to rate this product with one star. Aside from this issye it's a good lock, but this is a complete deal breaker. UPDATE 1: Aqara Customer Support did eventually respond to my concern with the loose exterior door handle. I imagine the issue described below still exists so bumped the review to four stars, hoping Aqara will after this issue and more securely attach the handle in a product update. ORIGINAL REVIEW: The exterior handle came loose about two months after installing and moderate use. Contacted Aqara support multiple times and received nothing but questions and irrelevant video links clearly meant to deter me from pursuing having the door handle repaired or replaced. After asking for a resolution, Aqara Support stopped responding altogether. I am very disappointed with the quality and lack of support. DO NOT BUY FROM THIS COMPANY. There are plenty of other great product from reputable businesses! The door handles look ok and I like the idea of Matter + Thread support, but it is not worth investing in a product that breaks and where no support if provided by the company.

## Features

- 【Apple Home and Home Keys Integration】The U300 is a smart door lock seamlessly integrated with Apple Home (requires an Apple 2-in-1 Matter Controller & Border Router). You can unlock it effortlessly using Apple Home Keys by simply tapping your iPhone or Apple Watch, even when your device is out of power. Additionally, door access can be easily managed and shared with guests directly through the Apple Home app.
- 【Smart Automations with Aqara and Third-Party Devices】When paired with an Aqara Thread-enabled Matter Hub (like the M3), the U300 supports smart home automations and remote unlocking. Thanks to the Matter over Thread protocol, it’s also compatible with third-party ecosystems such as Google Home, Alexa, IFTTT, and Samsung SmartThings. This flexibility allows seamless integration into a variety of smart home setups for enhanced automations and convenience.(Tips: After adding the door lock to the Aqara Home app, only the administrator's fingerprint or password can reset the door lock.)
- 【Multiple Unlocking Options Including Fingerprint】The U300 features multiple unlocking methods, including a highly accurate fingerprint reader on the handle, which supports up to 25 unique fingerprints. It also offers one-time local passwords for use and periodic passwords for guests when offline. It's worth reminding you that you can also unlock your door using your Aqara NFC card, which is a very convenient thing to do!(*Note: NFC card is sold separately.)
- 【Passage, Auto-Lock & Do Not Disturb Modes】The U300 offers two primary modes: Passage Mode, ideal for quick, hassle-free entry in high-traffic areas like commercial spaces or garages, and Auto-Lock Mode for enhanced security. Additionally, Do Not Disturb Mode mutes the lock's sounds during specific time frames, ensuring a quieter experience when coming home late without disturbing others.
- 【Durable, Secure & Long Battery Life】Built from robust zinc alloy and rated IPX4 for water resistance, the U300 is designed to withstand temperatures from -22°F to 131°F. Powered by 4 AA batteries, it boasts an impressive battery life of up to 10 months. In case of emergency, two USB-C ports are available for backup power. All sensitive data, including fingerprints, is stored locally with full AES encryption for maximum security.

## Questions & Answers

**Q: Can this product connect directly to HomeKit or other Matter-enabled ecosystems?**
A: No, the product requires a Matter controller to connect to any Matter-enabled ecosystem, including HomeKit. Please refer to the image above, which lists the required Matter controllers for each ecosystem.

**Q: Can the Aqara U300 be used on outdoor doors?**
A: We do not recommend exposing the product directly to rain or snow. If used outdoors, it must be installed under a covered entrance (e.g., a porch or awning).

**Q: Is this a Wi-Fi-enabled smart lock?**
A: No. It utilizes the Matter over Thread networking protocol and requires a compatible Matter-and-Thread-enabled smart hub for network integration.

**Q: How do I know if this will fit my door?**
A: The lock fits doors with a 2 3/8" or 2 3/4" (60–70mm) backset, 1 3/8"–2 11/64" (35–55mm) thickness, and a 2 1/8" (54mm) hole. If your door has two boreholes (typically for separate deadbolt and handle), a deadbolt-style lock may be more suitable.

**Q: What should I do if the mechanism doesn't turn?**
A: Please first confirm door compatibility, ensure the lock is installed straight and level, and make sure the strike plate is properly aligned and installed.

### ⭐⭐⭐⭐⭐ Just great. Really happy.
*by J***N on November 29, 2024*

We got a bunch of U100 and U200 locks previously and Aqara lying to us! The batteries last a lot longer than they say! And I pass through our doors a lot more often than the average person. And yes, I'm in a cold climate in both Detroit where we lived and now in the mountains of West Virginia. For the house in WV I ordered six of these and installed one to date. Did so right at the beginning on the cold. When I installed the lock it was 70º, sunny and beautiful. By the time we left it was 24º and the lock was crusted over in a thick layer of ice. Get this! The lock read my thumb print through the nice - no problem! And the keypad also worked brilliantly. I've got to say Aqara, at least with their lock products, seems to have an "under promise and over deliver" policy and I love it! I don't like to mention competing products in reviews but I've got to say: I removed our top-of-the-line Level Lock Plus in favor of an Aqara lock. They're more responsive, less troublesome, and far more trustworthy as devices go. You get the sense from their marketing that Level is the top of the heap but they're not. If you're running an Apple Home these are the ones you want. Turn on Express Passage and your door unlocks the first time you raise your device to it - every time, though you'll never use the feature with these as the thumb print is so much more convenient. I don't work for them. I didn't receive a test product. I'm just a really, really impressed and extremely happy customer. Aqara did it again with the U300. It's about as perfect as lock as you could hope for if you're needing a smart knob-replacement lock that truly supports your chosen ecosystem. Go on and buy with confidence. These things are dope. ❤️💋 Regarding some of the issues reported by users here and in other places: 1) Communication issues are likely environmental in my experience. Make sure you have an AppleTV, HomePod, or HomePod mini within 30ft of your lock. Make sure there's no brick and very little plaster and lathe between your lock and your HomeKit or Aqara hub. 2) Apple Home, HomeKey and other issues: Just remember you don't actually need the Aqara App if you're using HomeKit. It's a good idea to use the app so the lock is associated with you through their app and your account, but the app itself has nothing at all to do with HomeKit. In fact, anything you do through HomeKit is written to the lock separately. They're two different worlds and Aqara was wise to keep them separate. 3) If you're thinking about a smart lock have a look at your door first. If your closure is weird or unreliable, if after your close your door you notice there's a lot of pressure on the knob latch, or if your door frame has simply relinquished "square", this or any other smart lock is likely going to be problematic. Manual locks on doors that require fidgeting to make work are generally fine because they're manual. But those same doors are likely to introduce problems as most smart locks are made for new doors, or at least doors that close and rest properly. Be sure to assess your door first, If it has problems get those addressed BEFORE trying to install any smart lock. A bad closure will see your locks fail, not last, batteries may die faster...
