Review: Work Well Feels Solid/Premium.. Pairing to the Aqara M3 Hub Thread over Matter was a little Gimmicky.
Review: I like this lock mostly because there are very few smart options that aren’t deadbolts. The silver finish looks good and feels solid in the hand. It doesn’t feel cheap, but it’s also not on the level of a high-end decorative handle set. For me that’s fine, it fits in well with our foyer and doesn’t stand out in a bad way. Installation was straightforward. I followed an online video just to be sure I was doing it right, and everything needed was in the box. Adding it to the Aqara hub was simple, and then bringing it into Home Assistant via Matter and into Apple Home via Matter was also easy. Apple HomeKey works great on this lock. You also get multiple ways to unlock: physical key (included), NFC keycard (not included), Apple HomeKey, and Bluetooth through the Aqara app. Fingerprint unlocking is where things fall short. That was the main reason I bought this lock. The idea is you grab the handle naturally, it reads your thumb, and the door unlocks. The advertised 99% accuracy is nowhere near my experience. With just one thumb enrolled, it worked maybe 40% of the time. I ended up registering the same thumb as three separate fingerprints to try to capture different angles and grip positions. That bumped it up to around 75%, but that’s still not good enough. It definitely fails the “wife test” since she’s had to call me a few times because it wouldn’t unlock for her and I had to open it remotely. Battery life seems fine so far, but I’ll know more over a full year. In Home Assistant, you can see the firmware version, battery percentage and voltage, and tweak settings like how long the lock is disabled after failed attempts, which is nice. In short: it’s a good-looking, solid-feeling smart handle lock that fills a gap in the market and integrates well with Home Assistant and Apple Home via Matter. But if you need fingerprint unlocking to work almost every time, this version isn’t there yet. I’ll be watching to see if Aqara releases an updated model with better fingerprint accuracy before I buy another one for another door.

## 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 50 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: What are the door compatibility requirements for the Aqara U300 smart lock?**
A: The Aqara U300 requires a wooden door with a 2 3/8" or 2 3/4" (60-70mm) backset, 1 3/8" to 2 11/64" (35-55mm) thickness, and a 2 1/8" (54mm) hole diameter. Please double-check these measurements before purchase.

**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 (such as the Aqara M3 Hub) for network integration.

**Q: Why can't I connect my door lock to my hub or app?**
A: For Matter-over-Thread devices, ensure: 1) You are using an 2-in-1 Matter Controller & Thread Border Router 2) Your router supports IPv6 3) Your phone and hub are on the same local network during setup. If issues persist, restart your hub and router.

### ⭐⭐⭐⭐⭐ Review
*by D***N on 30 July 2025*

I bought 2 and although It can be a challenge to program these are the best and fastest fingerprint door locking handle on the market IMO. They can be setup and programmed via bluetooth prior to actually installing on the door, just pop the batteries in and using the ACARA app, create users and enter passcodes and fingerprints. Very study heavy duty door handle. Super fast. If that is all you want that's all you need to do. If you need to make changes or check your battery level you will have to be within 30' of the lock to be able to connect to it via the Acara app If you want remote functionality and notifications you'll need an Acara M3 hub to bridge these doorlocks to your wifi network. I have the Acara M3 hub and have connected and integrated it into my HomeAssistant server. This monitors my battery levels automatically and i can remotely control my locks all from my home assistant. Works awesome. I highly recommend this lock. I have 2 of them on my main house exterior door and my garage main door. Over 6 months of use and batteries are still at 90% under moderately heavy use.
