Review: 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.
Review: Work Well Feels Solid/Premium.. Pairing to the Aqara M3 Hub Thread over Matter was a little Gimmicky.

## 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 S***E on 16 November 2024*

These are the most reliable finger print door lock I have ever used in a residential application. The read speed and accuracy is the fastest I've ever experienced. Having the NFC unlock option via HomeKit is also great for if you're wearing gloves. The installation and setup instructions are via a very simple Youtube video, which is also straightforward. The only challenge I ran into is that it steers you into believing you need a Aqara hub for Homekit control; This is not the case. Once the device is setup in the app, open the Apple Home app and manually add the device using the QR Code. It will add quickly and pairs reliably.
