## 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.
