Review: Todo perfecto - Todo ha sido perfecto: el envío, el producto y la entrega se ha realizado antes de lo previsto. Review: You get what you pay for, so far it's a decent lock - I used to have different locks on desertcart which died after 6 months and I decided to go with more well-known brand. If you have any existing locks, it's very easy to install. I only use Fingerprint to unlock the door and so far, this is the smoothest lock that I ever had. Few downsides which don't reflect for me to degrade my rating. 1. For additional features, you absolutely need Aqara hub, or things that support matter over thread like Echo. If you have no hub, you cannot unlock from remotely and many missing features. I Will update my review when I get the hub. 2. Tha hassle part was setting up a connection via app. it seems like Canada is not an officially supported device so to find U300 on Aqara app, I had to switch to a different country. 3. It's only supporting with Aqara NFC tag. Even though I couldn't test more features as I'm only able to connect through Bluetooth, this is so far the best lock that I have and it's worth its price. ## 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. This flexibility allows seamless integration into a variety of smart home setups for enhanced automations and convenience. - 【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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D496H9YV | | Additional Features | Fingerprint | | Best Sellers Rank | #13,574 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #39 in Home Security & Surveillance Biometrics | | Brand | Aqara | | Brand Name | Aqara | | Color | Black | | Connectivity Protocol | Thread | | Control Method | Touch | | Controller Type | Apple HomeKit | | Country of Publication | China | | Customer Reviews | 3.8 out of 5 stars 365 Reviews | | Finish Types | Painted | | Included Components | Smart lock unit, Mounting hardware, USB-C cable (for backup power) | | Item Dimensions | 14 x 7.6 x 7.1 centimeters | | Item Weight | 2.5 Kilograms | | Item dimensions L x W x H | 14 x 7.6 x 7.1 centimeters | | Lock Type | Biometric, Keypad | | Lock type | Biometric , Keypad | | Manufacturer | Lumi United Technology Co., Ltd | | Manufacturer Part Number | AD030USG02 | | Manufacturer Warranty Description | 6 months | | Material | Zinc | | Material Type | Zinc | | Model Name | U300 | | Model Number | DL-D02D | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Recommended Uses For Product | doors | | Recommended uses for product | doors | | Shape | Rectangular | | Special features | Fingerprint | | Style Name | Contemporary | | UPC | 192784001639 | | Unit Count | 1 Count | ## Product Details - **Brand:** Aqara - **Item dimensions L x W x H:** 14 x 7.6 x 7.1 centimeters - **Lock type:** Biometric, Keypad - **Material:** Zinc - **Special features:** Fingerprint ## Images ![Smart Lock U300, Fingerprint Keyless Entry Door Lock with Handle, Matter Over Thread with Apple Home Keys, Touchscreen Keypad, Smart Lever Lock Supports Apple Home, Alexa, Google, IFTTT, Black - Image 1](https://m.media-amazon.com/images/I/71wkjlwHvEL.jpg) ## Questions & Answers **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 hub for network integration. Note: Each hub works only with its own app. Example: Apple Home Key requires the Home app and Apple hubs. **Q: Why can't my U300 pair with the app (non-Aqara app)?** A: Check the following: • Use a Matter-over-Thread hub; • Enable IPv6 on your Wi-Fi; • Phone and hub on the same Wi-Fi; • Bluetooth turned on; • Lock within 5 m of the hub with no obstruction; • Press the Set button before pairing; **Q: Can the handle of the Aqara U300 be reversed?** A: Yes, the handle can be reversed. Please watch our instructional video carefully before attempting, as incorrect installation may cause a loose handle or affect certain functions. **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: 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). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Todo perfecto *by A***Z on 2 February 2026* Todo ha sido perfecto: el envío, el producto y la entrega se ha realizado antes de lo previsto. ### ⭐⭐⭐⭐⭐ You get what you pay for, so far it's a decent lock *by K***M on 17 October 2024* I used to have different locks on Amazon which died after 6 months and I decided to go with more well-known brand.
