Description

As a leading provider of smart home solutions, Aqara excels in delivering a wide array of award-winning, user-friendly smart home products and platform solutions tailored for your home. We proudly serve over 12 million customers in more than 170 countries and territories. Our products are designed to offer convenience, security, and energy efficiency, making your home smarter, more sustainable, and adaptive to your evolving needs. Is this a Wi-Fi-enabled smart lock? 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. Why can't my U300 pair with the app (non-Aqara app)? 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; Can the handle of the Aqara U300 be reversed? 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. How do I know if this will fit my door? 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. Can the Aqara U300 be used on outdoor doors? 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).

    • Great smart lock that's HomeKit friendly
Color: Black

Review Image by Michael Templin
Quality build of this product is very good. Was wanting a smart lock going from garage into house and I kept looking at this one and finally decided to purchase it. Received the item very quickly. Price could be better, there are cheaper ones out there but I wanted one that would connect to HomeKit and reviews on Aqara were positive. Install is straight forward, but they have an install video online if you need to reference which is nice. Out of box the handles were opposite of what I needed but changing them was very easy. Connecting to the Aqara app was very easy but if you are wanting to use all the features you will need a hub. Connecting to HomeKit was very easy with Matter. Finger print scanner is hit and miss with me but my fiancé has no issues must just be me, LOL. I use my Apple Watch with home key to unlock which is very slick and nice. All in all solid smart lock with great features. ... show more

    • Best smart lock
Color: Silver
A phenomenal smart lock for interior doors, this was super easy to install, and works like a charm. The HomeKit compatibility is great but the functionalities really shine within the Aqara app, and high adds many great features. The fingerprint unlock is super helpful, the lock is extremely reliable, the only one that has never left me stranded outside, and I tested many over the years. The only complaint I have, and I may be crazy, is that it just doesn’t feel super sturdy, not even sure if that’s the right word, but it just feels so light to the touch… it looks incredible though and for the price point, you can’t beat it! ... show more

    • Problems Problems and more Problems
Color: Black
I have paired this lock to my matter/thread system 4X and still I have yet to get it to respond to commands from the app without Bluetooth. It will not remotely unlock or lock unless I keep the keypad alive. Also even without anyone using the lock the batteries only last 2 days. I have replaced them 5 times in 2 weeks with different brands. Something is draining the power. Commands only work one way, meaning if you unlock with your finger or code it instantly shows up with the state change on the phone, try going the other direction and nothing…unless you keep the keypad lit. I have a M200 hub and nothing. Waiting for the company to respond (which they have) but the return period is closing so it may get sent back! I will follow up with how it ends. ... show more

    • Well built, secure lock with safety first!
Color: Black
It was easy to install, there are eight ways to unlock the U300 (includes Apple Home) but I only use four. Gives off signal if lock is tampered with. Additional people can be added to Smart Lock making it easy for visitors to use. Lock is safer than having a dead bolt along with separate door handle. Many more features that are not listing ..just go on line to find than all! I’m happy with Smart Lovk U300 & highly recommend this lock. ... show more

    • Awesome, but here’s the thing…
Color: Silver
Perfect? No, but really good and no regrets. HomeKit- I use HomeKit to connect with it. It paired super easy, works great. However, HomeKit means I have to confirm I want it to unlock or lock when leaving and coming. So it’s a tap of a watch, not a big deal. Not this company’s fault either. Fingerprint- spoiled by phones it’s not a single hit each time. Generally it’s fine though. Sometimes once, sometimes a few times of my hands are a little grimy. Not had to use it often, but sometimes I walk out and forget my phone to unlock it. So it’s cool to have multiple options. Keypad- yeah, works perfect lol. Additional goodies - I love, LOVE that I can set a profile up for someone to use fingerprint to let them in, but reserve the option to delete it without having to worry about a key or changing the keypad number. Just delete their profile and done lol. Second is notifications of locking. It’s a little thing, but that extra security makes me feel better. Calibrating to your door, which I didn’t expect. My door closes firm and securely where it never really did before. Not sure what black magic happened to make it work perfectly, but there you go. Why 4 stars? Well, when you close the door, it’s super easy for your hand to hit the keypad and lock it behind you by accident. It is the sole thing that annoys me most about this that isn’t just HomeKit stuff. Am I advising you buy one? Yes, very worth it to skip deadbolts, built like a tank, good on batteries, easy to connect, no third party bloat really, and it’s been rock solid for months. ... show more

    • Very well made and love how easy it is to swap batteries
Color: Black
Update 5/26/26 - first lock started falling apart on day 25. Tried working with support but that was very slow, days between responses. I got to day 29 and pulled the trigger on an exchange so I didn’t lose my window. The lock handle got loose and I was asked to take apart the lock and tighten screws. I’m concerned that 25 days of daily use caused this. I’ll report back on the exchange and see if it holds up. Knocking off a star for now, but if it’s a fluke I’ll update it. Love the lock so far. Love how easy it is to change the batteries. Some of our smart handles are obnoxious with battery changes. I’ll happily trade off some aesthetics for function there. Connectivity is fantastic, no issues. Will be upgraded my other interior door handles to this also. ... show more

    • It is a great lock and works well with Home Assistant
Color: Black
I had a Eufy C33 on my front door. We had several issues with it: the keypad was dark, and you had to repeatedly hit the pad to get the numbers to show and the fingerprint detector did not work most of the time. I ordered the Aqara since it works with Matter, and I have Home Assistant currently running. Installation was a breeze. I even commented to my wife how there was no "Oh crap" moment that dragged out the install. I connected my to Home Assistant and integration was also straightforward. The keypad is easier to see, and the fingerprint reader has been 100% so far. I do like that it has a speaker, and there are some times where it will say something verbally which i think is good. Also, it only uses 4 batteries versus 8 for the C33. I like this lock, and will likely switch over my other doors to this. ... show more
