Aqara Smart Lock U200 Review

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I have been a big fan of smart locks for several years. Back in 2019 I reviewed the Yale Conexis L1 Smart Lock and the Nuki Smart Lock 2.0 and at the time they were about the only half decent options you could get.

Since then, the market has become much more competitive but there still are not many great options out there.

One common concern is smart locks that don’t accept a mechanical key as a backup could potentially lock you out of your home. I almost had this problem with the We.lock Smart Lock on my garage door the other day. It didn’t accept my PIN code, and I was struggling to log in to the app to unlock it. I sorted it eventually, but it did trigger my anxiety about the potential of an expensive locksmith callout.

In recent years, many brands have developed locks that factor in this concern. The Nuki wasn’t the first lock I tried that effectively worked as a smart key turner, and a couple of years later, I committed to using the Yale Linus on my front door full time, and I also have the Ultion Smart Lock in my back door which is based on Danalock.

Recently, Aqara launched their Smart Lock U200 on Kickstarter and has now launched this globally.

It works just like Nuki, Ultion and the Yale Linus. The device basically sits on top of where your key sticks out and it automatically turns the lock for you.

The Aqara Smart Lock U200 has some nice additional features:

  • It is one of the few smart locks with Matter, and it is the only smart lock that I am aware of that uses Thread.
  • Because it uses Matter over Thread, you don’t have to use an Aqara hub or the Aqara app to use the lock.
  • A keypad is included as standard, and this includes a fingerprint scanner.
  • It integrates with the Aqara ecosystem which is significantly larger than any other brands. For example, it can work with the Video Doorbell G4, when someone presses the doorbell, you can view the notification in the Aqara app and unlock the door.

Unboxing / Design

Aqara Smart Lock U200 Unboxing

The U200 consists of two main components: the lock mechanism that replaces your existing internal lock, and an external keypad. Both parts are available in silver or black finishes, offering a sleek and modern aesthetic that should complement most door styles.

The lock’s design is minimalist and unobtrusive. The keypad features a fingerprint sensor and backlit buttons, providing easy visibility in low-light conditions. The tactile, rubbery buttons offer a satisfying feel when pressed.

Physical Installation

Aqara Smart Lock U200 Installation Backplate

Installation is straightforward for those with basic DIY skills. Aqara provides detailed instructions, guiding users through the process step-by-step.

One potential drawback is that some users may need additional tools for installation, depending on their existing lock setup. The manual calibration process also requires the lock to be cycled twice, which might be a minor inconvenience during setup.

Aqara Smart Lock U200 Installation Main lock

For my installation I was able to reuse the Yale adjustable cylinder I had installed.

As I am from the UK, I have a euro cylinder with a mutli-point locking system which requires you to push up the handle to engage the lock.

Aqara Smart Lock U200 Installation Battery

Just like the Yale Linus, the mounting bracket sits on top of the door handle hardware. It is partially held into place with 3M tape and there are then some tiny screws embedded into the backplate which you tighten up against the cylinder.

The main lock it then fixed to the backplate using screws that go into the prongs that stick out of the backplate. The end result is that the lock stays firmly in place.

Set Up with Aqara Home and Calibration

The initial set-up with the Aqara app pairs the lock using Bluetooth, and you can use the lock perfectly fine like this, but you won’t be able to control it remotely, and some advanced features may be missing.

Initial Pairing

To begin the setup process:

  1. Download and install the Aqara Home app from your device’s app store.
  2. Create an Aqara account if you don’t already have one.
  3. Ensure your smartphone’s Bluetooth is turned on.
  4. In the app, tap the “+” icon to add a new device.
  5. Select “Smart Lock U200” from the list of available devices.
  6. Follow the on-screen instructions to put the lock into pairing mode.

The lock should automatically enter pairing mode for 10 minutes after installing the battery. If this window has passed, you can manually activate pairing mode by pressing and holding the reset button on the lock for 5 seconds until you hear a beep.

Lock Calibration

Calibrating the lock is essential for ensuring smooth operation and accurate status reporting. The U200 offers two calibration methods:

  1. Automatic Calibration:
    • In the Aqara app, go to “Settings” > “Calibrate Lock”.
    • Choose “Automatic Calibration”.
    • The lock will automatically determine its locked and unlocked positions.
  2. Manual Calibration:
    • Go to “Settings” > “Calibrate Lock” in the app.
    • Select “Manual Calibration”.
    • Follow the app’s prompts to manually set the locked and unlocked positions.

The manual calibration option is particularly useful if the automatic process doesn’t yield satisfactory results or if you want more precise control over the lock’s operation.

Configuring Basic Settings

After pairing and calibration, you can configure various settings in the Aqara app:

  1. Lock Name: Assign a unique name to your lock for easy identification.
  2. Auto-Lock: Set the time delay for automatic locking after the door is closed.
  3. Notifications: Configure alerts for low battery, unauthorised access attempts, or when the door is left unlocked.
  4. Operation Mode: Choose between Normal and Silent modes depending on your preference for audible feedback.

Pairing with Aqara Hub M3 using Matter over Thread

I am not sure I am cured when it comes to Matter or if Matter has a lot of teething problems.

Similar to all my other reviews of Matter-based products, I had a nightmare pairing this up with the Aqara Hub M3.

Just like other reviews, I would put it into pairing mode, and it would time out.

  • The first mistake I was making was when it says to press the set button, it is a single press. Don’t hold the button. It is a little confusing because normally when you put something into pairing it will notify you it is in pairing, this did not.
  • You need IPV6 enabled on your router (mine already was).
  • One common issue/solution is that you need the hub, device, and phone to be all close by as it uses Bluetooth for onboarding. Thankfully, as the Hub M3 uses POE, I was able to temporarily run a long Ethernet cable to near where the lock was, but that didn’t seem to help.
  • Some people have suggested making sure any other Thread Border Router is powered down to make sure there are no issues (though this shouldn’t be a problem at all, Thread Border Routers should talk to each other, that’s the whole point).
  • Finally, one solution was to pop the battery out after you calibrate the lock. When you scan the Matter code, pop it back in.
    • This almost worked immediately. The Aqara app identified and connected to the device but failed on network connectivity.I retried multiple times, and in subsequent attempts, I didn’t need to pop the battery out.
    • Finally, I switched to my Honor Magic6 Pro to try and rule out my Samsung Galaxy S24 Ultra. I still had issues but on the third attempt it works.

I can’t say for sure what worked and what didn’t, popping the battery out definitely made something happen and from there you just need to be patient and keep retrying.

It has also been suggested that binding to the M3 could have been a firmware issue and this may be fixed now. I didn’t upgrade the firmware before trying to bind, which, in hindsight, was a bit stupid.

Keypad Set Up with Passcode, Fingerprints, and NFC Tags

The Aqara Smart Lock U200’s keypad is a central feature, offering multiple access methods. Setting up these various entry options is generally straightforward, though it does require some time investment to fully configure.

Passcode Setup

The U200 supports up to 100 unique passcodes, providing ample flexibility for different users or scenarios. To set up a passcode:

  1. Open the Aqara Home app and select the U200 lock.
  2. Navigate to the ‘Access’ section.
  3. Choose ‘Add Passcode’ and follow the prompts.
  4. You can set passcodes as permanent, temporary, or one-time use.
  5. For added security, passcodes must be 6-10 digits long.

The process is intuitive, and the app guides you through each step. You can also set schedules for when certain passcodes are active, which is useful for restricting access for household staff or short-term guests.

One minor drawback is that you can’t set custom names for passcodes within the app, which might make managing multiple codes slightly less convenient.

Fingerprint Registration

The U200 can store up to 50 fingerprints. The fingerprint sensor is located at the top of the keypad, making it easily accessible. To register a fingerprint:

  1. In the Aqara Home app, go to the ‘Access’ section of the U200 lock.
  2. Select ‘Add Fingerprint’.
  3. Follow the on-screen instructions, which typically involve placing your finger on the sensor multiple times from different angles.

The registration process is thorough, requiring several scans to ensure accurate recognition. This attention to detail pays off in daily use, as the fingerprint sensor proves to be reliable and quick to respond.

Users report that the sensor works well even with slightly damp or dirty fingers, which is a significant advantage for a device used outdoors.

NFC Tag Configuration

The U200 supports NFC tags for contactless entry, which can be a convenient option for users who prefer not to memorise codes or use their smartphones. To set up an NFC tag:

  1. In the Aqara Home app, navigate to the ‘Access’ section of the U200.
  2. Choose ‘Add NFC Card’.
  3. Hold the NFC tag close to the lock when prompted.
  4. Name the tag in the app for easy management.

The lock doesn’t support most standard NFC tags. Using an Aqara NFC tag is your best bet but others have said that the Mifare NFC tags that are available on Amazon will work.

General Keypad Usage

The keypad’s backlit buttons activate when touched, making it easy to use in low-light conditions. The buttons have a satisfying tactile feel, providing clear feedback when pressed.

One potential issue is the keypad’s size. While its compact design contributes to the lock’s sleek appearance, users with larger fingers might find it slightly cramped.

The keypad also features a privacy mode, activated by pressing and holding the lock button. This temporarily disables all electronic access methods, providing an extra layer of security when needed.

Third-Party Integration – Home Assistant

The U200’s support for Matter over Thread is a standout feature. This allows for seamless integration with major smart home platforms, including Apple HomeKit, Amazon Alexa, and Google Home. The lock can be controlled through these platforms’ respective apps and voice assistants.

For Apple users, the HomeKey feature is a significant draw. The ability to unlock your door with a simple tap of your iPhone or Apple Watch adds a layer of convenience that many will appreciate. It’s worth noting that HomeKey requires an Apple home hub (HomePod, HomePod mini, or Apple TV) to function.

The Aqara Home app provides additional functionality and customisation options. Users can manage access codes, view activity logs, and adjust various settings through the app. While the app is generally user-friendly, some users might find the interface a bit cluttered due to the wealth of options available.

Security

Security is paramount for any smart lock, and the U200 doesn’t disappoint. The lock uses AES-128 encryption for its wireless communications, providing robust protection against potential hacking attempts.

The ability to create temporary access codes adds an extra layer of security and convenience. You can provide time-limited access to guests or service providers without compromising your main access methods.

The auto-lock feature and low battery alerts help prevent situations where your door might be left unsecured. The activity log also allows you to monitor who has accessed your door and when, adding an extra layer of security awareness.

In Use

Unlocking Performance (Passcode / NFC tag / Bluetooth / Remote / Temporary Passcode)

In day-to-day use, the U200 performs reliably across its various functions. The fingerprint sensor is particularly noteworthy, offering quick and accurate recognition even with slightly dirty fingers – a common issue with some other smart locks.

The lock’s response time is generally fast, whether using the fingerprint sensor, passcode, or HomeKey. Coming from the Yale Linus, this has been a big improvement. The Yale app was awful, and the keypad wasn’t great, so I found that I used my physical key most of the time as it was quicker. That is not the case with the Aqara, it is much faster just to scan my fingerprint.

Thread connectivity provides a stable and responsive connection to smart home systems. This is a significant advantage over Wi-Fi-based locks, as they consume less power and offer better range and reliability.

Battery life is impressive, with Aqara claiming up to six months of use and an average of eight daily operations. Real-world usage may vary, but most users should find the battery life more than adequate.

The auto-lock feature works as expected, but it has limited functionality in the UK. If you can remember to lift the handle to engage the multi-point locks, then you generally remember to lock the door. If you forget to lift the handle to engage the lock, the auto-lock will not work.

The quiet mode is also effective, reducing operational noise significantly.

Battery Life / Recharging

One of my concerns with the Aqara Smart Lock U200 is that it is only reported to have a 6-month battery life. Most competing options I have tried have a 12 month battery life. During my testing, it won’t last 6-mont, but I was using it much more than average.

Aqara claims this is based on performance based on up to 8 daily unlocking and locking actions via fingerprint/NFC, so I expect I would get longer.

One saving grace is that the smart lock itself uses a rechargeable battery and Aqara have thoughtfully designed it so you can charge the lock without removing the battery. The USB-C port is exposed when you remove the front panel, and they provide a little carry case which allows you to charge the lock using a power bank hanging from the door handle.

It is a bit of an odd way to do things, but it is much better than having to remove the battery from the lock until it is charged.

Price and Alternative Options

The Aqara Smart Lock U200 is available directly from Aqara for £279. This option includes a replaceable front panel in wood effect, an NFC tag and an AA battery adaptor.

It is then available from Amazon for £270 without those additions.

It is worth noting that while the Aqara includes a keypad, you will need an Aqara M3 hub or other Matter-equipped Thread Border Router to use it remotely.

There are a lot of competing options nowadays. Almost all the options lack a keypad, but some have the option to buy one, and many lack Matter/Thread for easy integration with third-party ecosystems

  • SwitchBot Smart Lock Pro + Touch pad
    • £240
    • When paired with Hub 2 it will support matter.
  • Nuki Smart Lock Pro (4th generation)
    • £245
    • Uses WiFi and works with Matter. Lacks a keypad but you can buy one for £145.
  • Nuki Smart Lock (4th generation)
    • £170
    • The same as the Pro but lacks WiFi or the Nuki Power Pack
  • WELOCK Smart Fingerprint Door Lock
    • £179
    • Lacks the option to use your key, no keypad on this model, WiFI bridge sold separately.
  • Yale Linus Smart Lock Bundle
    • £260
    • The bundle includes a WiFi bridge and keypad. I have personally used this the past couple fo years and it has worked well, my partner hates the app (on iPhone).

Verdict

I have mostly been happy with my Yale Linus smart lock so there was some reluctance swapping it out with the Aqara.

I had some teething issues setting it up but once it was working it has performed flawlessly.

And, I had some concerns about the £270 price tag. However, after looking at the competing options it is a similar price point as other options when you factor in the keypad. You can pick up the Yale Linus for just £120 for the lock itself, but the WiFi bridge is £50 and the keypad is £45.

Minor issues aside, I have been very happy with the Aqara Smart Lock U200. More importantly, my partner has been happy with it too. The keypad and fingerprint scanner have worked perfectly for her, and it is a big improvement over the Yale app.

Its support for Matter over Thread and Apple HomeKey sets it apart from many competitors, providing excellent smart home integration and convenience.

For people seeking a feature-rich, highly integrated smart lock – particularly those in the Apple ecosystem who want HomeKey support, or existing Aqara users, the Aqara Smart Lock U200 is an excellent choice.
