U200 fails to calibrate

Hello, I have installed a new U200, configured for US deadbolt operation. The unit fails to calibrate. You can hear the motors grinding but the mechanism to move the deadbolt does not spin. It is like a clutch not engaging. Have tried all variations of Quiet mode, factory resetting, calibration from the lock and from the Aqara app. Tried using the Aqara AI chat and now just getting a server busy message. Any suggestions? Does Aqara have an actual support desk? Thanks

@dale_poloway I’m sorry to hear you’re experiencing issues with the calibration of your Smart Door Lock U200. It sounds like you’ve tried several troubleshooting steps already. Here are a few more suggestions that might help resolve the problem:

  1. Check Mounting Screws: Ensure the mounting screws are neither too loose nor too tight, as this can affect the lock’s calibration.

  2. Re-attempt Calibration:

    • Close the door and unlock it from the inside.
    • Press and hold the Set button on the lock for 3 seconds to initiate calibration. If the lock beeps twice, it indicates calibration failure.

  3. Use the Aqara Home App: Try the manual calibration feature in the Aqara Home app by navigating to “Settings” > “Calibrate Lock.”

  4. Firmware Update: In the app, go to profile > firmware update, enable beta updates, and upgrade the device to the latest version. Then attempt calibration again.

  5. Switch Lock Mode: In the settings under Lock Mode, switch the mode to “Standard” and attempt calibration again.

  6. Manual Intervention: If it still fails, try inserting the key and, during the final half-turn of the calibration, block the U200 to prevent it from turning further and see if it succeeds.

If these steps don’t resolve the issue, please contact Customer Service Team by the Aqara Home App (Profile>Help&Feedback>Customer Service) or scanning the QR code:

I have the exact same problems as the friend above. I was using it in European mode. Now I can’t use the lock. It was working fine before the v80 update. The assembly is the same assembly. No changes. But after the v80 update, the lock went crazy. It can’t calibrate. There is a constant sound like gear scraping. Sometimes I say unlock, it closes or vice versa. When I say pull the bead, it locks. However, most of the time there is a sound like gear scraping and it doesn’t do anything. I think it needs to be fixed urgently with the new update. Or please give me the opportunity to go back to the previous version. Best regards.

Hi Can you please provide a video of the calibration? We can ask developer to determine the cause first, thanks!

Hi Yusuf, did you ever resolve this issue with your U200 lock? I was unable to get it resolved and ended up returning all 3 locks that I purchased.

I have the exact same problem after installing the U200. Firmware has been updated. The lock makes noise but does not turn the bolt at all.
Maybe it is best to just return the item and get a different brand lock?
I created a ticket with Aqara but have not heard anything back yet. It would be great to talk to a human.

Same problem here … really hope there is a fix soon.
The lock is unuseable at the moment

Exactly same problem. I tried everything but to no avail. How is this not a top priority for Aqara at the moment?? The lock is practically unusable

Experiencing the exact same issue… on top of the Homekey failure described in another topic. Would be nice if @AqaraOfficial would at least reply with a confirmation if this is indeed a firmware issue that will be resolved shortly, or if we should indeed start checking if our warranty is still valid.

Exactly the same issue, fails to calibrate, started with failing to unlock, I hear gears spinning but clutch is not activating, or whatever causes the key not to rotate. It’s infuriating honestly, Anyone managed to revert to an older firmware or something, it is unusable and I’m out of the amazon return window.

I think this is the gearbox issues that some U200 have.
I personally have 2 U200 - one Kickstarter - working perfectly.
one bought from local reseller - started having the issue recently - now I am trying to replace it under warranty.
here is a video of the defective one: https://photos.app.goo.gl/VXweyaW1a1bSPoSG7

I have the same issue. Aqara sent me a new u200 lock. I tried to auto-calibrate it with the factory installed firmware and it started correctly. But my door was misaligned and it failed. I fixed the alignment, but before I recalibrated it, I saw there was a newer firmware (v77) and I upgraded. Then I tried to auto-calibrate and it doesn’t not work. It beeps a bunch and I can hear the internal gears turning, but the knob and deadbolt do not budge (even with the door wide open).

I don’t think this is a hardware issue. It’s software related. I regret upgrading the firmware. Seems I have another bricked u200 lock.

Exactly the same problem here. I did every firmware update and everything worked well, but I had to move the device to another door.

Calibration failed due to the same problems described here.

Naturally, i assumed I did something wrong during the hardware installation and spend hours troubleshooting.

Glad to read it’s probably a software issue. But, Aqara… get it fixed!

My U200 that had issues is even worse now - the cylinder barely moves - the lock is defective this is sure!
It is under warranty but it is bought from a web store (emag.bg) that sells stuff from other sellers. The seller do not respond to my questions and queries.
Any idea if I can ask Aqara for support directly?

I’ve contacted Aqara an received a replacement device, because I still had warrenty (bought last year in September). You should ask for this as well.

Anyhow, I don’t understand why this cannot be fixed via a firmware update.

@Aqara, any comment? Is there a certain batch of locks which is damaged beyond repair after updating the firmware to v x.077?
