Aqara U200 won't calibrate and won't lock after firmware upgrade

The keypad prompted me to change the batteries. I did that, and while I was working with the lock, I saw that there was a firmware upgrade.

I did the upgrade. My lock now refuses to lock without being calibrated but it has failed calibration every single time the 12 (literally) times I’ve tried it.

The manual calibration selection says I have to do the automatic calibration.

Nothing changed about my configuration other than replacing the batteries in my keypad. I had been a very happy customer but this is really frustrating. My email to support has gone unacknowledged, not even an automatic response.

I’m on the latest version of firmware, so I can’t upgrade to a new one. There isn’t an option to use beta firmware that I can see. Nor can I go back to a previous version.

@jdeibele I’m sorry to hear about the trouble you’re experiencing with your Aqara U200 lock calibration. Here are a few steps you could try to resolve this issue:

  1. 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 a calibration failure.

  2. Manual Calibration via Aqara Home App: Go to “Settings” > “Calibrate Lock” in the app to attempt manual calibration. If the lock insists on automatic calibration, ensure that all steps for automatic calibration are followed precisely.

  3. Firmware Options: Although you mentioned not seeing an option for beta firmware, you may try going to the app under profile settings, enabling beta updates, and checking if a new firmware version becomes available.

  4. Adjust Mounting Screws: Ensure the mounting screws are not too loose or too tight, as this can affect calibration.

  5. Alternate Calibration Method: During the final half-turn of the calibration, try inserting the key and blocking the U200 to prevent further turning and see if this succeeds.
