@rebin_ma I’m sorry to hear you’re having trouble with your Smart Door Lock U200. Here are a few troubleshooting steps you can try:

  1. Check for Physical Obstructions: Ensure there’s no interference between the connector cable and the cylinder tailpiece. Excessive friction or improper positioning can affect the lock’s functionality.

  2. Reposition the Mounting Plate: Make sure the tailpiece is centered in the deadbolt hole. Misalignment can lead to the issues you described.

  3. Battery Check: Confirm that the batteries are not depleted. If low, replace them with original or alkaline ones to avoid leakage and ensure optimal performance.

  4. Calibrate the Lock: Use the Aqara Home app to manually calibrate the lock under “Settings” > “Calibrate Lock” or try the local settings through the keypad.

  5. Firmware Update: In the app, go to Profile > Firmware Update, enable beta updates, and update to the latest version.

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

It might be famous aqara gear lubricant issue.
Will suggest to check gears sounds. @rebin_ma

I tried all of these, still the same. When it locks, the handle of the door lock gets so hard to even open it by hand. And it doesnt open by mobile or the finger print. May be this firmware version is the reason, how can I change it back to the old version of firmware?

@rebin_ma It seems you’ve already tried several troubleshooting steps without success, and you’re suspecting the firmware might be causing the issue with your Smart Door Lock U200. Unfortunately, the reference information I have does not include specific instructions on downgrading firmware to a previous version. Firmware updates are typically designed to improve functionality or security, and downgrading isn’t always supported as it could potentially introduce vulnerabilities or instability.

I recommend reaching out to Aqara’s Customer Service Team for more detailed assistance with your firmware concerns. You can contact them via the Aqara Home App by navigating to Profile > Help & Feedback > Customer Service, or you can create a ticket if you don’t have an Aqara Home account by clicking here.

I’m sorry I couldn’t provide a direct solution, but I hope the Customer Service Team will be able to help resolve your issue swiftly!

@rebin_ma what kind of lock door are you using, UK ,EU.
When you unlock :unlock: the door does the U200 spin and what does the status of lock shows in your aqara app. If status is unlocked, you can hear motor spin sound but does’t unlocked the door. It might be lubricant issue in that case you need to contact customer suppor.
