Hi,

I have problem with my new SmartLock U200. I bought it from secondhand and it`s probably locked to user. Is there any reason how to delete account registration from this and use it on my own?
I have all receipts and papers about buying it.

Thank you very much

@info164 Hi Ondra,

Thank you for reaching out with your question about your secondhand Smart Lock U200. To reset the lock and clear the previous user’s data, you can follow these steps:

  1. For Aqara Home Users:

    • Press and hold the Lock and Confirm buttons on the keypad simultaneously for 3 seconds to enter Reset Mode.
    • After the prompt, verify with the admin password or fingerprint. If correct, the lock will clear all user data and restore factory settings.

  2. For Other Matter Ecosystem Users:

    • Press and hold the Lock and Confirm buttons on the keypad simultaneously for 3 seconds to enter Reset Mode.
    • After the prompt, press and hold the Reset button on the lock for 3 seconds. The lock will clear all user data and restore factory settings.

These instructions should help you reset the lock and allow you to register it under your own account. If you encounter any issues or need further assistance, I recommend contacting the Customer Service Team through the Aqara Home App (Profile > Help & Feedback > Customer Service) or by scanning the QR code:

Hello @info164
The administrator password is very important as it is a mandatory function for aqara locks, please contact the support service by email support@aqara.com I hope they can help you in this situation.
If you have the opportunity to contact the seller and find out his email from his Aqara home account, do it. This can help in restoring access to the lock.

Hi Ondra! I am facing the exact same issue with a secondhand U200 right now. Did the hardware reset steps provided by the bot actually work to remove the previous owner’s account for you? Or did you end up having to contact Aqara support to unlock it remotely using your receipts? Any update would be greatly appreciated. Thanks!

I got this from support last week. It worked, but only on the fourth or fifth time.
Hope it works for you if still relevant.

To factory reset the Aqara U200 door lock without the admin PIN, you can use the Matter pairing code as verification. Please note that this method requires firmware version V80 (3.0.0_0080) or newer.

Steps to reset without admin PIN:

  1. Confirm the U200 firmware is V80 / 3.0.0_0080 or newer.
  2. Press and hold the 0 + 9 keys on the keypad together for about 10 seconds.
  3. When prompted for administrator verification, enter the last 8 digits of the Matter pairing code, without the dashes.
  4. Press the Confirm/Validation key (✓) on the keypad.
  5. Wait for the factory reset to complete.
  6. Add the U200 to Aqara Home as a new device.

Where to find the Matter pairing code:

The Matter pairing code is printed on a label on the U200 door lock itself. There are two QR codes/labels on the device: one is the Matter code and the other is the Aqara installation code. You need the Matter pairing code (an 11-digit code). Use the last 8 digits of this code (excluding any dashes) for the reset verification.

Please be aware that resetting the device will clear all data on the lock, including schedules, battery level records, and connected sub-devices. After the reset, you will need to reconfigure and re-pair the device.

If this method doesn’t work or your lock isn’t up to date, unfortunately, the only remaining option is to use the administrator password. We apologize for any inconvenience this may cause and appreciate your understanding and patience.

This saved me! Probably good to add it to the FAQ and manual of the device on the website.
