NFC/Home Key stopped working on U200

Hello, My NFC tag and Apple Home Key have both stopped working on my U200 installed 6 months ago. I’ve replaced the keypad batteries which required me to reinstall the Apple Home support but that had no effect. I’m running firmware version 84.

I can still lock and unlock the U200 with the Apple Home app, the Aqara app, the keypad, fingerprint and physical key.

Can anyone help? Thank you.

Have you tried removing the nfc tag and adding it back again? Sometimes this has happened to me and removed the nfc-added back and it corrected.

Another thing I’ve done is to remove the lock and add it back to Apple home resetting it in the process.

Hello, thanks for reaching out and sorry for the inconvenience.

Since the lock can still be controlled via the Aqara app, Apple Home app, keypad, fingerprint, and physical key, the lock itself appears to be working normally. When both NFC and Apple Home Key stop working, this is usually not related to the main lock functions.

Please try the following steps:

  1. Power reset the lock
    Remove the batteries completely, wait about 1–2 minutes, then reinstall them and test again.
  2. Remove and re-add Apple Home Key
    In Apple Home, remove the lock completely, then add it again to regenerate the Home Key.

Additionally, to help us further troubleshoot, could you please let us know:

  • The iOS version on your iPhone
  • The iOS / tvOS / HomePod software version of your Home Hub (HomePod or Apple TV)

If the issue still persists after these steps, please contact our support team at support@aqara.com with your purchase information, and we’ll be happy to assist you further.

Thank you, and we look forward to your update.
