Hi everyone,
If you’ve updated your U200 to the v80 firmware and noticed that your Home Key has disappeared or stopped working, here are a few steps that may help you recover it:
IF: You have previously enabled the pull spring function
Please restart Pull Spring function after updating to ensure the door lock operates normally.
IF: Upgrading from v78 to v80
You’ll need to reset Matter and rejoin the Matter ecosystem manually after the update.
IF: Upgrading from v65–v77 to v80
If you’re running into issues, try this workaround:
(a) Remove the keyboard’s battery
(b) Disconnect the Apple hub’s power (HomePod Mini / Apple TV etc.)
(c) Wait for about 1 minute, then power everything back and try again.
IF: Missing Home Key card after the update
If your Home Key card disappears, update your iPhone and HomePod to iOS/tvOS 18.4.1 or later. Then, use the new feature called “Restore Home Key Access” to bring it back.
(Home app> U200’s setting> Manage Access> Restore Home Key Access)
To reset Matter without affecting your Aqara data (fingerprints, passwords, etc.):
Hold the lock key for 5 seconds until you hear a voice prompt.
@KinseyCreateGoods Thank you for sharing these helpful tips on handling issues with the U200 after updating to the v80 firmware! It’s great to see such detailed steps for different scenarios. The process of resetting Matter and rejoining the ecosystem manually after upgrading from v78 to v80 is particularly useful. Also, the workaround for those upgrading from v65–v77 is a handy trick to remember.
For those who find their Home Key card missing after the update, your suggestion of updating devices to iOS/tvOS 18.4.1 or later and using the “Restore Home Key Access” feature is a fantastic addition. This kind of proactive sharing enriches the community and can save users a lot of frustration.
Thanks again for contributing, and please continue to share your insights and experiences with us!
I’d like to ask you to briefly review the issue at
IF: Upgrading from v78 to v80
You’ll need to reset Matter and rejoin the Matter ecosystem manually after the update.
Many would like to take this step but do not know to what extent a reset takes place here. According to the instructions, a reset is only possible completely, including all fingerprints and passwords, which is very problematic for larger families to set up everything again.
Hence the question of how to do this correctly without problems, for example with the Aqara M3 or how is it done correctly with the Apple Boarder Thread device?
Because unfortunately it is currently difficult to test the step
Thanks for remain! I will update these on reddit
If you have already set up Aqara Home, you can use the local menu to reset Matter separately. This method will not reset your Aqara user data (such as fingerprints, passwords, and settings):
Press and hold the lock key on the keypad for 5 seconds until you hear a voice prompt
Then enter your Aqara administrator password.
Press key (4) to perform a Matter reset, resetting the already bound Matter ecosystem.
IF: You have previously enabled the pull spring function
