Smart Lock U200 – impossible to bind (Hub M3 / HomeKit) after full reset and fresh setup

[carlos_pereira]

Hi everyone,

I’m stuck with a blocking issue on the Aqara Smart Lock U200 and looking to confirm whether this is a known problem.

I cannot bind the U200 to Aqara Hub M3 nor to Apple HomeKit. I’ve already:
• Replaced both the U200 and the M3
• Started from a completely fresh setup (new Aqara Home, no legacy Matter/Thread devices)
• Removed all Matter history from iOS
• Tested on iOS and Android
• Performed multiple factory resets
• Confirmed latest firmware on both the lock and the hub
• Tried all community and online workarounds I could find

Same result every time: binding fails and the lock is unusable.

I’d like to know:
• Is this a known issue with U200 / M3 / Matter?
• Is there any advanced reset, firmware fix, or escalation path that actually works?

Thanks in advance.

Hello, welcome to the forum. Maybe this topic from the “documentation” section will help you Common mistake when adding Aqara locks (QR code not supported) - solution inside!

Another question, did you delete the Tried network in the M3 gateway and create a new one? It helped me.
