Adding user codes across several different Aqara smart locks models

I am an absolute newbie to smart home setup but am tech savvy. I want to use a U400 smart lock on my front door, a U300 on entry from garage, and a U100 for basement entry. Can I setup codes for family and friends, etc. for one device and easily add them to the other ones or do I have to re-enter for each device. I will be new to Apple Home and Aqara apps so I don’t know which I would use for this, that is if one is easier.

@geniede You seem to be experiencing an issue with setting up user codes across different Aqara smart lock models (U400, U300, U100) and wanting to know if codes can be synced between devices instead of re-entering for each. You can contact customer support for assistance.

Contact the Aqara Home App Customer Service Team (Profile> Help & Feedback > Customer Service) or scan the QR code:


This will be more efficient. If you do not have an Aqara Home account, “Please click here” to create a ticket.

Hi, the easiest way for me it’s over Apple Home. There you can set a password for family or friends ( with different times) for all added locks With one invite

I agree with @DEChrisE The easiest way to achieve this is through Apple Home. Once the password is set here it will translate to all entry points.

Thank you. Now I feel good about buying three entry point locks.
