Apple Wallet Key is missing

Any idea how to get it back? Should I remove it from the hub and rebind it? or reset the a100 ? if reset I was told I need to have the master code… what is the master code? need help here…

Thanks in advanced.

Hi,
Normally unbind and bind it back should solve the problem.
But what’s the master code , I don’t know because I don’t have a A100 - was you able to set a Master code at the beginning of installation?
