Installing UAK key remotely with no HMC???

I do some work for a client with zero IT-staff on site but with their own
IBMi.



My task is to maintain and add changes to the application and occasionally
to add users or printers.



Recently a firmware PTF had to be installed and I felt sort of proud when I
managed to download the PTF and apply it last weekend.



BUT since then I have received communication from IBM that something called
a "UAK" (Update Access Key) has expired and a new one needs to be created
and installed.



I have also (again rather proud of that) managed to create said key and it
now resides in the downloads folder of my laptop.



This is where the success ends. I have found totally zero information on how
to get this spanking new key properly moved to and installed on the system.



Two things should be mentioned: First I work 100% remotely and reside quite
far away from where the machine is located. Second the machine does not use
a "HMC".





Ideas??
