Had to rip to iso with ddrescue, have disc and ISO but "volume key is unknown"

Hi all,
I have a faulty disc with about 5mb of bad sectors. MakeMKV can't rip it normally as it fails to read the title.
I *was* able to create an iso using ddrescue and lost about 5mb of the 40gb blu-ray. Funnily enough, given the position in the title with the error I'm 90% sure it's the intro sequence that appears the same on all episodes, so I'll be able to recut it with the intro when I do my encode anyway, or a small visual blip durin the intro I can live with.
Trying to load the iso using makemkv gives "The volume key is unknown for this disc - video can't be decrypted" along with an AACS dump file.
Given I have the disc and makemkv can rip it, how can I apply the deception key from the disc to the iso file when loading it through makemkv? I assume this is possible?
I'm assuming that `ddrescue` isn't going to be smart enough to decrypt since it doesn't care about the type of data or contents, but hopefully makemkv is and I can just apply the same key that is used on the disc?
Thanks for your great program!
