I tried your suggestions darth_trethon,
I was able to lock pick that door but when I talk to the immaculate guy he gives me the same dialog he did when I was at his chapel. I even went through the trial by by glitching with they pyramids but it didn't register as being completed.
my question is do I need to complete this quest to proceed in the game? (I was able to pickpocket his keys at least)
