Sorry for the negative feedback, I was just mad that I couldn't figure it out. But here's what I do; I'll get the key and do the zodiac signs, get the stones then won't be able to get the black twist panel for the locks.
I just played through it to ensure everything was working correctly. The key you get from the face opens the small panel on the front of the box under the big door with the sigil on it. The black lever to unlock the eyeball is in that panel. I'm sorry you had a hard time. Have a great day!
