I just had my save game repaired by support because of the Alrick/Raze/Moor NPCs being in the wrong spot ... and now I am in this situation too. Stuck in the bandit cave with no key. Can't get past the gated door, can't get past the force field ... and therefore can't finish those quests. I noticed as well that I have a similar issue in the imp cave ... killed everything moving, no key to get past the gate.
Same problem? Seems like it, and it's highly discouraging.
