Well here is a quick and nasty little one I made for my own use.
Requires you to be in the vault, with the force field already off. Turn ObjectGatherer off because it messes things up a bit.
No bagspace checking or anything fancy, and it will do one round of checks even if you run out of keys.
This a really poor profile, but it mostly works and saves me a bit of time. Let me know if it works for you too.
Edit:
I forgot to mention the place you have to be is the room you get to by turning left once you get inside the main entry. It will only work in that one room at the end of the trap tiles (not the one where the Dragon is). I hope that makes sense!
