I'm working on a semi-puzzle adventure mod (that should go for about 5 minutes). The idea is you can travel between Morrowind and Oblivion time Ald-ruhn to get some goodies (Ebony Dagger, Daedric Pants, random provocative red gown).
The script I'm having trouble with is enforcing the mandatory rule where you need to have a key to open the door. I don't want those pesky and glorious 'Scrolls of Ekash's Lock Splitter' ruining the puzzle fun. I usually find scripts ingame or in other mods and modify them to suit my problem, but I can't find them in this case.

So, would someone be able to whip up a (what I assume is basic?) script where you must have a key in your inventory or the door will not open? I *could* make it so when you pick the key up you get a journal entry and then the door automatically opens, but I was hoping to avoid journals in this. Anyone that helps can have the mod dedicated to them, in loving memory. Like, a living memory. Woohoo!
Thanks in advance,
Sam
