Link a Key to a Door

[Twitchez]

That's better!

Ok so does it give you error or does it just not work?

I didn't write the codes I used for example "wakeUp();", because that works like a charm. The problem is that when I enter my map, I go and pick up my key (which is named the way I want it). I go to my door, which is locked. I try to use my key, but it just says "Cannot use this item..."
