lock door help

[Itskody]

Just to verify, is the problem, not being able to use the key on the door or the key isn't unlocking the door?

not being able to use the key on the door, the names atr all right, and i have done this like 10 times before unlocking other stuff, but for some reason the door doesnt wantto unlock... ill tell you what my map is..


My guy goes through the first map and at the end, there are 2 doors, one is the study and one is upstairs, (both level doors), the upstairs door is locked but the study door isnt,. so you have to go through the study door to the second map to get the key for the upstairs door. but when i get the key and come back to the first map, the key doesnt unlock the upstairs door to the third map... lol get it?

soo

Map 1 > Map 2 > Map 1 > Map 3.

iuno how to explain it any other way
