Need some help with the workshop area

[Sacre]

Im stuck also, I try and input the code "which i know!" and i cant.. because nothing happens when i click the keypad, no extra window appears, i just click...nuttin...no sound.. nuttin..

So, I can't input the code. So, I figure ill try and blow a hole with the TNT but I dont have a fuse, and I've searched all shelves and rooms and I cant find jack, been stuck here since last night

Spoiler below!

there is a sheet of paper by that blocked exit, the code is on that paper.. i cant input it though because when i click on the keypad nothing happens.. and when i click the door it just says "its locked"
