Stuck at Vending machine.

[ArthasGaming]

Hello everyone, I am at the part where you find the gravesite that leads down to the waiting room like area, where the big metal door is, I have exhausted everything I can do there, I looked at the vending machine did all I could there, found the mop but all it says when I click it is, its a dirty old mop, I dont know what I am missing if anyone could give me a hint I would appreciate it, I am loving this game just for some reason this part has me stumped.

You have to get the 'key' chocelate bar from the vending machine. You do not need to insert a coin. You can press the number and character buttons at the top right side of the machine but their inscriptions are not correct. You have to watch which of the keys produces which character/number and then press the correct three keys for the chocolate

There is a "no payment needed"-mode for the vending machine, that you have to activate first. There was a clue on a piece of paper (found in this room) which buttons you have to press first to enter this mode. After this, you have to type the right buttons to get the key card chocolate. But beware; the keys are scrambled and you have to find out which keys belong to which number.
Good luck!
