Grimrock

Hello, so i am new in here, just registered to create this topic, so i apoligize if i dont follow forum rules somehow, or if this has been debated a ton of times.

So i have currently more or less finished the sewers, and areas around it but i am stuck because i am really annoyed that because i chose to flee from the ratt boss and kill him outside i don't have the key to unlock the next area in the sewers, where the next power gem is staring at me, (the brass key i think).
I have allready searched for this a few times with no luck.

I am looking for any solution, i dont care if i have to cheat, would just spawn the key if i could get the console to work, though people advice against this, i have no prior save before him.

thanks in advance

what i did was i ran in, grabbed the key, used it to get back out, instead of staying and fighting

never mind went back and triple checked the room, there was another key on the floor in there apparently, feeling stoopid ^^

Dont feel bad. I murdered everyone in that room in about 2 minutes, and then spent 30 minutes looking for the damn key
