Hey Jojo, are you sure you’re looking in the right cupboard. It should be the one on the second floor building by fight arena. I’ll be on later if you haven’t managed to find it.

You're correct. The guide I was using didn't mention it was upstairs. I've sinced switched. However, when I take the next step and try to enter take Jeremy out of his cell with the Khazard keys, nothing happens at all. I don't even receive a "nothing interesting happens" message.
