Firstly...It's Rank not level.

But moving on to your question.

Keys will not show up in your list, they're a "secret" item within the room that you have to find as you're searching for other hidden items.

You will however notice a counter at the top of your screen that will say 0/5 and that is how many keys you've found in the scene so far.

I hope that helps.
