List of door keys somewhere? I'm missing a key?

[RMCora]

Is there a list of keys that we possess that we can bring up somewhere?

Also, during the tutorial, after I was told about a free apartment after I lost my first one, I was supposed given a key, only to find the door locked and unable to be unlocked. Any ideas on this one?

you must have the "The Dead of Night" case active while talking to Efa Durand of 1002 Kapoor Heights, (I'm in Havana so the locations may differ but check E Durand in the city directory)

What incog said, but for your city and whoever it told you to go talk to. If you talk to them while any other case is selected, the person will talk to you, and say heres the key, but the story wont actually be progressed. You MUST have The Dead of Night selected, and then talk to them.

And no, There's no list of keys afaik.
