Landlord Won't Give Us Keys To Replaced Lock.

So me (26f) and my roommate are living in a rental condo in Indiana. When we first moved in our house had a really bad lock that had a hard time opening from the inside. This was irritating, but we had keys to lock and unlock the doors.

The landlord came to replace the locks two weeks ago and lost the keys that day. We have never had keys to this door, which means we no longer have keys to any door in our house and we either have to maneuver in the mornings to not lock someone out, or we have to leave our door unlocked.

What in the world do we do here? This isn't our fault and no one (including the landlord) is arguing that it is, but he is still taking his sweet time and won't do anything.

I have all of this in provable writing and, again, no one is saying we need to do anything. On top of this, the landlord wants us to do a bunch of stuff like moving things that belong to the homeowners so the HOA can do yard work, etc.

Nothing about any of this has been in the lease and honestly this guy has been a nightmare.

Do I have any action I can take moving forward to fix this?

Thank you!
