Hi, I need access to a closet, behind some bathroom tiles - but there's a lock (see attached photo).
I just moved in, and don't have the key.
It fits a normal square utility key; that turns it some way, but the door won't open. It also has a groove in the middle.
I've asked at a utility store, but they said they didn't have what I needed.
What key do I need, and where can I get it?
Thanks.
