100% Vault Key Drop - Mirage's Party Boat
Not seen this as widespread info, but if you shoot the 'Disco Ball' that looks like a loot box in the main room on the boat, it contains some loot and a vault key!

That is because it is a loot crate. It doesnt always have a vault key from what I have seen.
It is surprising when I go there halfway through a game and everything is looted but that is still there.
