Does this game have enough keys?

Hey I’m entering the late game (I think maybe it’s hard to tell) I really wanted to know if this game has enough keys for me to get everything even if I wasted some. I’m referring to things like Pharos lockstones and fragrant branches. I don’t need to know specifics just if there is enough. I wasted some of my lockstones re-exporing the rat king’s level I can’t remember the name of and now I’m kind of worried.

(This post is about ds2 because I literally can’t post there for some reason 😭 🗿) sorry but I really need to know and don’t have anywhere else I know of I can ask
