No, this doesn't have anything to do with Kingdom Hearts. Nothing at all. It's not even a reference to it or anything.In-game description
The Keyblade is modeled after the weapon from Kingdom Hearts- or perhaps just a normal key. It looks sort of like a bland, nondescript tan key with a very long shaft, no shoulder, and all notches/teeth being clustered at the far end of it.
