Korg Kross 2 88 Key Popped Out

Hello, someone mishandled my gear and had the E4 pop out of place, I’m hoping the keyboard parts are the same as the original kross 88 that are on the syntaur marketplace, but I’m just not sure. How would I go about fixing this? Would I also have to replace the hammer weight? or do I just have to re-set the key and not buy a new part at all?
