I need help with my wii remote!

So, I've had this remote for a long time. The remote wouldn't stay on. When I returned to it, the batteries decroded inside it and the decrosion got onto one of the readers. When I told my Dad about the issue, he fixed the decrosion, lickity split! The remote still will not stay on. I don't know where to go with this. Call Nintendo? Get repaired elsewhere? I don't know. I will probably update on the situation soon as soon as I make a move.
