Hi,  there is a site called electrotanya or something like that.  THey have free SM manuals. It will help you with a teardown so you can get to the root of the problem.   A corroded button can also mean other corroded parts...  In my experience the gold fingers or gold contacts can easily be fixed with a good quailty conductive epoxy  silver.  That usually does the trick very well.
