To clarify, the key covering is first removed and then the surface is 
milled to accept
the new covering. Since usually the new material is thicker than the 
original, the
height of the key stick needs to be adjusted to account for overall 
key + covering
height.  Sometimes even an factory installation can be improved upon in regards
to the natural to sharp elevations.
