The following year Keher won his first Leinster medal following a 2–10 to 0–9 defeat of Dublin. This victory allowed Kilkenny to advance directly into an All-Ireland showdown with Waterford on 1 September 1963. "The Cats" entered the game as underdogs, however, Keher proved to be the difference with a magnificent display in which he scored fourteen points. Despite a hat-trick of goals from Waterford's Séamus Power, Kilkenny secured a 4–17 to 6–8 victory. It was Keher's first All-Ireland medal. He later won his first Cú Chulainn award in the inaugural year of the awards scheme.
