The 27-year-old, who turned professional with the Blues in 2003, was due to be a free agent this summer.
However, the Republic of Ireland shotstopper has now committed his future at St Andrew's until 2015.
Doyle is expected to feature heavily for Birmingham next season following Jack Butland's departure to Stoke City.
