During the People Power Revolution of 1986, Keithley helped comandeer the offices of DZRJ-AM radio station in Manila, where she along with Father James Reuter, set up Radyo Bandido, which served as an alternative source for news of the uprising after the destruction of Radio Veritas' transmitter by government soldiers on 23 February. As government forces failed to discover their whereabouts despite their proximity to Malacanang Palace, Radyo Bandido helped sustain the momentum of the revolt that ultimately toppled the dictatorship of President Ferdinand Marcos on 25 February.

In 2009, Castro was diagnosed with breast cancer and told she had three years to live.[5] She died, aged 66, on November 24, 2013, at St. Luke's Medical Center, Quezon City, Metro Manila.[6][7]

Presidential spokesperson Edwin Lacierda issued a statement announcing her death on Philippine television.[8]

Castro hosted a religious program called "The Woman Clothed with the Sun".[9]

During the administration of Corazon Aquino, Castro was conferred the Philippine Legion of Honor, becoming a reservist in the Armed Forces of the Philippines with the rank of general.[10]

In 2013, she and Reuter were given a plaque of recognition and the Spirit of EDSA award during the 27th year commemoration of the EDSA People Power Revolution.[11]

Keithley was portrayed by Odette Khan in the 1988 Australian television film A Dangerous Life, in a scene depicting her role in Radyo Bandido during the People Power Revolution.
