He was elected as a Teachta Dála (Territorial Decoration) for the Dublin Mid–West constituency at the 2011 general election. He was a director of elections for Progressive Democrats candidate Tom Morrissey in the Castleknock local electoral area at the 1991 local elections.

Keating was comfortably re-elected in 2004, attracting one of the highest votes in the country.
He stood as an independent candidate for Dublin Mid–West at the 2007 general election but was not elected. He was involved in controversy after taunting the Garda Representative Association"s general secretary by issuing the statement: "Mr PJ Stone should put on a uniform and go and do real work and stop rabble-rousing."
During Budget debates in December 2012 Keating hit out at what he saw as a "Culture of Dependence" in Ireland, saying: “increased dependency on the State encourages a new lifestyle of welfare economy.. a woman will have a lone parent allowance, children's allowance, rent subsidy, school grants, a medical card, fuel allowance and special payments from the community welfare officer which come under section 13 of the Social Welfare Acting for exceptional payments”.
Later in December 2012 Keating returned €7,571 to the Government of expenses following a sample audit of expenses. In May 2013, Keating was accused by a school principal in Lucan of falsely claiming cr for getting an extension to the school.
His parliamentary aide, Tommy Morris, was then investigated by the Garda Síochána for taking c.3,000 copies of the Lucan Gazette (which carried the article) from local shops and dumping them.
Keating said Morris acted without his knowledge or consent. In July 2013 a protest held outside his home by a pro-life group led to him leaving as he felt threatened by their behaviour. The protestors had shouted at him to open the door and banged on his front door and windows.
He called Gardaí and provided names of people he had recognised.
Gardaí said that they had been called but that no arrests were made. He lost his seat at the 2016 general election.
