HELP Anti theft device tripped !!!

My daughter's iginition switch went out on a 2003 focus and when we took out the key cylinder the car started right up as directed in a post I found on here. My husband said "Shut it off to make sure it will start again" Why do I listen to him? After I shut it off it showed it had tripped the antitheft device. The manual says take it in for repair. OK Great. The car won't start to let us do that and we live 23 miles from town. Can someone please help me?
