2003 buick century won't start. Ignition switch goes clickety-clickety. Can still lock doors and the lights come on.

Problem occurred out of the blue just as I reached home from dealer servicing--TX inspection, oil change & lube, emissions servicing, and brake fluid flushed. Original owner and have 77,000 miles on car--regular dealer servicing.
