2004 Saturn Ion -Trouble with turning the key to start

Does anybody know the remedy for an ignition problem where the key won't go to the start postiion? Its been plagueing me for a while but is getting worse. I have to turn the key and wiggle the stearing wheel to get it to go. Thanks in advance for any advise.

The tumblers in the lock cylinder are worn, or the key is worn, or both. You can get a new key cut, and spray some Graphite lube into the lock cylinder. Make sure to use a "dry" lube. If it still binds with the new key, the lock cylinder will need replaced and coded.
