column lock won't unlock

This morning I let 2002 C5 roll down the drive way before I put the key in the ignition. Then I put key in and I the "pull Key for 10 sec" message follow by the" service column lock" message. Now 8 hours later I still get the messages. The car will start but will only move a few feet before it stalls. I am really bummed. Any help????
