Ignition switch doesn't lock up if you lose remote. Your problem is a bad ignition lock set and not the ignition switch it self. There are 2 pieces to the set up, 1 is the lock and 2 is the switch. If your key can go in and turn to the "acessories" or "on" position, then it can de replaced rather easily. If your key can't turn at all or won't go in,(lock set) it can still be changed but it's a little harder to do. You can do this with out replacing the ignition switch.
