Without actually looking at the bike what I think you're gonna have to do is pull the ignition switch off the bike and then see if you can rotate the pin out of the way. Then you might as well take the steering lock off and use something else so it doesn't happen again. Some bikes where the ignition switch also works the fork lock if you take the switch off you can use something like a screwdriver to rotate the lock out of the way.
If you can get it apart you might be able to repair it.
