Wrong key in ignition

Accidentally put my Sierra key in Civic ignition only realizing this mistake when the engine turned over but failed to start which made me look close. Dang! Wrong key then (GASP!) Key won't release.

I tried all the usual "fixes" and have removed the steering wheel housing. Can I remove the ignition and then reinstall?

Of course I'd check to see if the ignition still works with the original Honda key.
