I took off the steering wheel and managed to get the lock assembly removed. I cant seem to get the wire plug on the back disconncted though. It is locked on or something? I still can't get the key o turn no matter what I do.

EDIT:
I got it out after turning it and hitting it with a hammer a few times, and removed the wire and the little thing the key goes into. Both seem to be going bad Where would I get a new assembly that will match my key?
