I have a honda civic 1991 and someone broke in to it and put a screw driver into the ignition and now the key won't turn in the ignition and I was wondering about changing it myself. Is it a hard thing to do and how much would it caust for a used ignition. Apreciate the help.:D

I would say it's medium difficulty for most people. Not sure what it would cost.
