OBS columns are not bad to work on, but as Far as I know, the tumbler has to turn to remove it. There is a small ball bearing in a hole underneath the tumbler. It is easier to see if you take the column cover off. You have to press that bearing up towards the tumbler as you turn the key to the ON position, them the tumbler will pull right out. Now, if the tumbler will not turn, I don't know what you can do to get it out. Maybe go grand theft and try to break the tumbler out? No, even as I said it , it sounds like a really bad idea. I looked for the other thread with details, but couldn't seem to find it. What exactly is broken off in it, and will it turn at all?
