Glove box lock problem on a 72.

[brown7373]

I replaced the non locking glove box button with a lock button 10 years ago. It has always worked fine until last week. Now, pushing the button doesn't open the door. If you insert the key, it will turn continuously either direction. Pushing the button with the key in it also doesn't do anything. As a result, I can't get the door open. Anyone have an idea how to open the door to replace the key lock? I was going to drill it out, unless someone has a better idea. I played with it for over an hour, and nothing will release it and let me open the door.
