How to change keydef name in a keydef list?

I am trying to make changes to the keydef list. Specifically, I am trying to change the name of an existing keydef. When I make the change in the navtitle I can check the file back into Windchill. When I try to make a change to the href or the topicmeta conref I get an error when I try to check in the file.

Note: I had to rename the folder and the object in Windchill. So I need the keydef to recognize that both have changed, not just the object name.

Thanks
