I have a tenant who says she rarely uses her garbage disposal. However, it is
seized up when she does try to use it. Is it just rusting to the point it
won't turn? If so, is there a way to lubricate it to keep it from rusting?

Tell her to run it more often. It is getting jammed up by stuff she
does not think requires the disposal to get rid of. A dishwasher is
famous for that.
