My right-side door lock cover had been missing its spring and now it seems that its pivot shaft has broken.

Is it necessary to change the lock tumblers in order to replace the lock cover? These are from Mac's auto parts. They do not have the arms sticking off the back like used ones I saw on e-bay. Is the part with the swing arm a socket that the lock tumbler plugs into?

Door lock tumblers on e-bay with arms on back. Are the arms removable or are they part of the lock?
