The new master key register must be Empty in order to load a First key part. It must be Partially full in order to load an Intermediate or Last key part. You must load a First and a Last key part, and you can load any number of Intermediate key parts (zero or more).

After selecting the popup menu option, you are asked to select the source of the key part.
