When I read the terminology between FMEA key date and FMEA Date (Origin) on 3rd edition of FMEA manual reference, my first perception is key date will not change but FMEA Date (origin).
Any comments is appreciate. Thx.

Key Date--Enter the initial FMEA due date, which should not exceed the scheduled start of production date.
FMEA Date--Enter the date the original FMEA was compiled, and the latest revision date.
The "Scheduled start of production date" may change, and often does, so the PFMEA should be updated accordingly. ...I think they want the date that the original document was created, rather than the date when the PFMEA process began, but I prefer to use the latter because it's a more accurate indicator of the chronology.
So to answer your question, the due date might change, but in general the orgin date won't.
We use the date that the first draft of the document was created as the original date (which does not change), and apply revision dates for subsequent updates of the document. This agrees with Jim's reply.
Key date is murkier: this past year, because of one of our customers' demands, the key date field has been expanded: where we previous used start of production as our key date, now we must reference DC's PDDC date (product design & development complete) as the key date. This date is fixed for any particular program.
For our non-DC programs, the key date field also includes either next PPAP date or last customer approval date (ie. most recently completed PPAP). Since our PFMEAs apply to families of parts, these dates do change as programs evolve.
