I have a KLN 89/B and I put the wrong DBkey in the first time I used it.
I called Honeywell and they gave me a free extesnion to my subscription
and I just downloaded a new request using the correct DBkey. I didn't
wind up having a useless card. Now if I could only take the card and
program it and not have to take a laptop to the plane.

The database key (which changes occasionally) is linked to the card,
not the unit. If you have multiple cards for one unit, you need to be
careful which DB key you use - write the wrong one to the card and
it's useless. Ask me how I know.... But you can take a valid card
and shove it in any KLN94 and it'll work just fine. Anyone who could
successfully duplicate the entire card, including the DB key storage
system, would have a fully functioning card for any unit.
