The database key is tied to the card and has nothing to do with the unit.
The unit just displays the database key of the card inserted because you
need to know it for the Internet download where the key is inserted into the
download.

You can download an update, burn it onto the card and then use that card in
any unit. Wingman customer support at Honeywell/King doesn't know this or
chooses to lie about it as some form of copy protection (although I don't
know what it buys them).

I know all this because we manage multiple KLN-94 units and we burn the
updates using a single GPS unit. There may be ways to beat the copy
protection using the separate card burner. There is no obvious way to beat
it using the GPS units to do the burn (not that we've tried, seriously, we
haven't, we're just happy it works as is and is half price).
