Mapsource 6.16 store its unlock codes in a text file, you can simply copy it to your second PC. Files is %APPDATA%\GARMIN\Maps\UnlocCodes.ucx, on Windows XP it should be something like:

Unlock codes from previous versions of Mapsource are in registry. You can save registry branch and restore it on other PC. It is in HCU\Software\Garmin\MapSource\Codes
You can import the codes to another PC by launching the exported REG-File
New Mapsource reads from file and from registry too.
