Will this work on a 1998 mercury marquis?

I would say "NO" not listed for this year!! You can ask a dealer what the OEM Part number is and search that way also

So this should work for my 2004 grand marquis? I didn't see it listing.

Hi,This 4 button key fob fits for 2004 grand marquis Base Sedan 4-Door/Equipado Sedan 4-Door.Thank you.

Does it open so I could just transfer my existing board into the case?

Yes, in fact that's exactly what I wound up doing because I couldn't get it to program. Yep, just pry it apart and transfer your board and push pad!
