Just got a few terms wrong I think

your Goldie (if it was in the box at the time) would have received an EMK (680D nano), thus changing the the PMK and possibly the Provid.............
So you should be able to find the new PMK for your details from your Goldie.......LMedit or such will allow you to see it easily.
Now to get your Sub running again............it does depend a little on the version, but basically what you do is send the card an EMK command (the same as what has happen over the air) via a phoenix programmer.
So if you have the HMK, the new PMK, the Provid you can calc the EMK, (you could just get the EMK from a logger of course) and the sig...........FM card has all the stuff you'll need.

Hs = HexSerial
Mk = Emk
Pr = ProvID
(Si) = Signature if required
