No idea what you're talking about "the swap was done"... Sometimes you're lucky... check every page of the owners manual... someone has usually written it down in there if you can't find the card. you'll have to pull the deck out and give the dealer a call with the serial # on the deck.

i had an engine swap, when you disconnect the battery and reconnect it again, it wants the code.
