2006 Infinity M35

[techterr]

Went to program a prox key to a 2006 Infinity M35 the other day and ran into problems... Pulled the BCM code, 8AD12 and then converted into pin code via software, 6128, pre 2008 and also 8725 post 2008.. Tried both pins but it said wrong pin each time. Does anybody know if the 06 M35 has a universal pin like the older Nissans? or is this a grey market car that my pincode software won't work correctly?
Thanks for any and all ideas,
Tim
