Before trying to code the fob with PScan I would advise you to check that spare fob does not have dry soldering or some elements missing. In case of dry soldering resync will not work, you would need to resolder the fob and try to resync again. If elements missing then you will need another fob in order to resync it or programm it.
One question popped my mind as I cannot see from which year is your car - what type of fob you have? If Pektron fob (oval with logo in the middle) then resync is not necessery.
