The module will need to be reprogrammed to recognize your fob(s) and possibly other sub-systems. IIRC, this has to be done by a Nissan dealer for security reasons.

I haven't seen it mentioned anywhere, but you might be able to get the fob that belongs to the used module and not have to reprogram. Just a guess.
