On a '12 it should use the method with the door lock button plus in-out 10 times in the key cylinder. I recall a bunch of threads in here describing it, but basically you begin the procedure by locking the doors using the button, then insert and remove the key quickly over and over until you get a double-flash from the hazards. Then insert the key fully and turn the ignition on (don't start). Press the "lock" button on the fob and the car responds with another double flash. To register a second fob, press unlock and then lock on the door, then press "lock" on the second fob. Repeat for more fobs, I think the limit on a Versa is 5. If you get the car into registration mode but there's no response from the fobs, then the problem isn't the BCM's memory. To avoid a lot of screwing around, visit the dealer and see if the fobs are transmitting (locksmiths can generally check that too). Then you'll at least know where to start with the diagnosis.
