Cheers for your help. Nissan have been near useless. Though Nissan logo alarm keyfob and supposed to have been fitted as an option when new they can't trace model or how to get replacement even when desc given of keyfos and the codes printed on a sticker inside. They stated most were Max2 alarms. Not trace on google. Tech-tronic Manchester have told me must be rebadged Cobra alarm for Nissan. Codes given and they said they can do a new fob for £36 on the spot! Also found another uselful site http://www.alarmremotes.co.uk/ who will do for around the same price. They also do one which will scan your original. . Just re-soldered mine and taped up case and works ok for now. Will order the spare though. All in all, been quite a useful experience.
