ok thanks for the replies guys.
searched the bay, and found this
http://www.ebay.co.uk/itm/GENUINE-NISSAN-350-Z-REMOTE-KEY-NEW-KEY-BLADE-MODEL-/111027580399?pt=UK_Car_Accessories_Safety_Security&hash=item19d9c26def
So like above, i could get this, then take it to a locksmith, then try the rain dance to program it myself, if that fails, worst comes to the worst ill let nissan programm it, but still has to be cheaper as they are only programming surly?
