I have keys and pickup rings & ecu,s mate recoding was £120 at nissan in sunderland takes them all of 5 mins to do, but you have to book it in and leave it, daylight robbery I know but as they are the only ones who can do it you dont have much choice to shop around.........but if your going for recode then you dont need to match keys and pickup rings just swap ecu tow it to nissan and get it recoded they will then recode everything............been there done that
