programing a Nissan remote , is hidden secret by Nissan Dealers. I have a friend that works for a Nissan dealership.
Just get in your vechicle , close all doors. Using your power lock switch , lock all doors. After doors are locked take your Ignition Key and insert it and remove it from ignition switch in a slow fashion , but consitant pace. (97 and earlyer are fast) When you see the hazzard lights flash, put key in ignition switch and turn to the On postion .. Do NOT CRANK or you will have to Start over .. After in the On postion .. Hit the Lock button on remote... Hazzard lights should flash..( note..you have to reprogram all remotes when adding a new one , if you don't your old remotes will not work ) If your doing just the one , turn igntion switch off and unlock door and get out and try it. If you are doing more than one. While still in Vech with Key on . After you hit the Lock button on Remote and hazzard light flashed .. with key still on .. use master lock switch unlock doors and relock and then hit Second Remote, Lights should flash again , repeat if adding a 3rd remote.. after done just turn key off and unlock door and get out and try. Good Luck
