I screwed up and couldnt edit .....here the process
This is for anyone wanting to know how to code an original nissan keypad to there car...this was done on an R34 GTR but seems to be generic for nissans:
1.get in the car and manually lock the door
2.insert the key in and out of the ignition switch 6 times,the doors will unlock by themselves
3.Insert the key without losing rythme and turn to acc,and relock dors manually,then push the button on the remote.
presto,you have a coded remote
