keypads on the doors??

 

yeah, you can definately do this, there is a little spot under the dash passangers side i believe that has the original code on it or something, i dont remember its been a long time, if nobody responds on here or if the search function doesnt help you out, call your local nissan dealership they will tell you how to do it, they might even do it for you for free, to try to get your business.
