I have a 1996 Nissan Altima GXE which I bought in 1997. The original key was broken. Had one made, then multiple duplicates. Now through degradation, the keys suck. I need an original but I don't have a code to get one. Nissan only goes back 5 years on their codes. Anyone have an idea of where I can get the proper code to get my keys made "WITHOUT" having to pull a lock to get a key made that way? Thanks!
