I recall earlier Nissan Maximas having a row of buttons on the door so I just googled "1991 Nissan Maxima Keypad" and briefly looked at some links that came up on how to locate themaster reset code. I think your picture would help, and maybe a locksmith would be able to tell you who makes the pad if it is aftermarket. Usually the installer's contact information would be somewhere in the car.
I am just as curious about this keypad. I am willing to post your picture for you, if it would save you some trouble.
