How would you reprogram the keyless entry door locks on a 1985 Nissan maxima?

Answer 1

I borrowed this from Nissan forums... http://www.nissanforums.com/showthread.php?t=74930 get a flashlight and look under the dash on the right side of the car. you'll see a gold colored box... it'll be against the inside of the fender wall, beside the glovebox. It will have a bunch of numbers typed on a sticker.. I believe it's the middle number, starting with F or something. write that number down.. there should be 6 or 7 digits in the number part of it. (ignore the letters) now get back out of the car and hit the CLR button on the keypad... then punch in the numbers from the code into the keypad. when it's done, it'll make a long constant beeping sound. now enter the NEW code you want. it has to be at least 3 or 4 digits, can be up to 7 or 9 or something... can't be consecutive numbers or the same one or anything like that. when you're done punching in the number, stop pushing buttons and just let it sit for a few seconds.. it will continue beeping for a short while (10-30 seconds, I forget), then a bunch of short beeps.. after that, the new code is entered. lock and close the doors, then wait a few seconds for the system to think.. hit the CLR button and then enter your new code on the keypad. when you finish, it should unlock the doors, roll down the front windows with the WDW button, and pop the trunk with the TRK (or whatever) button. I've seen another note that says the sticker is behind the glove box (remove it to see it...) Another note says it's in the trunk on the pre 1989 models. adding this to my bio page
