you may have a weak car battery. when my car batter was dying in my 95 maxima my remote stopped working, when i finally got around to getting a new battery it started to work again. i don't wanna say that's definitely the problem but that's what happened to me.


you could also try to reprogram it:

Programming Instructions from the Nissan/Infiniti Factory Shop Manual

First, for entering "Setting mode": (1) Close and lock all doors. (2) Insert
and remove the key from the ignition more than six times within 10 seconds.
(The hazard warning lamp will then flash twice.) At this time, the original
ID codes are eliminated.

ID code entry: (3) Turn ignition key to "ACC" position. (4) Push lock
button on the new remote controller once (for example, if door is locked
using the remote controller during this ID code entry enable state, a new ID
code can be entered). At this time, the new ID code is entered. (The hazard
warning lamp will then flash twice.)

Additional ID code entry (5) If you need to activate additional remote
controllers, unlock the driver's door, then lock again with door lock knob.
(6) Push lock button on the additional new remote controller once. (7) This
ID code “entry enable state” and setting mode remain until the driver's door
is opened.
