that year altima does not have a radio code.
pehaps you blew the fuse. try looking there first.
there is no security in the radio. there is no code to enter.
if your radio is lit up but there is no sound, you have a problem with the radio.
perhaps there is a fuse blown.. have you checked your fuses?
