I need a security code for my nissan primastar radio?

you need to remove the radio.
they are too small holes each side of the radio
use an old metal coat hanger 4 darts or very small screwdriver or long nails.
put into holes about 4-5cms and push outwards sideways
and carefully pull radio forward.
you must do the holes on each side at the same time

Then post the numbers/letters from below the main barcode
something like 7700xxxxxxtt123 or 8200xxxxtt123 or
the security code like Q123 or T0U123
can be found in a small box then i can help you
off of the radio
