Question

How do I program/register a key on my 2002 Nissan Altima 2.5L? My new key won't work, and I got the engine codes P1612, P1614, and P1610.

Hi there,

This can only be programmed by the dealer or a mobile locksmith. Nissan can only be done using a scan tool so this isn't something you can do at home.
