I been reading other threads on this but havent gotten anywhere. I have a 2006 Xterra. My wife went to unlock the door with the fob and nothing. so she used the key and wouldnt start. everthing else works. Battery ok. Lights are bright and all electronics work. I changed the battery in the fob and still nothing. When we turned the key I can hear the fuel pump prime and the relays click but does not try to turn over. Please help.
