My passsanger door and one in the back on my Infiniti FX35 will not lock or unlock using the key FOB. I replaced the battery but it still dosen't work?

It is entirely possible that the unlock button on the remote is worn such that it is not making contact. I've seen this happen many times, as the unlock button is pressed so much more than lock. You might try to reprogram the remote first before you look into getting a new remote. The procedure goes like this. Close and lock all doors Key in and out of the ignition 6 times, hazard lights should flash twice Turn key into accessory or on position Unlock and lock doors with drivers switch Press lock or unlock on remote Hazards should flash again to verify recognition turn key off  manually unlock door and then open and shut it.  you should then be able to test remote. 
The key to the procedure is doing step two quickly Hope this helps, if not you may need another remote or see dealer.

I am relatively certain this has to be done at the dealer with the handheld diagnostic computer. They will have to access the Body Control Module and reset it. There are many options in the BCM menu that can be set. They should be able to do that rather quickly right on the service drive, and they shouldn't charge you since the vehicle is under warranty. If they don't then that is pretty ****. I worked for an Infiniti dealer for many years in the midwest and we gladly did things like that all the time for free just to take care of our customers.

the solenoid on that door is either shot or something wrong with the wiring..possible it has a fuse for each door but doubtful
