Lubricate the pin....not the door....

Looking back through this topic, I'm more and more inclined to believe the problem is that you are not getting enough current to the unlock solenoids to make them operate - probably zero current. I find it difficult to believe that so many solenoids would go out at the same time (but it's not impossible). So the first place I would check would be the fuses and relays supplying actuating current to the solenoids - probably in the IPDM; FSM will tell you for sure. While you have the IPDM open, use a voltmeter to verify you have the unlock signal coming from the BCM (or wherever it comes from) to the IPDM circuit board. How to find all those test points, fuses, relays, etc will be in the FSM; along with Nissan's troubleshooting procedures.

I did have one gone bad before, it was a 2011 FX50. Luckily, there’s a small access hole from the cabin where the solenoid was reachable...I ended up unplugging the power to it, became always unlocked until I had to to send the car to mechanic. Very frustrating when trying to fill gas and couldn’t get the darn door to open.

Hi everybody,

I can open the gas door, the keyfob works great know (I do not know how)
After a few weeks it works great !!!

Hmmm. Mystery. Glad it is working now.

You can buy new solenoids (latch) on ebay and replace in minutes from inside the rear bumper cover.

Hi everybody,
it only worked 2 days and today it works again .... I see that it works after a long trip, there may be a report ?

On the other hand, the button for unlock all door (driver side) did not stop working. He worked very well.
BTW,* I have an appointment with car workshop (not Nissan) next Thursday, they only repaired japaness car. Maybe they help me but the key work now ... very strange problem.
I can check wiring problem with them ...

the problem is the unlocking of the doors and the gas door.
Keyfob and the button on door (driver side) was not working.
