Hi

Have a FX45 -03
Suddenly the power locks stop working.
The key "talks" to the car. I can roll down the windows by pressing the button for 3 sec and that works.
The power locks works when i use the metalick key in the door and when i press the button in the door panel.

Any idees?

Sounds like the door lock actuator going bad. Pretty common among the nissan/infiniti cirlce. Many threads on replacing it on this forum, g35driver, and my350z.
I used lock actuators from partsexpress with good results for 4 years now, but some will say use oem. I had to replace 3 of my doors already and its all custom work. Not hard if your handy with some tools and common sense. It'll start off by being weak, then complete failure, then the other doors will follow eventually.

The driver door lock/actuator does not send signal to other door locks/actuators. The signal is from the BCM (Body Control Module). When the press the lock/unlock button on the driver door control unit, it sends signal through the BCM to the door you want to lock/unlock. If you use the remote to lock/unlock, the remote

Do you hear any noise/sound from the problem door when you use the renote to lock/unlock the door?
 
Not sure but it sounds like the OP is saying that the door actuators are working with the key just not the key fob if this is the case then maybe just need new battery in key fob.

Its all doors. Non is working from the button on the key.

Nois? Yes i hade some problems with the trunk door this winter. sunded bad when it looked it. Sonded like the engine needed to work a little to hard.

But it sound like i have problems with the BMC i guss then.
That shuld get some fail code in the ODB.

Cant be the key fob as it sends down the windows and i have 2 of them and non works for the door locks.
 
I mean any noise or sound at the door actuator when you use the remote fob to lock/unlock the car.
