The key fob is faulty.
Passenger door wont lock or unlock.
When the physical key can lock or unlock the door be sure that the mechanism of the locks is fine.
These are mostly the reasons and troubleshooting options when a remote key won t unlock car door.

Door panel is easy to take off.
Sometimes the remote still does not work after checking for all possible reasons.
Also the rear doors will not lock or unlock in any fashion other than manually.
My guess is that it s either the solenoid or the wiring in the door or the wiring in the door jamb.
The key fob battery is dead.
Assuming it s the front passenger s side door we know that the smart entrance control unit and fuses are good because the rear locks work.
Anything else you want the.
Have you checked the fuses.
It won t work with the fob or by pressing the button on the door.
But the door lock on the passenger side will not lock itself completely which sort of undermines the point of having a remote to lock the car.
A fuse is blown.
Can you confirm the model of your nissan.
If one door doesnâ t work but.
Or does every lock have it s own fuse.
When you hit the power lock the lock switch moves partially into the lock.
The only way to unlock the door is to manually pull the handle on the inside.
