Central locking not synced

[Nissan Note]

Hello, can anyone help please. My central locking is out of sync. When I press the fob to unlock the doors, the 3 doors and boot unlocks and the passenger door locks. 

Then when I press lock, 3 doors and boot locks but passenger door opens. 

I can lock and unlock the passenger door with the key.  

I have changed the fob battery and disconnected the car battery, but no joy.

Any ideas??? Please :)

sounds like the connection has been reversed on the passenger door lock mechanism - has any work been carried out on the car recently?

Yes, my fan inside the car, that blows on the windows was broken and the mechanic fixed it. Then this problem happened.  

Do you know if there is a way to reverse it?
