Peugeot partner lock problem

2004 Peugeot partner 1.9 when the vehicle automatically opens with the key, between the other doors are opened The driver's door does not open I open it with the key What is the problem? Thanks in advance

Locking motor like malfunctioning. Does it lock when the commander locks?

Every door is locked without blindness, I press the control when opening, all other doors are opened.

When the lock is opened normally, the driver's door does not happen very often.
