doors do not lock

Slm. The doors of my 2010 model Peugeot 206+ are not locked with a remote control or direct key. There is no problem in locking after going for a while, but according to the availability of the parking lot, the vehicle does not only lock in the rear doors or four doors after the location has been changed. Only the tailgate is locked. Masters could not find a solution
I would be glad if you have help with knowledge. Respects.

This situation came to the press the other day. I have a Quiksilver ... throwing it back when I lock it from the control ... I went to the lockers, brought the lock on the door on the edge of the door forward, some problem improved, there was a gap in the door ... even when I entered the hole, the door was giving an open warning ...
