Mondeo door won't lock

I have a problem with one door. If I lock the car three doors will be locked but the rear right passenger door is unlocked. I have tried it manually also but no use. Still remains the same problem.

Can you tell how to fix please or atleast what the problem is?

Gummed up lock servo. Might free up with some lubricant. Will mean removing the door panel to gat at it.
