The passenger side door will occasionally lock on its own, causing the other doors to lock as well. I can also cause this to happen if I bang on that door, (and only that door). I also noticed that the slighted push on the door knob of that particular door, will also cause the door to lock.

What is the most likely cause of this problem?

Thanks
