I went out in the car tonight and the drivers rear passenger side door won’t open from the outside. I usually put my walking stick and bag on the back seat. I think I might have caught the button that locks all the doors? I don’t know though because the door at the back nearside still opens. Maybe it needs oiling? Or maybe if I leave the window down and try leaning in from the outside I could get it open? I will try and ring a friend for advice.
