Your scene shows a door closing, but the camera recording picked up voices and traffic. Find a quiet place to record several closes at different distances. Listen to the picture first: a gentle latch and a heavy slam tell different stories, even when the action looks similar.
Keep the cleanest take, trim the handling noise, and save it separately from the scene audio. When you are ready to place it against the picture, how to apply sound effects explains timing, level, and blending.
