They are about to leave together when the door won't open.

The door will open one day, when you are strong enough to turn the key.

As I was getting out of my car, the front door opened.

I don't know what we would have said, but just then the door opened.

A door opened at the far end of the room.

The next thing I knew, however, the front door opened again and he came out.

A moment later, the door opened and they went inside.

The door of the room had opened while the two men were talking.

We were almost to the house when the door opened.

The door opened, and someone came in from the night.
