A key was turning in the lock of the door.

Until the key turned, the door opened - and I fell through.

No matter what I do the key will not turn in the ignition.

Instead, he slammed the door, turned a key in the lock.

The door shut, and an instant later the key turned.

The key at last slipped into its slot and turned.

After a moment the key turned and she came out.

A minute went by, and then the key turned very quietly in the lock.

The small key turned easily, and the lid came up.

The door shut, the key turned, the steps went away.
