Why is it that the door close button never works?

The Door Close button is not for you. It's for when the elevator is in an override mode, like when there's a fire, or when someone is moving something large in the elevator.

If you have the right key, you can turn the switch to a mode like "Fire" or "Independent," during which the doors do not automatically open and close. This is so the elevator can be moved to a particular floor, ignoring all of the other elevator requests, and the door only opened and closed when the keyholder wants it.

There are some building owners who configure the Door Close button to respond to pushes. But they're not common.

/I briefly worked for a large apartment complex, and had to assist people moving in and out of the buildings.
