This answer is Let the door be opened.

Are such a question and answer natural?

Let the door be opened is grammatical. Nobody would ever say it except in jest.

The same applies to many of these active-to-passive exercises. Don't waste your time on them.

Great comment. I feel that I am a ghost when I am asked such a question.

Note my corrections above, particularly to the order of the post. I agree wholeheartedly with the others - don't bother with active to passive exercises. They are a waste of your time. You only need to be able to recognise the passive when you see it, and that's generally easy - if you can add "by zombies" to the end of the sentence, it's probably passive.

We've certainly told someone (I can't remember if it's you) multiple times to stop using Facebook to learn English.

Also, I find the idea of transforming an imperative into the passive utterly pointless. An imperative is intended to be said directly to the person someone is ordering to do something.

I'd say that, semantically, the following is closer to being a passive of "Open the door":

You are hereby commanded (by me) to open the door.
