Could any of the keys be used to couse sever poltergeist activity.

Are you asking if summoning an entity out of the keys will cause poltergeist activity?

You’re going to have to clarify more

What “keys” are you talking about?

enochian keys like which one can be used to curse with poltergeist

Well, the Enochian keys aren’t meant for that type of purpose, so there is no specific key to cause poltergeist activity.

The only thing I can recommend is to experiment with each one and find out for yourself.
