1. Which iPad? Mini, Air, Pro...?
2. Are you talking about a full sized Apple keyboard or a different one? (Unsure how you'd "roll" a keyboard out)
2B. Assuming no neoprene cases?
3. Can't you look at the old case and order it again?
I'm assuming some Folio style case as at this point where the keyboard would just sit between the iPad screen and the other side of the cover of the Folio case? Possibly even a Gen 1 version since the older ones were thicker, thus allowing more room inside the folio for a keyboard?
Usually such folio cases have pad paper on the other side. You'd remove said pad and place a keyboard in place. Possibly keep it in place with a clip?
Something like this?

But unsure if dimensions would play nice with the keyboard. Also unsure if you'd need to acquire some way to keep the keyboard/iPad from breaking from repeated mashing of the keyboard keys inside the case.

This looks promising as well, maybe a bit bulky, but again, unsure of the ipad size. You'd also still need some way to protect the keyboard keys.
