おかなきゃ

Any explanation of what this means/does to the sentence? I see it usually at the end of a verb in te form. I came across it as 空けておかなきゃ. The only reference I have found is some Ranma lyrics: Moraeru mon' wa moratte okanakya. I gotta receive what I can receive. Not that it really helps me...

Wait, is it perhaps Oku, "got to/must do/have to"? but is just in some casual/slang form? If so, what is the negative "okanakya" form? Is there a difference between nakya and nakyanaranai? Is one the negative?

It looks like it means have to make space/room.

I think the ーなくちゃ form contracts from なくては while なきゃ is a contraction of 無ければならない・なければいけない. And yes, most people just end up with なきゃ by omitting the ならない/いけない/だめ....

なきゃ is a contraction of なければ, not of the full なければならない. As you said in your following sentence, the ならない is often omitted, but it's not involved in the contraction.

おかなきゃ is the contraction of おかなければ, as already explained, but the verb おく or おかなきゃ itself doesn't have such a meaning. "-Te form of verb + おかなきゃ(ならない/いけない)" can mean "must/have (got) to do in advance."

With the verbs :
おく oku: It means "to do in advance". お弁当を作っておいた obentō o tsukutte oita: "I've made a boxed lunch (for later)". Colloquially, in this form the "e" often disappears, so 作っておいた tsukutte oita becomes 作っといた tsukuttoita.
