I don't see the point in giving back the key just because she's moving next door. It would make more sense to give a copy of her unit's key.. At least that way, they can just go next door any time they need/want to. It would be more convenient that way.

That is literally what she did. Hence why Kiyose says "this isn't the key to my place".

its confusing since the key and strap are drawn exactly the same but yeah they gave each other a copy of their key. they should've just moved in together :P
