Dogs often don't react to things they are used to and your rattling the keys a bunch to test her has probably just inured her to them and there's no reason to react as far as she sees it. But if she comes running when you call her, squeak a toy or open her food container while she's in another room, she can likely hear just fine - she's just become selective to whom and what she responds. I'd still have the vet check her hearing and ears.
