Wow, this is gonna be a pretty late reply, but I have to disagree about the whole "it took love" part. I personally interpreted it as "it took a reminder". I mean it's kinda corny when I say it that way, but what I mean is that the key wasn't really a representation of love, but rather identity. Even when Jackson's high on wolfsbane-laced punch, he has nightmarish hallucinations of his parents without faces, which suggested that he himself thought had no identity to a degree. Lydia giving Jackson the key, in my opinion, reminded him that he did have an impact on someone and that he was Jackson the human when he did so, not someone without an identy.
