I’m skeptical that there would be any such small key to activate a large/deep mechanism. Can you give a plausibility argument for why there would be?
Not really, because I don’t think it’s that likely to exist. There are other routes much more likely to work though. There’s a bit of plausibility to me, mainly because of the existence of hormones, and generally the existence of genomic regulatory networks.
Why wouldn’t we have evolved to have the key trigger naturally sometimes?

We do; they’re active in childhood. I think.
