And there's not a whole lot of combinations to try...
This is not that simple since:
1)
keycaptcha's "coorect" places (coordinates) are never repeated even for the same captcha;
2)
keycaptchas are shown randomly from a set of many captchas;
3)
captchas are constantly being changed by KeyCAPTCHA devs;
3a)
keycaptcha.com site has online designer for subscribers of "Personal KeyCAPTCHA" (5 USD per month or 20 a year) account to create (any number of) their own captchas from their own images. Hardly someone would bother to create a bot to crack just for one site
If to use pre-built basic set of (ready) keycaptchas, this service is free.
4)
etc.
