Will EasySocial Invisible Recaptcha also work with my Komento and EasyBlog

I am thinking to convert to the Invisible ReCAPTCHA for EasySocial now and wonder if I would then be using a different ReCAPTCHA for EasyBlog and Komento on the same site then?

Also, if I apply for an invisible ReCAPTCHA key will that invalidate my current ReCAPTCHA key? I am using version 2 of ReCAPTCHA.
