How to rest Ford Expedition sync 2012?

Last week I put made my iPhone to forget SYNC by accident and now it just say Carkit. I couldn't connect because i need the password and I don't have it. So how do I rest SYNC settings and re do it again from the beginning. My car is 2012 Expedition XLT with out navigation system

This makes no sense whatsoever. None. Zero. Nada. As a matter of safety I put my cell phone to OFF when driving. Should I forget and it rings, I ignore it until I get to where I'm going. Just yesterday, the person I was following, swerved into the next lane due to this lack of attention. Luckily he did not drift into the opposite lane as there were cars there. But what you ask is not comprehensible.
