my daughter has disabled her phone, her apple account is on my family sharing and I am the organizer.

My daughter got an IPHONE for christmas yesterday and she has disabled the lock screen be reentering the wrong access code unlock the home screen.

I am the organizer on our family account and I am unable to find access to reverse this from either my phone or hers.

I have now connected to our PC and logged into itunes but yet I am still unable to pin point where I should be hooked into for this issue to be resolved.
