My roommate has a comcast box in his room and a habit of renting movies but not paying for them. I pay for Comcast XI TV, cable and voice service. I cannot access the box to set up a purchase pin. Can I do this remotely online?
login your account at https://secure.xfinity.com > Settings > Parental Control
then you can reset your Parental Control and Purchase PINs in all set-top boxes you have.
