Xfinity Service Cable Card UnPair/Re-Pair

  Hi,

  I understand that cable card support is limited.  I tried the website to re-pair one of my cablecards, but it fails every time I've tried.  Calls into service were met with the equivalent of a blank stare, and eventually a response of "we don't support that anymore", even though my cablecards remain on my account.  I'd appreciate some help getting to someone who knows how to re-pair a card.  I have all the relevant information to do so. 

Thanks.

Hello bfaz18 thanks so much for taking the time to reach out here via our Xfinity Forums with these CableCARD pairing questions!  

 

When trying to re-pair the CableCARD, what errors are you seeing? We have an amazing article that goes in-depth on pairing and activating CableCARDs

 

Pair or Activate Your CableCARD — Self-installation Setup

 

Have you had a chance to check this article out?

Thanks for replying.  Yes, I've read that article.  when I try to activate using the website, I get through, the acct number/phone number prompt and I get taken to the page which lists all of my cable cards, including the one that requires re-pairing.  I select it, add the hostid and unit data which I get from the Tivo's installation menu - the host id is the same as what's listed on the website, but the unit data is different ( because it's a new hard drive - the previous drive failed completely ), then submit.  The message that is get is approximately, "the operation failed", which leaves me with no path to follow.  I thought perhaps that it was because the hostid was the same as what it already had, but I tried with a different Tivo that I'd be ok with using, but I received the exact same result.  I then thought that perhaps a un-pairing would help, but I can't do that from the website.  

The result of all this is that I suspect that one of the few remaining cable card experts at Comcast might be able to help, but I have no path forward on my own.

Thanks.
