TiVo cable cards not working

I have been an xfinity customer for YEARS. Tv and internet. I have also had 2 cable cards running in 2 TiVos for years as well. For the most part, all has worked good. I know as of Oct 2024, xfinity doesn’t support cable cards except for exisiting customers like myself.

Occasionally, I have had issues with these cable cards. Sometimes it was an easy fix (cable card hotline). Other times it required a tech visit. Either way, I was able to get the TiVos working good again.

recently, my cable cards stopped working again. It’s been about 2 weeks since I have gotten any channels on both TiVos. I haven’t changed my account for ANYTHING in years so I k ow it’s not due to that. 

since I am an exisiting customer, Is there possibly an easier way to get these cable cards working again? If so, how?
