How to Unlock a Comcast Cable Box

By Maya Austen

To control which cable content is readily accessible to your home, use your Comcast box's parental control locks to block certain content. The parental control can be used to restrict content based on rating, lock out entire channels or block and even hide specific show titles. When the locks are in place, only persons who know the pin number for the Comcast box are able to access blocked programming. If you find these locks to be cumbersome, you can remove them, either permanently or temporarily. You can even erase the PIN number.
