The five-digit Comcast remote codes are found in the Comcast's "Universal Remote User Guide." The actual code varies depending on the brand of television set.
The first step in programming the remote is to locate the five-digit code in the User Guide. The consumer should first turn on the TV then press the remote's TV button. Then the "Setup" button should be pressed and held until the TV button flashes two times. The consumer should then enter the five-digit code that was found in the User Guide. The TV button will flash two times if it is the right code. The code should be written down in a safe place for future reference.
If the User Guide is not available, the consumer can use the built-in code search function on the remote. To do this, manually turn on the TV, then press the "TV" button on the remote. Next, the consumer needs to press and hold the "Setup" button until the "TV" button flashes two times. The numbers 911 should then be entered. The "TV" button will flash twice, then the number 1 should be pressed. The "TV" button will flash two times again. The consumer then needs to press the "Power" button and the "Channel Up" button until the TV turns off. Then, press "Setup" to lock the code in.
