To program your Comcast remote, acquire the manufacturer’s programming code that corresponds to your cable box or television set. Programming codes are located in the Comcast Universal Remote Control user guide.
- Locate the manufacturer's programming code
Visit the section of the Comcast Universal Remote Control user guide that corresponds to the specific make of your television. Highlight or record the codes on a separate piece of paper in the order they appear. After acquiring the codes, turn on your television, and visit a working channel with both picture and sound.
- Enter the five-digit code
On your Comcast remote, press the TV key once. Then, press and hold the Setup key until the TV key blinks twice. Following the blinks, release the Setup key, and enter the first five-digit code from the guide. If the code is valid, the TV key blinks twice. If the code is invalid, the TV key blinks once. Continue entering the codes until the device registers a valid entry.
- Access the device if necessary
If your television is not listed in the guide or you are not successful in entering a code, press TV once. Then, press and hold the Setup key until the TV key blinks twice. Release the setup key before entering 9-9-1. Press and release the 1 key, and then press Power and CH+ until your TV turns off. Once off, press Setup once to submit an IR code from the database to your device. Press power to turn your TV back on to ensure that your device is controlled by your remote.
