Are you tired of switching between your Vizio remote and your cable box remote? By programming your Vizio universal remote to control your cable box, you can finally put one of those remotes away. This guide is designed to make that process simple by providing verified codes and clear, easy-to-follow instructions.
Important Note: This process is for Vizio universal remotes (like the XRU-series) or TVs that came with a remote featuring a universal function. A standard, basic Vizio TV remote without SETUP or device buttons (CBL, SAT, etc.) cannot be programmed to control other devices.
Verified Codes for Major Cable Box Brands
Finding the correct code can be the most frustrating part of the process. To build your trust and save you time, we have compiled a list of the most frequently successful codes, organized by the major US cable providers. Find your provider in the table and try the codes in the order listed.

How to Program Your Vizio Remote with a Cable Box Code
Once you have the first code for your provider, the setup process takes less than a minute.
- Turn on your cable box and Vizio TV.
- On your Vizio universal remote, press and hold the SETUP button until the remote’s LED indicator turns on.
- Press the CBL or CABLE button. The LED light should remain lit.
- Enter the first 4-digit code from the table above using the number pad.
- If the code is correct, the LED indicator will blink twice and then turn off.
- Aim the remote at your cable box and try to change the channel. If it works, the setup is complete!
If the first code doesn’t work, don’t worry. Simply repeat steps 2-4 with the next code on the list for your provider.
What If None of the Codes Work?
If you have tried all the codes for your brand without success, your remote’s built-in “auto-code search” is your best next step. This feature scans through the remote’s entire code library to find a match. The exact steps are outlined in our main Vizio universal remote programming guide.
If at any point your remote becomes completely unresponsive, it may have a glitch that a quick reset will solve. You can learn this simple fix in our guide on how to reset any Vizio remote.
A Note on Modern TVs and HDMI-CEC
On some very new Vizio Smart TVs, you may not need to program the remote at all. A feature called HDMI-CEC can sometimes allow your Vizio TV remote to automatically send commands to your cable box through the HDMI cable. Check your TV’s settings under System > CEC and ensure the feature is enabled.
Conclusion
Programming your Vizio universal remote to control your cable box is the best way to reduce clutter and simplify your daily viewing. By using our brand-specific code list to find a verified starting point, you can avoid the frustration of random guessing. This quick setup process will leave you with a single, powerful remote for your entire system.
