Hi, Cheri Torres with DISH Network Customer Service here. I came across your post and wanted to see if I could help. We have a few different codes for each of our different models of remotes. You will be able to locate the model of your remote on the back of the remote at the top usually a two to three digit number with a decimal point. I will list here for you the best codes for our more popular models of remotes. I hope you find these codes and instructions useful and if you have any further questions or concerns feel free to email me at [email protected].
