Can't enter some of the remote codes listed

[XorCist]

Hello, I just got DirecTV installed. I have a Westinghouse EW32S5KW connected to one of the boxes, and when I go to program the remote, some of the codes listed on the screen, won't enter. When I go to push in the last digit it'll flash red. The ones that do enter, don't work. I have the RC73 remote.
Thanks!

The data base of codes on the receivers are for the RC6x seriee remotes. The RC7x don't have that many codes on board as they were made to be loaded by a compatible receiver.

What model of receiver do you have?

Then put the remote on RF by pressing and holding MUTE and SELECT for a few seconds. Then follow the on screen instructions.
