The buttons on my current remote have begun to fail, so I decided to install the same thing on a new one. I still have the button setup from the last time.
I hooked everything up and tried to send the button set (don't remember what you call a program that's installed on the remote), and got this error message.

I did the "Remote Signature Blink Back" and both remotes give the same number 2556. What does it take to make remotes identical?
