If it's the COX remote... Turn on the device you wanna program like the tv, take the COX remote, PRESS & HOLD MUTE & SELECT, UNTIL ONE OF THE BUTTONS AT THE TOP BLINKS TWICE, RELEASE BOTH BUTTONS, PRESS THE TV BUTTON, (IT may stay lit) PRESS & HOLD SELECT UNTIL THE DEVICE POWERS OFF... YOUR REMOTE SHOULD WORK AFTER THAT.
Call Cox up and they will take you step by step
You could also call Cox and they would talk you through it.
Go to YouTube and put in how to program a Cox remote and ull should be fine
