Some universal remotes lose the programmed codes when both batteries are removed. When replacing batteries, do so one battery at a time. This ensures that there is a current running with just enough voltage to keep the stored codes from getting erased. If you’re worried you’ll forget and remove both batteries, use a label maker or paint marker to write a reminder on the inside of the battery cover.

If your device can “learn” and your other devices have remote controls, you can point the two devices at one another and use a key combination to force your universal remote to emulate the original. See your manual for information on how to start Learning Mode.
