This could mean that your "new" batteries aren't as new as you think. The remotes will exhibit all sorts of strange behavior when the batteries are low.

You might try removing the batteries for a few minutes and re-installing them.

The expiration date is like 2025.

That typically means that they are already three to five years old. The dates are handy but I wouldn't hang my hat on them.

What does that do that makes the remote controller work again by removing the batteries then reinstalling after this timeframe?

It gives the electronics a chance to drain any damaging voltages before it gets re-powered. Think of a quick swap kind of like a brown-out where the voltage drops to levels that makes the remote unstable enough to lose its mind.

It's applicable only to Smart Remotes !

Can you name a DISH remote isn't a smart remote?

The remote controller has been working great since I sent the last reply here.

So allowing the remote to clear its cobwebs by taking the batteries out for a minute fixed your issue?
