Will I get any type of warning before the
battery dies in my 2014 Escape Titanium
keyless entry fob?
Wow, maybe replace the battery in the FOB every 2 or 3 years and not worry about it.
The fob uses a button battery. I can't swear to this but I think the battery will get weaker before it dies, and if true, you will note it becomes more & more difficult to give it commands as you move further away from the car. The batteries aren't expensive so if you start to feel it getting weak, I'd advise replacing it.
Yes warning will come up in instrument cluster saying key fob low battery on that car
