Jeep door wont open with the key

Is this FOB failure (RKE)
or metal key failure.
say what you do. exactly.
or if 2nd key that came with car fails too....???
and what all doors do. not just one...
the metal key works but the fob button fails
is that it?
the car have only one key is bad.
but if true the battery may fix it.
on older cars, 7 years use, we clean the fob button contacts too.
with pure alcohol.

It could be the battery on your key fob needs replacing. Bring it to Walmart or any auto parts store.

Make sure you have the right key. Check and see if it works in another door or the rear hatch. If it works you could have something rusted or sticking. Does it go all the way in? Will it turn freely both ways? If so then something could be broken inside. If it does not go all the way in or sticks try spraying some WD40 or rust out, or penetrating oil into the key slot. If that does still not work you will have to take the inside door panel off. Hope this helps.
