My remote was working this past Saturday and the all of a sudden it doesn't work. I have a spare and it works.
At first I thought it was the battery but it works in the spare so it's not the battery.

What else can it be?

Open the remote and clean the contacts, use either a pencil eraser or alcohol.
My 2016 Jeep had a battery in the remote go bad in under the first two weeks of owning it and fine ever since with new battery.
Did you buy a new battery anyway, I would.

I didn't buy one but I did use a new one out of a pack I already had and tried the battery from the other remote.
I used all 3 in the spare remote and it worked with all 3. Then I tried all 3 batteries in the remote I've been using and it still didn't work with any of them.
Could the frequency change on the remote?

You probably have to to relearn the remote. It's not hard and the directions are on here somewhere.
Good luck.

Thanks Hotrod, I found it! First try I must not have timed it right but the second time I seen flashers blink, followed rest of the directions and now it works.
Here is a link to the thead, I just went by post#8.
