Welcome and you probably need a new battery.

Will the battery go dead in the key fob if you leave it in the car?

No it won't go dead if you leave it in the car. I think recommends changing it at every 10k service interval.

Don't worry, I got my car since 2007, I only changed the key fob's battery only once. Which reminds me, I think I should get new batteries for myself. lol.
