may be replacing one key fob battery

the key fob I use all the time seems to be less powerful. meaning I can't always start it from my front door anymore, or even as I walk to the car! while my backup still works just fine. thinking this battery can use replacing. make sense? anyone do it? quick & easy? painful & expensive?

Hopefully yours is just the battery. I've noticed both of mine are fairly intermittent. Sometimes it'll work, other times I can stand beside the car and nothing happens (with a new battery in the remote). I can hammer the buttons and eventually it'll start responding again after maybe 10-20 seconds of nothing. I havent bothered taking it in, just chalked it up to be possible interference or maybe the Jeep just doesn't like me.

My personal experience with Key Fobs for cars with Keyless Entry/Keyless Go (push button and/or remote start) is to expect annual battery replacement. The fob is basically "awake" most of the time and more so when it is near or inside the car. I have not replaced the one on my KL but did it a few times with my previous GC and as others said, replacement is fairly easy.

Instead of being alarmed not being able to open or start the car, I decided to put in a reminder on my calendar to replace the batteries every year, instead of waiting for the batteries to fail.

Prying apart the fob is a bit easier (and won't damage the plastic) if you use a plastic trim tool.

I bought this set from Amazon, it has paid for itself many times over.

not working again. well, finicky. I can lock or unlock from a distance but not remote start. took it apart & put it back together, then remote start worked but couldn't turn it off from a distance (not that I ever knew how). might try another new battery & might use the other fob as my main one & keep this one as the backup
