I did a search and came up with a lot of info about the key fobs, but nothing regarding getting an EVIC message stating fob battery is low, and especially not at 2000 miles.

So, does anyone have some sort of explanation as to why im being told the fob batter is low on my 2 month old Jeep with 2,000 miles? No other issues whatsoever. Please tell me I dont have to replace fob batteries every 2 months. Never had to with other cars of mine that has keyless access and push start.

Thanks,
James

James -

It's possible the keys are packed in the owners manual pack (assuming we recevied manuals) and a button may have been pushed and drained the battery. Hearing all the horror stories about the keyless entry, I replaced both fobs batteries when we took delivery. It uses CR2032 and they are cheap. Our Jeep is a year old and I'll replace them again, just for good measure.

Ok so I never got the low fob battery message again, but after I got home from work and parked the Jeep in the garage my rear glass popped open on its own. I thought thats weird considering I dont think you can even do that from the fob. So I close it and a couple minutes later it does it again. WTF. So I removed the battery from my original fob and am using the spare thats been sitting in my junk drawer. We will see what happens. I wonder if the battery really was low and maybe that can trigger the Jeep to do really weird things?
Anyone else experience things like this?

UPDATE: Well so far since removing the battery from my original fob the rear hatch has not automatically popped. So hopefully its nothing more than a weak battery in the fob. I will keep my fingers crossed.

You might have a sticky button that is draining the fob and might explain the random glass pop opens.

It's possible the last time you replaced the battery that it shifted the board just enough to un-stick the button.

It's a transmitter, so it uses battery power. The more powerful (longer range) the transmitter, the more battery power it uses. Since the range for the remote start is 300', that's a lot more power than the typical door opener fob. So if you use that function a lot, expect to replace the battery a lot more often.

So far no issues after replacing the battery on that fob. Its weird that it was low already considering I rarely even touch my key fob, but either way as long as nothings wrong with the car im fine with it.

Being a new car you don't know how long the battery has been in the remote for, perhaps it was installed 2 years ago and sitting in Jefferson awaiting a car to mate with. and it was on a boat for a few months before that, only real way to tell is to record when you changed the battery out and go from there.

Tried to replace my key fob battery but can't open the case. I removed the mechanical key first and used a broad head screwdriver to try and separate the halfs and was afraid I was going to break something. Is this the way to replace the battery? The manual made no mention of replacing the battery in the key section around page 14. I have a 2012 GJ Overland V8.

Yes, I just did mine this past weekend. Removed the key, then took a wide-flat-bladed screwdriver into the open slot where the key was and twisted. A little disconcerting, but it did pop open with quite a bit of force. Take some time to clean the case and rubber button insert with a damp cloth - I could not believe the amount of dirt and lint in there for a FOB that stays in my pocket 99% of the time. It took a little effort to snap the case back together. Best luck.

Thanks Justal - a little premature on my part - saw a YouTube and realized I was putting the screwdriver a little off where it should go. Everything worked out - it is tight though. Since I keep my key in my truck a lot since spring purchase decided to put in a new one just to establish a baseline. Locking the driver door via the door button when I get out takes a bit to respond sometimes so thought maybe my battery was down. Otherwise everything has worked fine.

Just had both of mine go out at the same time...I think? My main daily was showing the EVIC notice fob battery low...then I pulled my 2nd out of "storage" only to get the same notice. Is that from the firat/daily key? Or did both go low at similar times. They are 2.5 years old, with one getting 99% of the use. I'm on a trip now so I grabbed the 2nd thinking it would be fine, but the note is still there. Just replaced the battery C2032 tonight and will report back if they went out at the same time or its similar to a code that throws and stays? To me it should be key-dependent...old thread but still relevant! Thanks for posting the fob battery number and info

Side note...I have a different black leather with red stitching setup on my daily (other) key...so went with a silicone case and hook chain (both AMaxon specials)...love clipping it to my belt loop as it doesn't hang down and will never lose it :thumbsup:

08Hemi,

If your fob still is not working after the battery replacement, feel free to PM your VIN so I can look into this for you.

Wondering if 08Hemi's problem was resolved, and, if so, what resolved it.

A friend with a 2014 WK2 has the same or similar problem. Tried both key fobs and had new batteries in both, and still the same message (and no start).
