Sorry no help here.... . But on the flip side, I'd give anything to get mine to STOP working. It's in the habit of starting the Jeep remotely in the middle of the night when I'm dead asleep..... LOL

If you needed to replace the Aux Battery, then the Main Battery is due for replacement. The average life expectancy is about three years.

If the voltage level drops low enough, Remote Start will not work. There may be enough in the batteries to start the engine, but the monitoring system has fixed limits.

Just replaced both main and aux this past weekend. Factory batteries lasted a little bit over 2 years on both my JT and JL. No remote start in the mornings and Aux switches temporarily unavailable warning on dash. My JL left me stranded all day in 100+ weather so I learned my lesson and acted quickly with the JT.

I thought the same thing about the low battery. Even a CEL would cause it not to remote start. Don't know if a pending cel will prevent a remote start. Got to scan to see a pending code.

Pretty much spot on sadly, my aux battery went out, shortly after my main went south as well!

Battery is #1 thing to check. If main battery is ok, still check the aux battery. A bad aux battery will mess up all kinds of things on your jeep.

#2. Is this the first time you have tried remote start after putting your doors back on. There are all kinds of threads on here about bent pins in the door connection. I had a bent pin and the jeep recognized it as having the doors off. The remote start does not work when the doors are off.

So, if it is not the aux battery it may be bent pins if you take your doors off.

Good luck.

My bet would be just a weak battery due to the cold temperatures. A good test would be to toss a charger on it and try the remote start again. If it works then, plans could be made to address the batteries.

Same thing happened to me about a week ago. After several days with no remote start, it just wouldn't start at all. Took it into the dealership and they tested and replaced both batteries. 2023 with 16K miles; not even a year and a half old...

If you park on a hill watch your Gas Level - below a certain level the remote start will not work - this has been a pain for me cause on level ground I show a bit over a 1/4 of a tank but parked on my hilly driveway I show below 1/4 of a tank and the remote start will not work.
