My old key used to charge itself and I never considered having to change the battery in the fob. Can someone figure out how to get rid of all the key crap and wire in an old school toggle switch...

Just curious. Do you guys get notified if the word "key" or"fob" is posted on this website?

Lol, there aren't any 2017 JLs.

I'm rounding up. I got my JL in Feb 2018 so it's ALMOST 5 years.

interestingly, i had just ordered replacement batts when this thread came up.

i have noticed that now that i've had my rig approx 2 years that the range on the Remote Start was getting down to under a few hundred yards, whereas when everything was fresh it was much more.

(FWIW, i've always kept my fobs in a little RF-proof storage when at home.)

Keeping that spare battery in the jeep, with all that heat will kill it's shelf life. Usually, the Fob will start acting up, by saying it isn't being detected, intermittently, before the battery totally dies.

Or in the cold will deplete the extra batteries.

As per the owners manual, you can start the jeep using the fob to push the start button if the battery dies.

Have had to do this when the fob battery was so cold it would not function and it works perfectly. Had a bit of anxiety once when for the same reason the fob would not unlock the doors... until i remembered the key. How could i forget about the key when it always seems to want to deploy like a spring-loaded jackknife?! LOL

I've never seen the 'fob has left the vehicle' warning and it died last week. I couldn't start it by pressing the fob on the switch either, but I may have been using the wrong end ?!?. Anyway.....I had the spare fob in the house. Battery now changed out. All good !

Undoubtedly, you used the wrong end of the fob... or you did not have your foot pushed down firmly on the brake pedal when you were pushing the correct fob end firmly into/on the start button.

As for Evic message, key fob has left the vehicle or message indicating battery on fob is a muck is not always lets say a given. You may not see such a message.

For your own edification, do consider removing the battery from the fob that you originally tried and try again to start your JL, doing as I just mentioned..

Great idea. I'll try removing the battery and see if I can get it to start. Thanks a lot !

I just had my first TPMS battery die tonight, ever. On anything. 8 years old. On a 2014.
