Key Battery Low again

About 4 months ago after owning my GC for 14months I got the “Key Battery Low” message. I bought 2 batteries to keep in the glovebox. Yesterday I got the message again. Weird – only 4 months use but OK. I replace the battery and life goes on. This morning I got the message AGAIN. 1 day later, brand new Energizer battery. The key sat in my loose jacket pocket for 30min after I replaced the battery, then hung on a hook until this morning. I’m wondering if something could be wrong with the key fob. Has anyone had their fob replaced due to battery issues?

Re: Key Battery Low again

My fob hangs on a hook in our laundry room only 10 feet from the vehicle. OEM battery lasted 1 1/2 years. You probably have some old or improperly stored batteries. BTW, my replacement battery was kept in my glove box too.

Re: Key Battery Low again

Maybe you're getting a bad battery connection.

Re: Key Battery Low again

Quite often it is not the battery it's the connection. Clean them good. Use a rubber eraser and pry up the bottom connector slightly to make a better connection. I had the same issue with the challenger FOBIC. Try thit first.

Re: Key Battery Low again

I scrubbed all the contacts (including the battery) with an alcohol wipe and used the same 1 day old battery and it seems to work again. If I get the message again I'll do the eraser thing + another fresh battery purchased from a different store.

OK here we go...... I had the low battery issue about a year ago. When I replaced the battery I only got a few days out of it and got the low battery message again. So I used my spare key but a few days later it also was low. So I bought two more new batteries and replaced both fobs and have not had any trouble since. I know the initial battery I purchased could have been bad, and my spare was sitting around unused for over a year so it may have been low as well. There have been several posts with a similar issue as mine, so I just makes me wonder if replacing both batteries will solve this problem.

If you use a rubber eraser, when you get done, use a small bit of alcohol or other non-plastic solvent plus compressed air to remove every bit of rubber particles and film from the fob. Rubber works, but leaves behind sulfur compounds that tend to be corrosive to electronics.

There are non-corrosive soft rubberlike cleaners, but with Radio Shack closing all those stores...

A Zeiss or similar eye glass cleaning pad held against the contacts with something soft works pretty good as well.

Careful not to remove any plating, but try to remove anything that looks even the slightest bit of discoloration.

Re: Key Battery Low again

So my cleaning made the battery last for another week or so, then the message came up again yesterday. In goes another new battery - different brand. (3rd one in less than a month) This morning - key battery low message again.

So before I go to the dealer, let me ask a few things:
  • Does anyone know the minimum voltage required so I can test the battery?
  • I assume this is likely either (A) the key is mis-sensing the voltage or (B) the key is draining batteries due to some kind of electronics failure. Can either of these be tested somehow?
  • If I go to the dealer with this, I assume they will just throw a fresh battery in and send me away. How can they possibly test for this?

This seems to have worked. At first I didn't see how a FOB that wasn't even in the vehicle could be the problem but the spare / wife's key was either close enough to send a signal or the Jeep remembered that it's battery was low the t last time it was in the vehicle. Replaced both 2 weeks ago - so far so good.

Re: Key Battery Low again

this is crazy... my 2011 batteries / fobs lasted the whole 3 years we had it. In fact, Ive only ever had to replace 1 fob battery. My 2005 scion key fobs both are still on the original batteries.

Re: Key Battery Low again

What brand of batteries are these that keep dying on people? Can other brands be bought for our FOBs instead?

Unhappy Re: Key Battery Low again

Having similar problems with both my key fobs. When I initially got my vehicle the battery lasted about 4 months. Now they only last about a month or two before failing. Have made sure the contacts are good must be something else wrong with the fobs. I will try a different batch of battery when my last spare fails.
