remote control low battery warning
I received the dash pop-up last week about changing remote control battery. Everything works fine, but I assume it's just passed the threshold. I had to order the 2450 lithium cell, so swapped with my 2nd (never used) fob battery -- still had the message.
The new batteries arrived yesterday, and I replaced on both fobs -- but the car STILL says low battery. The are comfort access, so should not need any reprogramming. I searched forums already, but can't find if the code needs a reset. Any thoughts? Thanks. |

Did you try holding the fob close to the steering wheel "hold key here" sensor?

Knowing there is nothing to reprogram or reset, it must just be something simple. Thanks! |

Duracell batteries are now made by Varta, the German battery company. So, I think the new batteries are fine. Again I'd drive the car for a week and see if the warning goes away.

Curious what the battery life in the FOB typically is. I received the warning in April and replaced the battery, just got another warning for the same fob yesterday. I would think battery should last longer than 6 months. Car is not driven daily either.
Thx, Don |

The battery in one of my fobs for my 2018 was replaced by the dealer when I took my car in for its annual service in 2021 even though there was no low battery warning. The other fob did get a warning a few months later. Overall, it looks like the batteries seem to last about 3 years for me.

I’ve done one replacement of the remote batteries on our 2017 car, about 3 years from delivery, too.
Old stock or batteries of unknown quality could be a cause of a short battery life. |
