Damaged keyfob could be drawing incorrect current under load which will cause incorrect voltage values under load. But 2 of us already put in new batteries and it didn't solve the issue. More like a damaged board on the remote. Strangely it has only fell 1-2 times where as my old Dodge Dart fell every other day and had no issues.
I am leaning to believe the keyfob is damaged. While it's just a minor annoyance, suggesting a battery swap is not the correct answer. I'll do some more investigation, but so far this mostly happens with comfort access and rarely when unlocking from the button. |

All of that does not mean that your keyfob is not at fault. Just it seems unlikely to me that it would fail so easily. I accidently washed one of mine, kicked it down the steps, my little son got a hold of it....and its still working. Just saying , before you go the expensive route, you might want to try exact replacement battery - in my case it was Sony. On a different note, BG as in the country alakazam or am I misreading it? |

Bulgaria, yes. I'll get an exact Sony battery at some point. But the second keyfob doesn't display the issue. Either way, working on it.

I had the same issue. Got the warning, changed battery (took from spare fob).
Still got warning. Found other thread that stated that fob sends voltage info to car and needs 5 consecutive "ok voltage interactions" before the message disappears. So, I realized that I had probably only interacted 2-3 times when googling the problem. Went down to car, clicked lock/unlock a couple of times and then no more error message. |

Went to do some shopping and waited for the car to go to sleep. You only need around 15mins after locking. I came back and before doing anything else, I used the remote to unlock and relock the car, not with the comfort access but rather using the Keyfobs buttons. I did this 3 or 4 times. After that the problems went away. Never came back. |

This reminds me that I should see if I can get them to replace my 12v battery while I'm still under warranty and pre paid maintenance coverage for free rather then buying and registering a new battery myself. I have been using a maintainer though not consistently. Those things do work as I use one to maintain the battery on my other car and it has lasted twice as long as any battery in that car before I used a maintainer.

My fob battery was replaced by the technician at the 2nd service, I was not having any issues with it nor did I request a replacement. Kinda was a nice surprise when I checked the service invoice and saw that the battery had been replaced. I would have brought in my other key (wife using it) had I known.

They'll swap out the fob batteries under the service plan, they only cost a couple of dollars. They're not going to swap out the car battery for no charge unless it's dead within the warranty period for it.

Those fob batteries are pretty expensive at my dealership - they wanted $35 to swap it out. I bought a new battery for a few dollars and it didn't fix the problem despite being the exact same battery.

Old battery tested (without a load, so I r ealize that only goes so far...) at 3.0V, so I thought that it was ok, but no, needed to drop in a new battery with 3.3V, no fancy brand, something from China. Leaving the car for >15 mins and trying again didn't work. Don't have Comfort access, 2014 F30, BOTH fobs were operational with new batteries. Error message stubbornly remained. Finally fixed by using fob to lock/unlock 4-5 times, then all cleared and back to normal. Thought I'd share for folks that come along afterwards. |

I had this issue with mine for almost 2 months thinking it was a bad car battery and was on its way out. I replaced the batteries in the fobs twice and it still wouldn't go away so I gave up dealing with it.
I ended up buying a new pair of batteries from Walmart and what do you know? The error went away. I'm thinking the batteries I swapped in came from the same pack and had somehow gone bad? Make sure to replace both fob batteries.

This was several years ago, but I bought my batteries at a local grocery chain. I prefer name-brand batteries such as Duracell.

I second buying "real batteries". I have a ton of automation sensors that use that same CR2450 cell, so I was buying cheap ones off Amazon. They'd work for 6-12 months in these always on sensors, but would toss the "low battery" warning within a month on my fobs. Bought some energizers from Home Depot one day and it's been flawless for months now.
