Hope someone can help, since two Ford dealerships have thrown up their hands and said, "I don't know how to fix this."

Yesterday, when I got in my car (it has 42M on it and is almost 3 years old), it said my Key Battery was low. I stopped at Interstate Battery and they figured out how to replace both FOB button batteries (with help from a YouTube video). Unfortunately, the message is still coming up when I start the car. I even removed the round steering stalk plastic piece and stuck my FOB directly inside (2nd dealership said to try this since it possibly could help reset itself if it was inserted directly). Two stops and starts later, the message is still there. The car starts fine. Doors unlock fine. No driveability problems. Is there ANY way to reset this message to make it go away (like the oil change reset sequence that I occasionally perform, for instance)? Both dealerships said if I brought the car in, they "could take a look." Read...CHARGE ME $$ for trying a bunch of things.

I may be a woman, but I am very computer savvy and can follow reasonable instructions. I do my own MyFord Touch updates without help. I can navigate my car's gizmos without any issue. The guy at the dealership also insinuated that my iPhone could be the culprit. Huh? I connect it ALL the time when I'm in the car, and this has never been an issue.

So, with that, can anyone give me some simple advice or am I stuck spending my hard-earned money having some dude scratch his head for a few hours?

Thanks!

What settings will I lose on MyFord Touch by doing this? I have a lot of customized Sirius stations, Alerts for songs, custom wallpaper, etc. how long does the battery have to be disconnected? Thx.

Not sure what youd lose but those fob batteries have been known to not always be sold with a full charge. You could also attempt replacing your fob battery with another new one. Walmart sells 2 packs of them for $4 in the watch section.

Kabigon--How long did it take for the message to eventually disappear on your car? Looks like you have the same make/model as my Focus. So far, it's been four days and the message is still displaying each time I start the car. The batteries that were installed were fresh 10-year expiration date batteries, so I'm not concerned that they were past their shelf life. Both FOBs give me the same message. Disconnecting the battery seems like a slipshod way to accomplish something, in my opinion.

OP! Try going into the information menu on your thumb menu and into system status. I think you can reset it from there. You might have to hold the ok button to reset it. I'm not by my car or I'd check.

Bad advice. Never "reset the computer" arbitrarily.
When does the error go away then if it doesn't turn off with a new battery? That's been the advice given by others who've had the same issue after changing the battery with no change in status.

E.x.

Since changing the batteries in the keyfobs didn't get rid of the message, I decided to disconnect the battery yesterday. I disconnected the positive terminal for a couple of minutes and then reconnected it. The message is now gone and everything is working correctly.
I haven't had this issue yet however.

I'm telling you get a new battery. I've known a number of people to buy these without a full charge or defective. Expiration/shelf life doesn't always mean it's a good battery.

I believe it took about 1 week.
At first, I was scratching my head but I decided to give it some time and see what happens.
I imagine that there may be a way to reset it (other than disconnecting the battery) but I didn't bother to research it.

Please read my previous reply.

I really don't like resetting all of the modules (especially the PCM) unless there is a compelling reason to do so.

Another alternative would be to pull the fuse for the module that needs resetting (i.e. MFT/Sync reset).

Pulling fuses didn't seem to work on my car for resetting the MFT, it would remove power from the affected sub-system and possibly cause it to reboot, however apart from one time when it seemed to forget the drive it was still not reset and went right back to the previous track after the crash. The fix then was to take a different USB drive when the original one that worked fine in the car with the basic sync system failed to index and caused MFT to go into a seizure/ reboot loop every time it was used.

Just copy and pasted the files onto a clean drive and it worked, some how the original one went bad even though the drive was fine.

I don't really like the idea of pulling the battery either, but that was something that works, and speeds up the process at the expense of potentially losing some of the keep alive memory for other systems you'd prefer not to reset.

Hey, everyone!

I just want to jump in real quick with a few things. I do not recommend a battery pull (on your vehicle) unless it is advised or done by your dealer. Also SYNC/MFT is not tied in to Intelligent Access Key (IAK), so a fuse pull for SYNC is not needed. For questions or issues with IAK, please shoot a private message over to Todd. Here's the link to his profile:

Hope you're all having a great week!

I had the same problem occur on my 2011 C-Max Titanium last weekend, and after replacing the batteries in the key remote, the error message remained.

I took my car into my local Ford dealer and they ended up having to carry out a BCM software update. This cleared the alarm issue.

If your key fob battery needs changing there is no need to go to the dealer to reset the message on the trip computer.you just use the arrow keys on the steering wheel and navigate to the information menu -->system status and press the ok button to reset.

Resetting MFT/Sync was simply used as an example of resetting a module.

It was not stated or implied that Sync and the IAK are somehow tied together.
I was just clarifying for the people that didn't know that, Kabigon.

Same thing happened to me, about a week as well.
