sync reset caused... problems.

So I know the answer is probably "dealership" but here's my hail Mary.

One day a few weeks ago, my USB ports stopped working. Both of them at the same time. Tried multiple cords and devices, nothing would connect or charge. My friend did a hard reset on Sync, USB started working again. But my key fobs stopped working immediately. Well, sort of.

I can start and drive the car just fine, but cannot lock the doors at all with either the button on the door handle or the fob. About 30% of the time I open the door, the car alarm goes off until I start the car. Initially, I could open the hatch with the fob in proximity, but now I can't. And the lock button on the dash now does not work. No light, no effect. I currently cannot lock the car or open the hatch at all.

I tried holding down both the lock and unlock buttons for at least 20 seconds on the fob while outside the car. This makes the lights flash but has no other effect.

Is there anything else I should try before I turn my car over to Ford for god knows how long, rent a shitbox for work, and start eating ramen for every meal in preparation for a huge bill? I know my particular model has the worst possible version of Sync, and the reset definitely initiated the issue.

Thanks for your help!

How old is your battery? All sorts of weird things can happen with this car when your battery is weak, and many of them don't seem like they would be related to it.
If your battery is close to 4 years older or older, I would replace it if I were you no matter how it tests out. That way you can eliminate that possible cause, and if it turns out to be something else, you were close to needing a new battery anyway.

^^^What he said, as well as replacing your key fob lithiums with high grade new button cells.

So glad that I do not need/use the USB ports, or even need to have my phone 'Synced' to the car's system at all.

It's bad enough that the head unit does not eject the 'dinosaur era' CDs I use for a music source every third eject button hit or so, even after a hard reset (a battery disconnect is the only thing which will then allow me to eject said discs).

Battery was replaced less than a year ago. Should still be under warranty. I'll head over to have it tested on Monday.
