Looking for some help for my 2017 Ram Sport Night edition, V8 5.7L HEMI.

I have two key fobs and one was in my wife's vehicle so I tried to use my spare to start my truck . Turns out the key had a dead battery (didn't know that I could start my truck with a dead key fob until reading on here yesterday) so later that day I replace both key batteries and hit the unlock lock buttons and they work. Next day I go to start it and my dash is saying "service electronic braking system" and "park sense off" now it wont start and the brake peddle is hard. I only stepped on the brake peddle a few times trying to get it to start. All the lights and radio work fine. I tried disconnecting the battery to try to reset the computer but it didn't work.

Any help would be appreciated

That's interesting. I need to put a battery in mine soon, hoping I don't have similar issues

i seriously doubt that the changing of the battery had anything to do with the problems.

Just for grins, press the Panic button on either of the FOBs.
If the ALARM goes off, the FOB is still connected to the Rams RF Hub

I also doubt that your FOBs Battery was even close to dead
Of course, we will not know unless you tested it

Update. Changed the battery and it fired right up and the service electronic braking system message went away and park sense is back to normal.
