Default 2011 Sonata limited 2.0 Turbo not reading Key fob / issues

I have a 2011 sontata with a key fob. It has worked perfect until 3 days ago. All of a sudden the car wasn't reading the fob (already had the break switch replaced). I had to insert the fob into the dock in the center console and then the car would start. The issue is that the Trunk Open, and tire pressure lights are on, The sunroof, and door locks wont work (even with the fob inserted and car running), the blinker lights on the dash arent working, and only the passenger head lights work. After 1.5 days of this then it worked fine for about 24 hours, and now the problem is back. I already changed the battery in the Key fob, but I don't have my spare because I am in texas (I live in vegas) for training with the military for 6 more weeks, and then I have a 1100 mile drive home. Has anyone seen this before, or know what the issue could be. I have read forms and the car's manual, and I checked every fuse that I though might be involved with the system. Thank you for your help.

Go back to the dealer and have then reprogram the fobs again. Just be sure to take all fobs with you.

Today I popped the guys again and started looking at the wires that go to the terminals. When I moved one that goes to the negative battery terminal I heard a buzz so I missed that quite in a little more and everything works fine now. When I get back I will actually fix it.
