Just to be safe I'm going to go tonight and purchase new batteries for the two key fobs. Then I will respond back.
The two SRT6 key fobs work perfectly fine.
The Limited doesn't work at all.
All three key fobs I opened up the same way and transferred them to a new case because they were pretty beat up.I really hope I didn't break the electronics board on the Limited somehow. But just visually inspecting it, it looks great.
JFYI, I am following this thread cause after replacing my case, it no longer works either. I can see red flashes but not working. car starts fine but can't use lock/Unlock feature? Hopefully a solution to this problem.
