Ok,

So I am dumb for doing this at work, but I just replaced my outer beat up key fob case with a better case from my other crossfire. Doors work fine, Goes into key hole fine. Issue is when I start the car, it starts up for a seconds or two and then dies. Did this about 2 time and now it wont start at all. Thought it might have been the rcm like I had issues with on my older crossfire but I fiddled with it and unplugged and re plugged it with the same issue. Does anyone know what might be causing this or is it a coincidence that this happened right when I replaced my fob case? Literally bought the car used two nights ago and this is happening just now. Any help would be appreciated.
