What is your question?

I have a 2004 Mercedes Benz S430, the battery was dead, I jump started, I went out but the next day I tried to started but it won't start, trying to jump start it nothing happen. I took the battery to the store that I'd bought it from, they charge it, come home, it would not start. It unlock the doors but the folded mirrors will not open when I open the doors, put the key in the ignition it would not turn or start the car. I change the remote battery, I still have the same problem. the car would not crank. Please help!!
