Will not crank over?

I have a 2007 Camry. I came out and found the battery had died. Looked like I had left the lights on but I'm not sure. In any case, I replaced the battery and still won't start. The car has a push button starter; the light goes from amber to green when I press the brake pedal but still won't start. The dealer said to replace the remote battery-still doesn't work. The remote does nothing-doors won't lock or unlock. Lights do turn on and the GPS system screen lights. Battery light and engine service lights on. Car is otherwise dead!
