car wont start.starting sound is there after key is turned

Last month my car wont start. I went to local car mechanic and solved my problem for a cost $150.

This month the problem is repeated. Car wont start. While I push key and turn , starting sound is generated but car does not start.

I noticed the previous night of this problem, car is shut automatically but I did not press 'shut' button of my remote car.

Headlight and backlight is in trouble. It does not get switched on.
