When I turn the key to start my 2007 Honda Civic, nothing happens. The dashboard lights will go on and the radio plays, the headlights go on. I just had a new battery put in and a new alternator. There basically is no sound except a little click when I turn the key. Any ideas?

What prompted the battery and alternator change? Will the car start with a jump? If it is a stick, will it start with a push?
