After a simple brake pad change, drove my car around the block, everything was fine. Went inside and came back out to leave and my car wouldnt start. I tested my starter, power to the starter, battery, ect. I'm left with either a voltage receptor, or a bad ignition switch. Any thoughts?

 

You may have a vats problem is the security light on

 

I feel like an idiot asking this, what light exactly? Only lights on the dash are service engine and the seatbelt one. once the car is started they both go off though so thats normal.
