Help please :(
 

To make a long story short, I walked out to my car this morning to find someone had smashed my passenger window with a giant rock. So, that was fun. After finally getting an appointment to fix my window, I got in my car to drive to Safelite and my car won't start. A man came out and tried to help me, but we could not figure out what's happening. He tested my battery, everything is fine there. Nothing seems to be wrong with the engine and, to my knowledge, nothing was wrong with the car before this. Started fine.

The security light is blinking red, so wondering if there are censors in the window that have made the key lose interaction with the car and that's why it won't fully turn over? I have no clue about cars, but I am very frustrated and have cried a lot today so any help or ideas would be amazing. Thanks!

Year of car?

Does the car have a factory or aftermarket alarm?

Do you have more then one key to the car, if so try the other one.
