Car not starting

Need more info /// does the car crank or do you just get that noise?

Are there any messages on the console ...ie;"security" or "Check Engine"?

i'm leaning toward security or starter solenoid... depending on if security light stays on after test loop of 10-20sec. start up key turn.

The security light comes on sometimes When i was able to drive my car

Is it on now? If it is you may need to call a locksmith ( or the dealer) who will reset your security system
