The door to the gas tank on my 2001 Civic won't open. I press down on the release button in the car and nothing happens. Does anyone know how I would go about fixing that? Do I need to take it to a mechanic, or could I do it myself? What might it cost me if I took it to a mechanic?

Thanks.

 

Try putting a screw driver in it to pry it open... this happened to me. U might want to put a rag under the screw driver so u wont chip the paint tho.
