In my opinion, the solution is better explained with pictures of the release apparatus from underneath the car, found in front of the radiator. Try to take a picture and post here for further direction.
Or, with any luck, someone here on the forum may already have pictures and can better explain the process easier.
But one solution is this.... There is a piece known as the "Striker Pin" mounted to the underside of the bonnet. Think of that as the male connector held in place by means of a female opening as part of the chassis framing (adjacent to the cowl) and offset slightly to keep it in a closed position and spring loaded. A picture of the part can be found on one of any popular parts catalog. Using a long screwdriver with a wide enough edge end, I was able to pry away the tip of the striker pin from the adjoining side which would release. It is really easy once you figure which side is the correct side to pry away. Hope this helps you. Good luck.
