Can you get at the wire cable? I've seen several hood release handles, where the plastic handle broke, but, the wire cable was still there. I used a pair of vice grips to grab the wire cable and pull.
If there is no wire cable to grab, maybe you can remove the front grille, see if you can reach the release mechanism to open the hood. I've seen universal hood release cables in the autostores, I thought they were over-priced.
