If not, locate the release catches for your hood. Look on the sides or under of your engine compartment and see for release cable attached to latch. Use a coat hanger or similar tool to catch the release cable and trigger the cable. There is normally a 1/2 inch loop at the end of the release cable that either needs to be pushed or pulled to release the hood.
