Normally when you push down on the hood and pull the release simultaneously it should open. If it does not I suggest you go to the nearest Auto Body repair shop and let them open it for you. This is a enclosed cable that runs from inside the vehicle to the middle of the hood. There is no other cables or devices in between. The shop may do it for nothing or just a small fee. It would be a lot easier to do that than to do damage which will cost a lot more.
