This is a bad problem with the Arnage, there is no easy way to access the cables or the locks with the hood closed. As Grease Donkey suggests, have someone inside the car pull on the release lever while you try moving the hood L/R and diagonally. The lock tongues are very sensitive and even with both cables good and tongues well lubricated the pins will not release if they are slightly misaligned. Once you get it open, if the cables and locks are working normally, adjust the pins so that they enter the locks exactly at the center point. You are lucky the driver's side id free, this is where the emergency latch is located. Worst case, pull on the hood, release the latch and get your hand on the center cable lying on top of the fan shroud. If the cable has snapped at the driver's end, pull off the sheath and then pull on the cable to release. If it snapped at the passenger side you have a big problem.
