Boxster hood lockout

[Hillman]

I keep my '02 Boxster up in the hills, far from any town or Porsche tech. The rocker panel switch stopped "releasing" the front trunk. I found the auxiliary release wire that runs along the inner front fender and used that a few times. Now the release wire refuses to budge. The car sits unused for months at a time. Now I can't get the front lid open to connect the battery. How else to pop open that front lid? Using the jumper cable attachment inside the fuse box, I could hear the switch activating but the latch doesn't respond. Is my only option having a flatbed take it to a technician? Help. Thank you.
