If you get under the dash you should be able to hook up a small charger to a main red wire and ground
That will charge you batteries good enough to open the hatch.

There are 2 ways to do it.
One the easiest look under your dash find a main hot wire(+) and a ground.
Hooke up your charger and turn the charger on.
You sould get enough power to open the hatch.
Second you should have an opening somewher oround the engine hatch in order to pull the pin out of the lifting rod.
