it took me a good week to figure out how to exactly work my trunk.
the trunk locks on the later model years (i think 98+) unlock with the power door locks.
to unlock the hatch unlock your doors and then move the hatch lever(in the middle of the hatch under the overhang) the left position from the right position help it up and release (or if it doenst go...push) the lever back to the right and shut to shut.
if this procedure isnt followed exactly the system doesnt know what state it's in. this can cause the hatch to pop up about a cm and then get stopped.
to remedy this open everything up the hatch, put the lever to the right and unlock the doors, push the latch to the left and let it snap back tot he right... it should close with no problem. follow the first procedure to open it and close it and you shouldnt have a problem.
i seriously thought my hatch was busted at first, but it turns out it's just a crappy peice of engineering.
