I have heard of people using a small charger and going thru the cigarette lighter jack, ignition must be on.
You can cget under the car and find the lead to the starter.
There is a connection under the front floor mat in the foot well (tough to get at)
Why would the manual lock unlock the lid? I assume you have turned it 90 degrees and Then pushed the button.
I would opt for the first, you just need some power to get the locking pump to work.
