supposedly you can remove the interior trim and open the latch with a screwdriver manually from inside the vehicle but I dont have any more details than that.
I just completed the same repair and can confirm the computer part is not needed. Looks like the trunk closed and used the computer to send the unlock command like pressing the button. Hope that helps.
@@TmJE5 so during installation one must make sure not to drop the hatch to where it latches locked? I mean in a tutorial video, it would be wise to mention :)
