Question type: Maintenance & Repair

NEED HELP!!!
Hello All,
I was working on my 2017 Lacrosse with the negative  battery terminal
unplugged. (Battery is in the trunk). My friend accidentally closed the trunk
with still the battery terminal unplugged . Now, I cannot open the trunk
backup again since it is electronically controlled.
Rear seat fold down lever is also located in the trunk.
Any ideas on how to open the trunk backup? Thanks in advance.

There should be a terminal under the hood connected to the fuse box. It will most likely have a cover with the + symbol on it. Connect a booster box or jumper cables to the positive. The negative can be hooked up on the strut tower or any other suitable ground. You'll be able to use the fob after its powered to access the trunk.
