does anyone know how to remove rear seats out of a 2019 buick lesabre. what happened is i was replacing defective battery located in trunk. after removing battery, closed trunk and now i realize i can't open trunk because we took the battery out. no manual way of opening it. has anyone had to deal with this?

any assistance would be greatly appreciated

 

It would be much easier to just get another battery or jumper cables from another vehicle and connect to to the cables in the vehicle and just open the trunk.

The replacement battery isn't locked in the trunk, is it?
