How to open the trunk on Buick lacrosse with no button on the door?

To open the trunk on a Buick Lacrosse without a button on the door, you can use the key fob by pressing the trunk release button. If you don't have the fob, you can also access the trunk using the key itself, inserting it into the trunk lock. Alternatively, if the rear seats fold down, you can reach into the trunk from the cabin.
