Locked keys in trunk

Help plase is their a release behind the back seat to open the trunk? What do I do? I locked my keys in the trunk

You can push back and then lift up the rear seat bottom cushion to remove it. Pushing back unhooks the front of the cushion from the mounting brackets. You will then be able to see the two bolts on the bottom of the upper seat cushion that hold it in place. Remove these two bolts and then lift up on the cushion to remove it. You can then reach into the trunk and get your keys!
