need to get in trunk to replace the battery but key want work, battery down

is there a place to jump start the car under the hood even though the battery is in the trunk.? also, sounds like a booger, but sometimes you can access the trunk by removing the back seat back.

there is a positive terminal for jumper leads - face the engine - at the front of the block trhere are 2 black covers -the one to the left is oil check dipstick - the one to the right is has the + terminal under the cover - put negative lead anywhere on engine or body work earthing bolts where other cables are attached
