My car's battery died and the key is stuck in the ignition. How do i remove the rear seat to gain access to the battery.

 

Moved from how-to. You don't have to remove the rear seats. First, where is your second key? Second, a dead battery is not the reason your key is stuck. Be sure you are in park, steering wheel not tight (causing the tumbler lock), and just take it out.

 

Open up the hood and jump the battery(Boost with another car) using the post on the fuse box and grounding on the top of the strut tower .
That should give you the power to get in the car with litttle hassle,and pop the trunk as well.
