Recently i had the same problem when my 2006 BMW 320i's battery went dead and everythng seemed locked, even the key got stuck and i had to pull it out forcefully. To open the boot you have to charge the battery, now you must be thinking thay battery itself is located in the boot. Right ? Still you can charge the battery from the bonet(hood) of the car. you can open it coz it can be opened manually. now on the middle left side of the hood, you can see a metal plate with a red cover on it. Connect the positive wire of your other charged battery with it, and connect the negative terminal with any of the screws you can find near that postive wire on the hood. Now try to start the car and once it gets started, open the boot of your car and try to replace the battery because it may happen again.
Hope it may solve your problem.

The hood should still open when the battery is dead
manually: insert key, turn, lift boot. voila :)
It's in the boot, or trunk if your in the USA. If the battery is flat, then you need to open the boot with the ignition key - look between the X and the K on the rear badge.
With your key.

When the battery is dead in a 97 Catera, the electric locks will open manually with the key.
