google how to program fob for 2011 chevy malibu for more info

On the Chevy key fob, press and hold the "Unlock" and "Lock" buttons at the same time until you hear the door lock and unlock again. This means you're all set. Re-insert the programmed key back into the ignition to the "On" position to finish the Chevy key fob programming process

Climb into the vehicle and close the door. Insert the key into the ignition but do not turn on the vehicle.
Hold down the "Unlock" button on the driver's door while turning the key to the right to the "Accessories" position. Continue holding down the "Unlock" button.
Turn the ignition key back to the "Off" position while continuing to hold the "Unlock" button then return the key to the "On" position again. Then return the ignition key to the "Off" position. As you complete this sequence, the doors will lock, and the horn will sound, indicating that you've entered the programming mode. At this point, release the "Unlock" button on the driver's door.
Push both the "Lock" and "Unlock" buttons on the key-less remote and hold them for roughly 15 seconds. Release the buttons when the locks click again.
Insert the key into the ignition and turn it to the "On" position. The horn will honk once more. This indicates the programming has been successful.
Remove the key from the ignition. Climb out of the vehicle and try locking and unlocking the doors with your remote key.
Tip

• The H3 uses a Tech ll code system that often cannot be re-programmed without the help of your local dealer. If you are unable to reset your key-less fob using the steps above, your local GM dealer will be able to help.

I imagine the obvious answer is to use a key in the door lock cylinder. The reason you have done this is because there is no door lock cylinder! You only have a fob is my guess, that electronically opens the doors. Dead battery..and the fob no longer works. Don't worry, examine your fob and there should be a way to open it. Carefully open the fob and surprise! There is a key inside of it! Now take that key and there ahould be a key lock cylinder above your rear license plate. You should be able to open your rear hatch. Now somewhere to the drivers side in the rear compartment there should be some sort of pull you can use which will open the drivers door. Hope that helps you out!

You have to go to a Chevy dealer. They have a hand-held computer they plug into your car to get it into programming mode. Probably cost $50-$60. Call them for an estimate.

disable door lock...Close all of the doors of the Caravan and insert the key into the ignition.

Move the key to the "ON" position, and then back to the "OFF" position. Repeat this step four times.

Press the driver's side door lock to the "LOCK" position within 10 seconds of turning the ignition to the "OFF" position. If done properly, a single chime will emit from the Caravan to indicate that you have disabled the auto-lock feature.
