How do you open door of MK VI Golf if the car's battery is dead

Consult the manual I did. And guess what, it does NOT give instructions on how to replace the battery. So much for the manual. Also the key I have is a little different from the one show in the manual. The red light indicator on the key is on corner opposite the key release and not in the center as the one depcited in the manual.

I see some important information got lost in the crash. If your handbook is dated xx.2009 like mine is, it doesn't show the current key that we have in Australia.

To replace the battery:
1) Press the button that flips out the key
2) Turn the key over so the VW logo is facing upwards
3) Prise open the bottom half of the casing by pushing with your thumb in the aperture where the key sits when it's retracted. Be careful not to use excessive force.

This will reveal the battery, it's a CR2032 3V lithium.

Thanks to Corey R who originally provided the instructions.
