You can do exactly the same thing by removing the inner glovebox screws. The keypad module is the small box attached to the left hand side of the stereo centre frame.

Disconnect the big white connector and press 0 and star and reconnect.

To disarm the brant module into manual mode (until you can get it to someone for repair,diagnosis or removal) , you can press the number "2" on the keypad while the 7,4,1 sequence is flashing up to force the unit into manual mode.

If you're in a MY05 -> MY01 car.. i would suggest carrying a screwdriver (if its not already included with your tools bag) for one of those moments when you are stuck in the middle of nowhere and by yourself.

You can also replace the modules internal battery yourself with a few parts from "Jaycar". I might put up a howto with some images and diagrams later..
