Au keyfob help needed

Hi all
I just brought new keyfob a for my au wagon as I did not come with any. I have followed the process to a tee acc on rear dim mister 3 time with in 5 seconds to activate the Learn mode of the system and nothing it won't let me in so I can reprogram the new fob, I even checked the rear demister to ensure that it worked as I thought there may have been a broken cycle and no problem there,
I have now done a lot of reading on these darn system and just can't find what I need can any one please help
Cheers doug
