2000 Liberty FOB doesn't work

[MILK]

Hi guys. I'm after a little advice on my 2000 Liberty. Since I bought it a few years back the FOB has never worked. Now some jerk has tried to break in and ruined my drivers side lock and I have to open from the passenger side... so I'd like to try and get the FOB working again!

I had a read of the advice on this link: http://www.cars101.com/subaru/keyless.html and had a play, but you need an already working FOB for it to work.

I also think from my research that the U.S may have had different system to that of Australia.

Anyways, any advice would be greatly appreciated!
