There's places on line that do replacement fobs, but first you need to identify what make and model your immobiliser is. Pics. would help.
The coding on fobs of E30 age is usually done by bridging or cutting tracks on the fobs circuit board.
The best solution is usually to remove the old unit, and replace it with a modern remote locking unit from the likes of Rightclick, which will come with two nice new fobs.

where abouts would the immobilizer unit normally be mounted?

If it's not under the bonnet, the correct place is above/behind the glovebox area, where BMW provide most of the connections for it, but if it's aftermarket there's no guarantees. There's a panel that comes out with a couple of quarter turn things and a cross head screw.
The genuine BMW version has a box behind the glovebox and a horn under the bonnet.

i doubt its a official bmw one since all it seems to do is stop the car getting reds entirely , did aussie e30s even come out with factory immobs?, ive gotta get a key code from the dealer and get a new key cut tomorrow so ill check out those places for the unit cheers

An alarm/immobiliser was an optional extra on E30s. Quite an expensive one - it cost about the same as a LSD, but unfortunately was a far more popular choice.
There were also a couple of BMW 'approved' alarms that were fitted by dealers.

Found the little bugger behind the dash cluster bit tricky to get to without the steering wheel, its a aftermarket autowatch 674ri immobiliser and i have no idea how to remove the thing , ive called a automotive locksmith and they said they never heard of em so im a bit confused i dont think ill be able to get a new buzzer made

Have you tried contacting the manufacturer? Autowatch seem like a pretty big company in New Zealand.
