Does anyone know how to bypass the factory immobiliser that comes on these cars standard???
An autoelectrician told me that i have to take the car to a dealership and have the barrel change and reprogramed at about $800, others have said on the forums that it can be bypassed but not how.

Why do you need it bypassed?

Ah cheers.

I'll look in my manuals and see if I can find anything, I do have my doubts...but I'll look.

I have a TS 4 cyl exec and faced the same problem. If you pull the ignition key barrel out (I did it to lubricate it) the immobiliser kicks in and the car will not start. To check that this is the problem, put the key in the ignition and swich on but don't start, then wait for 30 minutes. Now try starting it - it should start. The fix? A new immobiliser from the dealer and a reprogram of the CPU. My fix? Cost me nothing - let me know if you are interested!

Oh, ok then... I will tell you now.
Pull the immobiliser off the car - involves dropping the lower shroud and the steering wheel (not really necessary, but gives you better access). Use a pin punch and hammer to undo the snap off bolts that hold the steering lock in place. Pull the whole lock with immobiliser and barrel out of the car - don't forget the wiring connectors. Put the key in the lock, turn it to acc and push the pin on the side - the barrel comes off easily.
Now the tricky part - use a small hacksaw to cut open the locking sections of the immobiliser. When you pull the barrel, a spring pushes a white plastic plate off the shaft. This normally rotates and cuts a light beam on/off as you start the car, but with the white plastic pushed off the shaft the ECU thinks some thief has ripped the ignition lock out and is trying to steal your car. Remove the spring and push the white plastic disc back in place. Glue it down if you want to, but I didn't bother. Put the immobiliser body back together, and wrap masking tape around it to hold it together. Reassemble in reverse - the break off bolts can be reused or use ordinary 12 mm head bolts like I did.
I did this "fix" 12 months ago and have had no problems - no immobiliser either, but who is going to steal a 11 year old Magna when there are Commodores around? LOL

i posted a new thread and I think I have similar problem as andrewflorence. Andrew, could you please tell me which auto elec who quoted you $800 for bypassing? Are you in vic? thanks. Jenny
