You have bad IMMO chip in key.
Do you have another key? Try with it.
If no, you need TWICE with paired key and TECH2 to marriage it to your car.
HiI think we need clarification on what you mean by "immobilizer."
The factory immobilizer is an electronic device that requires a specific, programmed key before the system will allow the starter to engage.
The shifter interlock - the thing that keeps the shifter in park - is not related to the immobilizer... that's an electro-mechanical system tied to the brake pedal switch.
What is your actual problem?
Hi Bob see my post below/above the WD40 has got the key turning.Forgot to add just for clarity so you know for future reference/terminology with Saabs: The "Immobilizer" actually stops the car from strart/running through the ECU & TWICE (Theft Warning Integrated Control Electronics, if I recall correctly). It doesn't do anything physical, but no one will be driving the car with it engaged.
The ignition key lock will prevent you from shifting out of park (or reverse with a manual), but it doesn't do anything specific to stop the engine from running... aside from the fact you can't start the car until you turn it.
Thanks Bob as its night time here i will wait until the morning then try. My next problem will be getting it through an MOT test we have to abide by here in the UK.Woo Hoo. You don't have to wait. Done it many times. WD-40 is non-conductive and was actually designed originally for electrical water displacement (WD). Fire it up. It is definitely advisable to remove the key cylinder at some point and clean it properly. But then again, before I knew that, I did the WD40 trick on several cars and they were fine for 50K miles.
FWIW, most of the WD-40 went through and is now under the shifter and oiling the top of what would be the transmission tunnel on a RWD car. If you end up in there for some other reason one day you can wipe up the excess, but it's not going to bother anything.
