How do i diss-arm the engine immobilizer? - 9000 Saab Cars & Trucks

The 'immobilizer' is an integral part of the engine computer and cannot be disarmed. It can, however, be tricked. There is a device used on cars with this system that tricks the computer to think the key is there during remote start. The bypass module, as it is called, learns the transponder code from the key (more advanced models) or just uses a spare key with a transponder in it to trick the engine computer. This requires you to have the key to the vehicle. If you don't have the key, the only option is to get a dealer to cut you one based on your VIN number. You'll have to provide proof of ownership. They do it this way because just anyone could get a VIN number from a parking lot and have a key made if they didn't require proof of ownership.

Now, you didn't give any information about what model car you have and the year, so I can't give you more detailed information on what type of immobilizer system the car has and different ways, if any, that it can be tricked. Keep this in mind when you rate.
