The immobilizer system is not something you can tamper with for a work-around. The only way you could bypass it at all, is with a K-Pro converted ECU.

It Wasn't Me

In the event that should have to change your ECU again; get one from a parts car along with the key(s) and ignition switch cylinder from the same car. Might as well get the door lock cylinders from the same car while you're at it. That way the ECU/immobilizer, key(s), and all cylinders match. Assuming this is an option, of course.



Hmm.. that being said, I bet a number of people would rather just pay for the reflash. Less work. lol
