The SKC is still valid. The defeat doesn't do anything to bits 32 and 33.

UNLESS you use an immo-off file from here, not immo-off your own file, in which case your SKC will be based on the 95040 bin you used.

Which immo-off file did you use? Post it here and I'll post a screen shot on how to determine your SKC.

That's an example, not your file, but the SKC is located in the same place.

So you want to know what your SKC USED to be?

You need to get it from the instrument cluster. Writing the immo-off bin overwrites the old skc with the new one.

For my own clarity:

It sounds as though the 'immo defeat' file changes or removes the security matching portion of the eeprom contents such that the SKC of the ECU doesn't need to match the SKC of the cluster; otherwise the immobilizer system is still functional.

Is this correct?

...The ecu can then be used in any car, however to do so renders the immobilizer is non-functional.

got it, thanks for the explanation.

So how do we completely remove the immobilizer? Can someone post an image like in the previous post? I believe I need to change 2 bytes to 4 somewhere 0x12 and 0x22 (read that might be virgin), is there a checksum we need to worry about?
