2006 Saab 9-7x PassKey III (PK3) issue

[Diesel_Geek]

I'm swapping in an LS6 for the hurt LS2 (aluminum 5.3). All is going well except for the vehicle security system. The vehicle security light wont go out and I can't seem to disable it. I've disabled VATS as well as setting P1629, 30, 31 to No error reported.

I drove it into the shop. Every plug and ground is reconnected. I have tried to make it relearn the only key but I've had no luck.

I can't start it from the key at all. Starting from the the starter solenoid gives ~5sec of runtime.

Any advice or assistance is appreciated.

Thanks,
Mark

VATS/PassKey is nothing to do with the physical engine, if the ECM and ignition cylinder and BCM were not changed you should not have to do anything - not a security relearn, not a VATS disable in the tune. I would guess that you have some other install-related error.

EDIT: Sorry! The Saab uses a transponder key and a dedicated VTD module instead of lock cylinder & BCM... but other than the names of the components, nothing changes from what I said above. If those parts did not get changed then this is not a security issue. There are no transponder chips/etc. in the engine block/heads/crank.

I know it uses a transponder key. The transponder is malfunctioning and the parts are made of unobtaium. I was hoping to program around it.

Did you do a write-entire after changing the VATS settings in the tune?

Yes
