Does the 06 Monte Carlo SS have Passkey III or Passkey III+ ??? Can I tell by looking at the key? There is a + on the key I have. What is the difference between the two systems?

I had to replace the exciter ring with a used one from another 06 Monte and the engine will not crank and I get a "service theft deterrent system" on the dic.

I have tried to reprogram with the 30 minute cycle for the Passkey III but nothing is happening? Also, how can I find out what option codes my engine has? By the vin?

This is an engine swap so I don't have the car, just all wire harnesses and computers.

Thanks for any insight into this.

Im not 110% sure, but I believe the book tells you its a Passkey III+ or IV. It will also tell you how to reprogram your key and remote.

If you need anyhelp, please let me know.

Yes! Could you help me out and tell me how the book says to reprogram, Your key has a + with a circle around it?

Thanks

Start at page 108 and go from there.

Your welcome.

Thanks for that link, it helps explain some things.

However, I don't need to reprogram a key or remote. I think since I changed to another exciter module in the steering column I need the theft system to work with the "new" part. I need the bcm to "accecpt" the new exciter.

The bcm, ecm, and key all came from the same car, only the exciter was from another Monte that I think has a different code in it that is preventing the engine to crank.

Thoughts?

Key needs to be re programmed through a dealer along with the BCM.

I know the video looks like a mess, but I had to hear it run before I put it away for a wile.

The "shop manual" says that to date there IS NO way to reprogram the Pass Key + so I was forced to use the smashed VTM.

Thanks for the help.
