There is one part of the answer I forgot to mention. When you program keys, it also transfers this "Secret Key Information" to the Chip in the key. This information "MARRIES" this key to the vehicle. When you replace the PCM and the SKIM at the same time, you lose this original secret key information. The key "PERMANENTLY" stores this info and it cannot be changed in the key. This is why you keep getting the message about using wrong key.
The way to avoid this from happening when both modules must be replaced at the same time is to replace the SKIM module first while using the original PCM, you run the "SKIM Replaced" first. This transfers the "Original" secret key info to the NEW SKIM module. After this operation is complete, you can at that time replace the PCM then run the "PCM Replaced" routine. This will transfer the "Original" secret key info over to the NEW PCM. If you would have been able to perform the procedures in these steps, you would have been able to use the "Original" keys and they would have successfully programmed to the SKIM. I'm not certain what may have happened to that "New" key that is not allowing it to be programmed....
