1999 Chevy Silverado V8 Four Wheel Drive Automatic 248000 miles

I have a replacement ECM from NAPA that was flashed before shipping from A1 Cardone. According to the instructions I will have to perform a Passlock Relearn procedure. This entails cycling the key and waiting on the security light. Is there anything else I will need to do to complete this process.

Do you
have the same problem?
Yes
