For 2019+ in order to program the inmobilizer and allow the vehicles to start and run if you replace the PCM, is not as easy as only changing the VIN number.
Not done much of this latest models, but from 2018 on things changed in security systems.
Correct, before 2018 its doable and pretty easy, its the new security features in the 2018+ models with the secondary gateway behind the radio that makes it hard to do these new PCMs.
I just programmed a used ECM on a 2020 RAM Cummins last week. The whole job needs to be done with CDA6 on the bench.
1) Rewrite VIN
2) Run ECU unlock function (all 3) this puts the ECM in programming mode and wipes immo data
3) Flash with correct calibration.
Install and start vehicle. Easy peazy
