Spare PCM Purchase for 2017 Ram 1500 Rebel

[earendall]

I have a 2017 Ram 1500 Rebel and I need to get the PCM unlocked but I don't want to pull the one in the truck and be down a vehicle.
I'm looking at getting one from a salvage yard or eBay, is there anything that I need to be aware of? Mid year PCM change, etc?

TIA

Just match the part number to yours and get the vin added to the new PCM,
I can help with that if you want to send it to me.
