Pcm swap issues

I ordered a unlocked pcm to go with the new Trinity tuner for my 2017 Dodge Charger RT 5.7. After i got the new pcm swapped in the car will not start. The display shows the push brake and push to start but nothing happens when I push it. Im thinking the pcm isnt correct or something. I swapped back to the original pcm and it works as it should. Am I the only one to have this issue?

Certainly not common....
Can you try again and verify the connectors are properly seated, etc?
If it still wont start give us a call so we can attempt to verify the VIN, etc.
Thanks

I got it figured out. I ended up having to unhook both terminals of the battery for 5 min and then hook up the new pcm. It fired right up after i got it installed.
