Does replacing the rf hub mean your old keys no longer work?

So went to a pick and pull earlier today and they had 4 dodge darts , picked the rb5 tuner,side mirrors with puddle lamps , turn signals and heated as well as the rf hub , keyless entry and remote start antenna and the heated seat module. I have alfaobd and I am wondering if I swapping out the rf hub will erase my keys that are currently programmed to the car ? I also seen that under car configurations that you can activate the turn signals and puddle lamps , does activating them in alfaobd work ? Last question is what settings need to be active for remote start to work ?

The FSM says a dealer needs a 24 hour PIN to get a new RFHM to recognize your key. People on the Ram Forum are doing it with their PIN that alfaOBD is able to get. Let us know if it works.
Be sure to make a backup of your BCM configuration before you make any changes.

Do a PROXI after each change. Search the Ram site for the alfaOBD changes you want to do especially the backup.
Not sure if a used RFHM will overwrite the PIN. You might have to solder in your original chip.
