Does replacing the rf hub mean your old keys no longer 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.
