Everyone thank you for the help. Both locomotives are now reprogrammed. They both run well too(second hand). I would like to  eventually upgrade, but money is going towards changing a room around for twins and preparing for them to  arrive. So until everything with that preparation is complete I will just continue using this  controller. Again really I thank everyone and it's also to have friendly people like this in any hobby. Stay healthy with this craziness out there currently.

I don't have a manual(second hand), I tried googling, I tried watching videos, and nothing has showed or helped.

So I have the Bachmann ez command control and I have 3 locomotives that all work with it with no problem And none are Bachmann(sorry it's you don't have any Lehigh valley gp38's or gp7 their scenes). I just got two used locos that aren't Bachmann and are dcc ,but they are used and I don't know their home address(not 1-9 on the controller). Does anyone know how to reset them to default 3?
