    Hello guys, we got our firts Dodge ram 2019 CM2450b, we found stock tune in database 54.19.01.03 - IA80009.04 54360961AB 2019 DJ D2 6.7L PCM EURO V,

    we modified and tried to flash but got this fault during programing: error $0537: Controller is locked with a custom key.

    Hard to give a definitive answer immediately.
    Many changes have been made since support was added for that ECM back in Sept 2019, maybe consider updating to our latest beta here and retrying the flash:

    Failing that the only way we could possibly assist is if you can get trace files of this failing flash. See HERE on how to do that, you can post them up here if you want as the support@efilive.com Email is not generally monitored all weekend.
