Will turn over, new battery and still won’t start

If you put in a new battery did you disarm the security system before attempting a restart? When the vehicle looses main power the security system goes full active. I am also assuming that you didn’t use a memory saver tool at the time so may have damaged the BCM, when you do get it started if some of the accessories don’t work or don’t work right then that is what happened, so then you will need a shop that has access to flash programs for you vehicle or the expensive dealership.
