Ignition and Door Keys

Correct me if I’m wrong, but weren’t the ignition and door lock keys different - pentagram head on the ignition and round head on the door keys? In the case of my 65 sedan delivery conversion, i have 3 different keys - an ignition key, door lock keys (NOS locks with the keys) and a NOS glove bock lock key. I still need a key for the tailgate power window. Would you get the ignition key to operate everything (like a modern car), or key the tailgate lock to the ignition key (which is what I suspect the factory did) or key the glovebox lock to door keys and have 2 keys like they had originally.
I think there were some changes thought the years. My 66 and 70 both use the ignition key for the door locks. The trunk is the separate round key.
