Correct. There's more to the story that's still being investigated.
You are supposed to be able to unlock it manually BUT some other failure prevented that. Side note, there is NO way to open rear doors from the inside manually on model 3.
You'll find this article below a bit better. Highlight: "When an airbag inflates, Model S unlocks all doors, the trunk, and extends all door handles." - which didn't happen here.

Fine, then retract your FALSE post in #1 that generated the inappropriate anger at Tesla in this thread.
