'Is it open this early in the morning?' 'They know me — I have an all-access pass.'
Literal
''Such morning-early [locative-から] open-[state-している] [explanatory-んですか]?'' ''I [topic-は] face-pass is [feminine-よ]''
顔パス (かおパス) literally 'face pass' is an idiom for being recognized and let in without needing a formal ticket, ID, or payment — the person's face is enough. Common in contexts of celebrities, regulars, or insiders. 開館 ('opening a building, building is open') refers specifically to museums, libraries, or other public facilities. The ~から here means 'from this (early) time'.
