Aside from a well-trained wizard or warlock, you canuse the spell Knockto unlock the passageway. you may also brute force it with someone like Karlach,who can just smash the stone wall downand walk in.
Alternatively, there isa hole in the wall down the south-side stairsof the mansion, hiding behind a wooden crate. If youshapeshift into something small, you can also enter this way.
