a golden key can open any door这个短语的含义不是指“金钥匙可打开任何门”，其正确的含义是有足够的钱可以做成任何事情；没有钱办不到的事。

【例句】
Although the fancy hotel had been booked solid for months, Lori was able to reserve a room quite easily. A golden key can open any door.
虽然这间高级酒店几个月来一直被订满，但萝莉还是很轻松地订到了一间房。有足够的钱可以做成任何事情。

She comes from a wealthy family, and a golden key can open any door.
她来自一个富裕的家庭，有足够的钱可以做成任何事情。
