The Penthouse Key is the distinguishable trademark of the Penthouse brand.

This unique key is composed of the powerful female symbol which represents the union of the divine and earth referring to women as the Earth Goddess. This is also a symbol for Venus, the planet of love and beauty.

Within the female symbol lies a small male symbol, which denotes the union of the divine and the stars refering to men's awareness and preparation for what lies in the future. This is also a symbol for Mars named after the Roman god of war.

The Penthouse key suggests that women hold the power or the "key" to men physically and sensually and together they can unlock the door and unleash their deepest fantasies to a place of infinite possibilities otherwise known as the Penthouse.
