Ain't life a bitch, but you gotta keep her wet
Keys open doors so I gotta keep a set
Ross refers to Nas’s “Life’s A Bitch”
“Ki’s (keys) open doors” is a play on words, a reference to kilos of cocaine and the Clipse song of the same name.
Here, Ross is expressing the financial opportunities (opened doors) that moving cocaine can afford him.
As Big Sean said
Ki’s open doors, but bricks open windows.
