On "Seinfeld", what was the name of Kramer's movie treatment?

On Seinfeld, Kramer's movie treatment was called “The Keys.” The title refers to the spare keys Jerry takes back after Kramer repeatedly treats Jerry's apartment as if it were his own home.

The story unfolds in “The Keys,” the final episode of Seinfeld's third season, which aired on May 6, 1992. Jerry is fed up with Kramer borrowing possessions, using the apartment freely and turning up at inconvenient times, so he confiscates Kramer's keys. Kramer sees the move as a betrayal of the informal “covenant of the keys,” and the dispute sends him on an impulsive journey to California to pursue acting.

The treatment is part of the episode's larger satire about Hollywood ambition and personal grievance. Kramer's trip includes hitchhiking, a biker, a hippie van and roller-skating at Venice Beach before he lands a role on Murphy Brown. The episode ends on a cliffhanger that continues in the fourth-season opener, “The Trip.” Viewers sometimes remember the title as belonging to the later California storyline, but “The Keys” is both the episode title and the name associated with Kramer's movie treatment.
