The Keys (Seinfeld)
"The Keys" is the 40th episode of the sitcom "Seinfeld". It is the 23rd, and final, episode of the third season and the first of a three-episode story arc. It first aired on May 6, 1992.

In a montage of incidents, Jerry returns home to find that Kramer has overstayed his welcome; he had  been using the spare set of keys Jerry left with him. Exasperated, Jerry demands his spare keys back. The loss of the keys makes Kramer first rueful and then philosophically resigned. Disturbed by the change in him, Jerry tries to give the keys back, but Kramer refuses. Kramer then leaves for California to follow his dream of becoming an actor, after he is unable to persuade George to join him. Jerry gives his spare keys to Elaine. Soon after, he needs them and goes to Elaine's apartment with George (who has the spare keys to her place), to search  for his spare set. While there, they find Elaine's writing project for an episode of "Murphy Brown". As they read and laugh over it, Elaine walks in. Despite their positive assessment of her script, she screams at them to leave because they have invaded her privacy. During his travel to California, Kramer gets in a series of misadventures: his car breaks down, he hitchhikes three times (first with a motorcyclist, then a Volkswagen filled with hippies, and finally a truck driver), and at last resorts to rollerskating on Venice Beach in Los Angeles. Jerry is unable to locate Kramer  to make amends. One night, while watching "Murphy Brown" with Elaine, Jerry sees Kramer in a bit part on "Murphy Brown" as Murphy's new secretary, "Steven Snell".
