Complete story — includes the ending
After finding Kramer in his apartment at all hours in unwelcome situations, Jerry confiscates his spare keys from Kramer.

Kramer leaves for California to break into show business, vowing to free himself from Jerry's hospitality, but Newman divulges that Kramer really left out of resentment. Jerry, George, and Elaine all reshuffle custody of their spare keys, but Jerry ends up locked out of his apartment with Elaine and his spare keys nowhere to be found. Kramer has many hitchhiking misadventures on his journey to Los Angeles.
