Keys Open Doors is the third episode of the first of You're the Worst, which was first broadcast on July 31, 2014.
Gretchen hints that she might need a key to Jimmy's house. Jimmy misinterprets it as her wanting to take the next step in their relationship, but she insists that's not why she brought up the idea. Gretchen has to smooth over rapper Sam Dresden's latest PR blunder. Jimmy sees a text from Gretchen's other lover Ty while returning her phone to her.
He follows her to a bar expecting to see her on a date, but instead finds her at her birthday party, to which he was not invited. Becca and Vernon are there, forcing Gretchen to reveal her relationship with Jimmy, to Becca's horror. Returning to Jimmy's house, the two find Sam in an unexpected situation.
