It isn't explained why Father has to go back to Spivey's home to get his badge. "Spivey" was wearing a badge when he broke the patients out of St. Theresa's in episode 1. If Father needs the second badge to get inside the asylum, and access on the first badge was shut off... Father would have no way to know if access was turned off on the second badge. Or the first one, or why they would be handled differently.
