The address of the locksmith changes several times throughout the film and refers to locations in Portland, Maine - not Oregon: Jill's initial Google search shows it to be 789 NW Riverton, Portland, OR; the officer reporting it to Detective Hood states that Jill pulled a gun at a "locksmith over in Oakdale"; the police report regarding the incident lists the address as 651 Rivertone. Riveton is a street and Oakdale is a neighborhood in Portland, ME. Neither of them exist in Portland, OR.
When Jill is nervous getting into her sisters car in her driveway, as she looks around a black cat can be seen crossing the road behind her. The camera angle changes slightly and while Jill continues moving to enter the vehicle the cat is frozen in motion since the background is now a still photo.
