Movie about a grocery bagger killing people in his town

Saw this movie on Hulu I think. US film–maybe late 2000’s, early 2010’s. A guy working as a grocery bagger gains access to people’s houses by taking impressions of their house keys, while he helps take their stuff out to their cars. Unfortunately I do not remember much else. I believe he killed one of his victims over and over, bringing her back to life with no memory of what happened. I think she gets suspicious and sets up security cameras and learns what he is doing. Eventually she is able to stop him. It was a decent watch, and I’d like to see it again to see if it holds up. Unfortunately, nothing comes up when googling the plot. Hoping someone can point me in the right direction. Many Thanks!
