Lock Charmer received positive reviews upon its premiere at the 2014 Sundance Film Festival. Geoff Berkshire of Variety, said in his review that "Natalia Smirnoff's second feature is a wisp of melancholy comedy with a dose of magical realism."^[8] Boyd van Hoeij in his review for The Hollywood Reporter called the film "A modest but quite charming feature about an Argentinean locksmith who unlocks truths about the lives of his clients."^[9] Eric Kohn from Indiewire praised the film by saying that "Measured and never indulgent in its depiction of the plot's mystical ingredients, “Lock Charmer” does a great job at blending two genres and placing them in the strangeness of the 2008 setting" and praised the performances of Lamothe and Huaripata that "Lamothe portrays the locksmith as a man at once perturbed by the behavior of the women in his life and resentful towards his male role model — namely, his estranged father. The natural chemistry between him and Huaripata, as Daisy, matches the efficiency of the movie's direction."^[10]
