These sounds were made by this upxon-brand, key-size combination lock box: https://www. Amazon. Com/gp/product/b08ldj479d/. I bought this, and while fiddling with it i became mesmerized by the sounds it made. So i decided to record them foley-style. Recording starts with 15-second noise floor. Recorded with an iphone 7.
