Key Lock Box Basics: Spare Key Storage Without a Physical Key

The direct answer is that a key lock box replaces the physical hand-over of a spare key with a combination code. According to the series description, it uses a combination or key access method for securely storing spare keys and is widely used in homestays, real estate agencies, renovation sites and home emergency use. The lock box is made of high-strength metal material with excellent resistance against impact and prying, and it can be mounted on walls or door handles. Zhejiang Rongtao Hardware Products Co., Ltd. owns the Yiwu Shengping Lock Factory, which has nearly 30 years of professional padlock manufacturing experience, and the Key Lock Box range sits in the same catalog as its combination, brass, aluminum, rectangular, iron and stainless steel padlocks.
