Best Small Key Lock Box in 2026

Solid steel, a keypad lock, and a removable shelf — this compact safe handles the essentials without fuss.

Two override keys are included for dead batteries or forgotten codes, so hide them somewhere smart. Pre-drilled holes and four expansion bolts let you anchor it to a wall, floor, or shelf, which is really the point of a box this size.
