Privacy Lock Twin-Blade Emergency Key
This is a 96 mm flat emergency key that opens the outside release slot on a bathroom privacy knob or lever when a toddler locks themself in. Both blades are 1.6 mm thick. One end is a stepped narrow blade, 3 mm wide at the tip and 5 mm wide behind it. The other end is a coin-style blade, 9 mm wide at the tip and 12 mm wide behind it. Between them, these cover the common release-slot sizes without guessing a single brand's dimensions. A 6 mm hole in the 50 x 22 mm grip lets it hang on a nail on top of the door casing, where it is always within reach.
Flagged: a sharp edge or blade. Not for safety-critical use without independent engineering review.
