DE Extraction Key

A small, unadorned metal key no longer than a thumb, its flat head etched with minute grooves instead of ridges. When presented before a biometric lock, it triggers a silent servo-driven drawer of light without audible clicks, confirming its legitimacy. Its monofilament-thin clearances bypass standard security measures with precision.
