Key
Cracker

Compendium Entry #7

small red legs key crab

Introduction

Every lost key, every mysteriously opened lock, every inexplicable security breach points to an the unsettling truth that mechanical security exists in constant silent war with a living lockpick. The Key Cracker’s evolutionary path traces perfectly alongside humanity’s attempts at creating physical security, from ancient Egyptian tombs to modern electronic locks.

Classification

Common Names: Key Cracker, Key Crab, The Locksmith

Family: Reversocrabanidae (Reverse-Carcinization Crabs)

Genus: Urbacrabus (City Crabs)

Species: Clavisfrangus (Key Cracker)

Variety: N/A

Description:

Key Crackers measure 2-4 inches in their natural state, though size varies based on the key form they replicate. Their base coloration shifts between metallic hues – brass, silver, aluminum, steel – allowing perfect camouflage among key collections. Most remarkably, their exoskeleton contains traces of every common key metal, enabling instant molecular reconfiguration to match any key composition.

Special Adaptations

Through some extraordinary mechanism, these creatures understand lock mechanics at a fundamental level. Their bodies can instantly analyze and replicate any key’s tooth pattern, warding cuts, and security features. More incredibly, they can modify their forms to match keys they’ve never encountered, somehow intuiting the exact shape needed.

 

Multiple intelligence agencies maintain “mechanical access” programs devoted to these creatures. My research suggests several high-profile security breaches previously attributed to master spies actually involved Key Cracker deployment. Their natural abilities surpass any human lockpicking technique.

Behavior and Diet

Unlike other solitary City Crabs, Key Crackers display complex social behaviors. They form cooperative groups to infiltrate secure locations, using sophisticated coordination to bypass multiple security layers. Their fascination with locked spaces extends to their feeding habits – they deliberately seek out secured food sources, perhaps viewing the challenge as a form of play.

Habitat

These creatures gravitate toward security-rich environments: locksmith shops, maintenance areas, security offices. The highest concentrations appear near high-security facilities, suggesting an almost magnetic attraction to complex locking mechanisms.

Interesting Facts:

  • The Key Kracker’s existence dates back to ancient Egypt, coinciding with the invention of locks. It is believed that they were the original lockpickers that arose alongside human civilization.
  • It is rumored that a man in the early 20th-century in New York once befriended a Key Cracker. The crab would transform into any key at the behest of this man.  The man was known as Harry Houdini.
  • Several famous museum heists share a peculiar detail: locks opened without damage or tampering.
  • The Secret Service switched to electronic key cards after discovering a Key Cracker infiltration in 1975
