Key bumping is a [[covert entry]] technique used to quickly open [[pin-tumbler]] based [[lock]]s. Key bumping uses a modified [[key]] to create a kinetic energy transfer between top and bottom pins in the lock. Essentially, top pins are "bumped" above the [[shear line]], allowing the [[plug]] to rotate.
The Gemini is a [[UL 437]] rated [[dimple]] lock designed by [[KABA]]. The Gemini uses three rows of dimple pins oriented at 4, 8, and 12 o'clock. The Gemini is one of the few pure [[pin-tumbler]] locks that is protected against [[key bumping]] by design.
