Lock Picking and Bypass Techniques Flashcards

Which lock picking technique involves applying light rotational tension to the plug while manipulating pins individually?

Answer: Single Pin Picking (SPP)

Single Pin Picking (SPP) applies light tension to the plug while individually lifting each pin to the shear line.

What is the purpose of a tension wrench when picking a pin tumbler lock?

Answer: To rotate the plug slightly to create a shear line offset

The tension wrench applies slight rotational pressure to the plug, creating a ledge that pins can set on as they reach the shear line.

Which bypass tool is specifically designed to slide between a door and frame to retract a spring latch bolt?

Answer: Loid / credit card tool

A loid (or shim/credit-card-style tool) slips between the door and strike to push back an unguarded spring latch bolt.

What is 'bumping' in the context of lock picking?

Answer: Using a specially cut bump key struck with force to momentarily bounce pins above the shear line

Bumping uses a bump key cut to the deepest bitting, struck with a mallet so kinetic energy launches driver pins above the shear line long enough to rotate the plug.

Which picking method uses a serrated pick moved rapidly in and out of the keyway to randomly set multiple pins?

Answer: Raking

Raking uses a serrated or wavy pick moved quickly in and out while applying tension, relying on random pin setting rather than precision.

What term describes the picking-resistant feature where pins have a spool or mushroom shape to create false sets?

Answer: Security pins

Security pins (spools, serrated, or mushroom) create a false set when picking, causing the plug to partially rotate before binding again.
