Lock picking manipulates the internal components of a lock to open it without the correct key. While it requires skill, quality locks with security features make picking much more difficult.
How Lock Picking Works
Standard pin tumbler locks have spring-loaded pins of varying heights. The correct key pushes each pin to the exact height needed to align at the shear line, allowing the cylinder to rotate. Lock pickers use tools to manipulate pins one at a time while applying rotational pressure, exploiting manufacturing tolerances that allow pins to set individually.
Common Picking Techniques
Single Pin Picking
Manipulating one pin at a time while maintaining tension - takes skill and practice.
Raking
Rapidly moving a serrated pick through pins while applying tension - faster but less precise.
Bumping
Using specially cut bump keys with striking force (covered in another article).
Pick-Resistant Features
- Security pins: Spool, serrated, and mushroom pins catch and bind during picking attempts
- Tight tolerances: Precision manufacturing reduces the gaps pickers exploit
- Sidebar mechanisms: Require additional elements to align beyond just pins
- Anti-pick shields: Block tool insertion
Recommended Pick-Resistant Locks
Look for UL 437 rated high-security locks from manufacturers like Medeco, Mul-T-Lock, ASSA, or quality residential options from Schlage and Kwikset with security pins.
