picking padlocks

Many padlocks use pin‑tumbler cylinders or double‑locking lever mechanisms. Listings also commonly mention 4‑pin cylinders and dual ball‑bearing or dual‑locking systems designed to resist prying.

Common anti‑pick and anti‑pry features include 4‑pin pin‑tumbler cylinders, dual locking levers or dual ball‑bearing locking, covered keyways and shackle seals, and explicit pick‑resistant or pry‑resistant designs.

Small locks list compact dimensions such as 1.5" × 1.0" × 0.75" and body widths around 3/4 in (19 mm), with short shackles like 7/16 in (11 mm).
