Open Lock

Player's Handbook v.3.5 (PH)3.5

Key Ability: DEX
Trained Only: true
Armor Check Penalty: false

You can pick padlocks, finesse combination locks, and solve puzzle locks. The effort requires at least a simple tool of the appropriate sort (a pick, pry bar, blank key, wire, or the like). Attempting an Open Lock check without a set of thieves' tools (page 130) imposes a -2 circumstance penalty on the check, even if a simple tool is employed. If you use masterwork thieves' tools, you gain a +2 circumstance bonus on the check.
