Open Lock (Dex; Trained Only)
You can pick padlocks, finesse combination locks, and solve puzzle locks. The effort requires as 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 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.
Check: The DC for opening a lock varies from 20 to 40, depending on the quality of the lock, as given on the table below.
| Lock | DC |
| Very simple lock | 20 |
| Average lock | 25 |
| Good lock | 30 |
| Amazing lock | 40 |
Action: Opening a lock is a full-round action.
Special: If you have she Nimble Fingers feat, you get a +2 bonus on Open Lock checks.
Untrained: You cannot pick locks untrained, but you might successfully force them open (see Smashing an Object).

You can rush an Open Lock attempt, reducing the amount of time it takes to perform the attempt.
Quick Lockpick: You can try to open a lock more quickly than normal. To reduce the time required to open any lock to a move action, add 20 to the DC. For example, opening an average lock normally requires a DC 25 check and requires a full-round action. To open the lock as a move action requires a DC 45 check.
Quickened Skill Checks - Dungeonscape
When making an Open Lock check, you can attempt to reduce the time required to a move action by adding 20 to the DC. For example, a lock that normally requires a successful DC 25 check and takes a full-round action to open could be opened in a move action with a successful DC 45 check.
