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 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 | Lock | DC | |
|---|---|---|---|---|
| Very simple lock | 20 | Good lock | 30 | |
| Average lock | 25 | Amazing lock | 40 |
Action: Opening a lock is a full-round action.
Special: If you have the 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).
