Given their level, it is also probable that even in anti-magic, Haley has a Dex modifier of +5, which at 12th level (15 ranks) and with the -2 for improvised thieves' tools would give a "take 20" score of 38. Just shy of the DC 40. (There's no evidence in the rules that a nonmagical lock with a DC greater than 40 is physically possible, don't forget.)
