Lockpicking is a function of the rogue's level now. No need to skill-up anymore.
This WoW Lockpicking guide will show you the fastest way how to get your Lockpicking skill up from 1 to 400<. If you are low on gold, I recommend you to try this Gold Making Guide, it can help you to make loads of gold. If you are still leveling your character or you just started a new alt, I recommend you to use a leveling guide. You can level your character from 1 to 80 in 7 days with this guide. My personal record is 4 days 5 hours played time, but it was with heirlooms. The basic formula for your maximum lockpicking skill at a particular level is (5 * level). Here is a list of Junkboxes you can get with Pick Pocket. You can train your lockpicking skill with these too, however in this Lockpicking guide, I will mostly use Footlockers and Doors.
1 - 100These chests below respawn really quickly. Skill up from 1 to 100 will be really easy. Horde:
- [Buccaneer's Strongbox] - These chests located on a ship near Rachet in The Barrens.
- [Burial Chest] - Blood Elves can try this one
- [Practice Lockboxes] - Redridge Mountains
100 - 170The Rogue poisons quests for Horde and Alliance are the best and easiest way to level up to 170. As of patch 3.3 you can no longer gain skill ups If you've already finished the quest. Horde:
- [Gallywix's Lockbox] - The Barrens
- [Duskwood Chest] - Westfall
170 - 225Now you have to go to Badlands - Angor Fortress. You will find two kind of footlockers there, you will need a lockpicking skill of 175 to open the [Dentened Footlocker].
225 - 250Go to the middle Searing Gorge, it's near Badlands and go inside the caves, the Footlockers will be there. Now you can try to Pick Pocket mobs too, because the [Sturdy Junkbox] you will find turns grey only at 275.
- [Dented Footlocker] - There are two kind of Footlockers with the same name, one of them turns green at 250, the other turns green at 275
250 - 300Go to Tyr's Hand in Eastern Plaguelands. Pickpocket the mobs and find all of the [Scarlet Footlockers]. In the time it takes to take a full circle of Tyr's Hand, the starting point will be pickpocketable and have boxes respawned.
300 - 325
- [Wicker Chest] - Zangarmash
325 - 385
- [Dented Footlocker] - Nagrand
385 - 400[Reinforced Junkboxes].
