This WoW Forever Lockpicking leveling guide will show you the fastest way to level Lockpicking from 1 to 300, with the best place to pick locks for each skill range.
Max Lockpicking Skill by Level
Your Lockpicking skill can't go higher than 5 times your level, so you have to level your character to level Lockpicking. This is the level you need for each part of the guide:
| Your level | Max Lockpicking skill |
|---|---|
| 20 | 100 |
| 30 | 150 |
| 40 | 200 |
| 50 | 250 |
| 60 | 300 |
1-100
Go to the ship near Ratchet in The Barrens. The Buccaneer's Strongboxes there respawn after a few seconds, so even two rogues can skill up there at the same time. They are inside the ship, at the spot marked on the map below.
There is another chest at the bottom of the ship called The Jewel of the Southsea. Don't open it if you are low level, because it spawns a mob that will kill you.
There are a bunch of Practice Lockboxes in Redridge Mountains, north of Lake Everstill. They respawn really fast, so you can get to 100 there easily.
100-150
Go to Zoram Strand in Ashenvale and look for Waterlogged Footlockers along the shore, on land.
150-200
Go to Angor Fortress in Badlands. There are two kinds of footlockers there, the Battered Footlockers upstairs need 150, and the Dented Footlockers downstairs need 175.
Don't bother pickpocketing the mobs there, because their boxes are too low level to give any skill.
200-250
Go to The Slag Pit, the cave in the middle of Searing Gorge. There are a bunch of footlockers inside, and you should also pickpocket the mobs there, because they can have a 
Sturdy Junkbox.
Stay on the lower part of the Slag Pit until 225, because you can't open the lockboxes on the upper part before that.
250-300
You can level the last 50 points in the Blackrock Depths (BRD) dungeon.
If you have the 
Shadowforge Key, use Pick Lock on the doors instead of right-clicking them. Right-clicking uses the key, and you won't get any skill.
- After you enter, turn left and unlock the first door.
- Take the first right and open the next door.
- Go left and open the first door.
- Go through the door and interact with the large wooden object sticking out of the ground below the giant gear (The Shadowforge Lock, see the picture below).
Once you picked all 4 locks, leave the dungeon, right-click your own portrait and click Reset all instances, then go back in. You can only enter 5 instances an hour, so you can only get 20 skill points an hour. If you pickpocket a bunch of mobs on each run, you will have enough Heavy Junkbox to reach 300. Or you can just wait until you can go in again.
