Lockpicking Guide from 1-300
100-125 - You can pick the Polly quest chest (Horde LP Quest chest), several people have reported this now turns grey at 125.
100-170 - You can use either of the chests in the Poison quests (Alliance OR Horde) you get at later levels. You will have to click on your lockpicking skill first, then click the chest. These chests will turn grey at 170 skill.
*Note: For the Polly/Poison Tower chests: You NEED to activate (CLICK) your lockpicking skill icon first, then (CLICK) on the chest as your cursor will not change automatically like it did during the quest or before it.
The boxes at Durnholde keep in Hillsbrad should stay green for you until you get to 175.
175-225 - Pickpocket mobs for Sturdy Junkboxes or Steel Lockboxes. Several mobs drop them, check thottbot and pick the best location for you. I recomend mobs in instances, that way you can pick it clean, reset the instance, then go to town again. You can also pick doors in instances at this range. I personally picked the door in the Scarlet Monestary cathedral from 180-225 one day by repeatedly resetting the instance.
225-280 There is no real easy way that I've found to skill this range other than to keep doing junkboxes. You can use the gates in the NE corner of Searing Gorge, but there is no reliable way to reset them (see notes below for more information). Also opening lockboxes in your faction's major city will get you skillups.
280-300 There are 3 doors in Blackrock Depths that are very close to the zone in that you can use to skill up this. Head in, go left, pick the first 3 doors, exist, reset. Several people have stated this lock is orange (pickable) as low as 255. I can't currently comfirm.
Battered Junkbox (Orange: 25 Grey: 100 )
Dropped Chest - These are extremely random, so don't try to camp them.
Heavy Bronze Lockbox
Doors in the normal world (aka not in instances) are usually on some sort of timer. In other words, you can't repeatedly pick the same door over and over again for skillups. The mechanism of the timers are not well known. Some people say if you pick something else (anything else) in between attempts that it will reset some timers. Others say that if you pickpocket a mob, or kill a mob, or so something else, that this will reset the timers. It may be different for every door. Suffice to say that reset an instance always (to my knowledge) resets any doors inside, so use that method when you can. I am leaning towards the pickpocketting theory for now.
Gnomeregan (Orange: 150 Green: 200)
Most of these are chests used in quests that you can pick after you complete the quest. Note that you will probably need to activate your picking skill first, then click on the item as your cursor will not change automatically like it did during the quest or before it.

List of things that increase Lockpicking:
Various notes and other information:
1. Alliance rogues using the Klaven tower (Posion quest) chest: I just did this at 39, go to Westfall to where the poison quest is at, top floor, Klaven can take me down to half health at 39 if I don't dual-ambush so he kinda hurts. Hopefully you can also be outside his aggro range to practice. To do this just go behind his table (after he spawns he walks around the top of the tower, wait until he is done and ends up a bit away from you), there should be two chairs, jump over the chair closest to the chest and from behind the chair pick the lock. Don't worry about Touch of Zanzil: a death or Jungle Remedy from STV or cure poison from a high enough player should make it all good. Note that you need to activate your picking skill first, then click on the item as your cursor will not change automatically like it did during the quest or before it.
2.You can skill up 8 times on the doors to SM, there are 4 doors, 2 inside instances and 2 outside. They are on timers which can be reset.
Library: Chest in a cubby before the Gallery of Treasures, guarded by 3 mobs. Another chest that spawns in one of the hallways close to Doan himself, guarded by typically 2 mobs + one roamer.
Armory: Chest either in the Training Grounds (guarded by 2 mobs + 1 roamer) or inside the first part of the armory (guarded by 2 mobs + 1 roamer.) Can't remember location of other chest off the top of my head.
Cathedral: Chest on either the left or right side of the fountain. Another chest that spawns either by the monk guarding Fairbanks' hiding spot, or spawns on the other side of the cathedral (guarded by 3 mobs + 2 that roam close but may or may not aggro.)
5.South of Ratchet along the coast a short way is a beached pirate ship. No pirates around ship, they are camped south of it. Bit tricky getting the jump up onto the prow of the ship so you can get onboard, but can try repeatedly with no hassles
