Skeleton Pinkie

As a mechagnome you can unlock boxes of your own level. So if you are level 60, you can unlock boxes that are level 60. All you need to do is click the button in your spellbook and your mouse changes in a glowing hand. Click with that hand the locked item.

You can also unlock boxes for other players via the Trade screen.

You do not need to visit a (rogue) trainer or train this ability by unlocking lower level boxes.

Rogues have competition!

Even at very low levels, you'll generally be able to pick stuff you can reach. This means it's actually possible for a mechagnome to pick the door and skip an ambush in Deadmines, where as rogues will have to wait to get their own pick lock, meaning they can't do it.

This does mean it's less valuable to be a mechagnome rogue than other classes, but it's very useful, and there are rare occasions where lockpicking is useful, and you might not always have a rogue, but having a mechagnome could save you the materials needed for a profession-based lock-pick.
