Lockpicking
From AoP Wiki
Lockpicking is not a standalone skill in the game. Instead, its effectiveness depends on your other support skills: Outdoorsman, Science, and Engineering.
To use Lockpicking, press the hotkey 2 (the default Lockpicking hotkey) and click on a locked container. You must also have a Lockpicking tool in your character's inventory. The most common tool for that job is a Clip, which can be looted throughout the Core. More advanced tools provide bonuses to your Lockpicking skill.
Your Lockpicking skill is calculated using the following formula:
Example: A character with 100% Outdoorsman, 50% Science, 150% Engineering and using a Clip will have a Lockpicking skill of 110% (0,2 x 100% + 0,3 x 50% + 0,5 x 150% + 0%).
