2 + 2 × Perception + Luck/2

Example: A starting Perception of 5 and Luck of 5.

2 + 2 × 5 + 5/2 = 15

In Fallout 3, your Lockpick skill determines which locks the game will allow you to attempt to pick. Your skill must be at least the lock rating to try, and locks are rated at 25% increments: Very Easy - 0%, Easy - 25%, Average - 50%, Hard - 75% and Very Hard - 100%. Thus, there is little reason to invest more points in this skill beyond the level of lock you want to have access to. If you have the prerequisite skill, picking a lock takes the form of a mini game (see Lock for details).
