How to unlock the No Tumbler Fumbler achievement in Fallout: New Vegas - Definitive Guide
Anyways you will want to level up your Lockpick skill by spending your points you get by leveling up. I always try to throw 2-3 points on it every level. You should try to get it to at least 75 as soon as you can.
Here are the thresholds for the lockpick skill:
25 - Easy
50 - Average
75 - Hard
100 - Very Hard
Good luck!
An achievement that simply must be done over time. Remember to take it slow, as each bobby pin has a 'health' bar such that if you guess wrong you can stop before it breaks. Should you fail often, you might want to invest in the Infiltrator (Perception 7, Lockpick 70) perk which lets you repick a broken lock one more time. This achievement can easily be done with "Hack the Mojave," as many locked doors have a terminal next to them that can unlock the door. If you do them simultaneously, access the terminal first, hack it, but then unlock the door manually instead of through the computer.
To pick a lock, to begin with you'll need a bobby pin in your inventory. The rotates the angle of the bobby pin over a 180° arc, and the turns the lock with a screwdriver. If the bobby pin is in the correct position, the lock will open. If not, then the closer you are to the correct position the further the lock will turn before it stops. Release the immediately when this happens, and adjust the position of the bobby pin. If you're getting closer, the lock will turn further than before. If not, try the other direction.
To improve your chances of picking a lock, ensure that you have a high Lockpick skill as well as a high Perception stat. If you find yourself breaking a lot of bobby pins, remember that you can cancel the lockpicking attempt at any time. After three tries to turn the lock have failed, the bobby pin will usually break on the fourth attempt, so if you're not sure you've got the right spot, don't be afraid to pull out. (That's what she said) Keep track of your progress on the Stats screen of your Pip-Boy.
