I've come across so many tech people who are so good at picking locks that they could become locksmiths. I'm not sure what it is, but there's a strong correlation between tech and lockpicking. I myself have been picking locks -- recreationally, I should add -- for years, and I find it one of those relaxing things.
Some people do crosswords or sudoku, I pick locks.
Now, you don't want to be picking the locks on your doors, so I recommend getting a training lock, and one of the best I've come across is the Multipick Training Cylinder.
I love it because it has cutaways so you can see how a lock works, you can customize it to make it easier to harder, and it offers even the experienced lockpicker a degree of challenge.
I've got one on my desk, and it's offered hours of fun. It's the perfect desk toy!
Note: This kit does not come with lockpicks.
