Ok, if you read it on the internet it MUST be true.

Go ask 100 locksmiths, new ones old ones, everyone you can find.
Your chances are better at winning the powerball than finding one that will tell you he can pick a Medeco.

The true pro thieves, would rather go thru what ever it was holding. per say a medeco on a door, the wall, or door would be easier.
But you can believe anything you wish. After all if you look hard enough, you can find something written on the web that will agree.
