Re: Dump your key locks and go combination
Here's a sport for all you danger-and-adrenaline junkies. For a few dollars you can get a key-in-the-knob doorlock and use it to practice. A lot of these have at least one spooled pin.
Combination locks aren't necessarily better by orders of magnitude, either.
I remember a window sticker that said: "These premises are protected by Smith & Wesson."
Perhaps cunning and vigilance are the best deterrents?
