In America, people without locksmith licenses can't legally buy bumpkeys, sadly. If I had a problem that a locksmith could solve with a bumpkey, I'd be quite annoyed that my payment to him is essentially a government subsidy coming out of my pocket.
Not true, this depends upon your jurisdiction. Anyone wondering if it is legal where they live should check their state and local laws.
I've been told by locksmiths that lockpicking tools are illegal in my state, yet no one can point out where state law says this. Thats because its not illegal here. Locksmith isn't even a licensed profession here.
Shouldn't we then also consider that payment to cover the value of the things that would have been stolen from you if any random thief could easily/cheaply get a bumpkey? Who knows how those balance out, but if we're going to count the costs we should count the benefits, too.
