$150 for keyes
$500 court costs
$500-1000 in fines
$2000 to a lawyer (a cheap one)
1 night in jail.
My math puts that at a minimum of $3,150 plus a night of fighting off drunks at the county hoosegow.
What is worse is the hacker community (who love a good puzzle) will quick post detailed instructions on how to make these.
The photo of the keys is detailed enough to measure the depth of each cut required. In fact, a 3d printer will make it even easier to produce, since some of those keys may be hard to find blanks for.
Hackers recently did this for a high security handcuffs.
