While "copying a high-tech key from a blurry cellphone picture" sounds like the kind of thing only an Oceans 11-style super thief could do, it's actually dead simple. This company will make you a new house key, same-day, from a picture:
"And please, PLEASE don't sue us if your house was broken into."
At least, they used to. Now they're closed to the public "to focus on our enterprise customers." They don't explicitly deny that sex criminals were snapping photos of you getting your keys out in a parking lot, then using them to break into your house and masturbate into your shampoo bottle -- so we are forced to assume that's exactly what happened. Either way, their explanation for why "surreptitious duplication" isn't a problem basically boils down to, "It's so easy to copy your keys, no criminal would even bother to use us."
