The Killer Key

This key allows you to “kill” a lock by inserting and turning it. The manufacturer claims that it’s for landlords, but given that their other products are sneezing powder, stink bombs, stain-powder, and powdered capiscum, it’s clear this is meant to be used as a “prank.” Not a prank where someone is fooled and then everyone laughs, but the kind of prank where you ruin someone’s day and don’t tell them who did it.

Anyway, some guy bought one and used it on his own house, so enjoy his one-star review of what happened next.
