From publisher blurb:
I search for traps, and then I pick the lock.
The next time one of your players utters the above frequently heard statement, reach for one of the dozen locks in this PDF written by Ari Marmell. From the devouring lock to the taunting lock, the locks in this PDF will surprise -- and sometimes terrify -- your players.
Each lock includes all of the necessary game information and is ready to be dropped into the next door in your dungeon. With Lions Den Press: Magical Locks your dungeons are a little more interesting.
