content: Has anyone noticed that these cheap locks can all be opened by each other's keys? There are apartment complexes using these cheap locks for all their doors, so that any of the neighbors can open your door with their own key and do God knows what inside the place you rented. You can spend 20 dollars buying one of these lock and key combinations, and if you know which apartment complexes use that brand of keys, you can open every single one of the doors. I learned this the hard way when I found out someone was going through my stuff while I was gone.
