This next kind of lock is the kind you are likely to find on diaries, mailboxes
or even garbages and ashtrays in public places. Due to its small size it's
extremely hard to lockpick but is also very weak.
This kind of little lock is very easy to open.
The trick is that you don't actually need to lockpick it. Precisely because of
its small size, the side of the lock is drilled with holes during manufacturing
process and the pins and springs are inserted in the holes. A small piece of
metal is then set in place on the side keeping the springs and pins from falling
out, and like you can see in the picture below the metal plate is held in
place by nothing but pressure from the side of its socket.
You can see the border of the metal plate.
I discovered that it's very trivial to open the lock by simply pushing hard
with a very small screwdriver or another tubular piece of metal on the first
pin of the lock.
Push hard, that way.
The pin will compress the spring behind it and will push the metal plate
right out of its socket.
The metal plate on the side of the lock will come right out.
Now if you really want to have fun, just play with the pieces a little, the whole lock will quickly come apart. I am sure you will find your own way to do it pretty easily, because I did.
