Bumping is a method that existed for years, but only in the last few years it was been exposed to the public’s eye, mainly through the internet.
A bump key is actually a key that is cut to the highest position, when you hit that key some pins will jump and with the perfect timing it would be possible to turn the plug. Some very high security locks surrender to this method.
Here is how it works..
This is a Linca lock from Spain, this lock has 5 pins and a side bar
A Fab lock that is almost impossible to pick
A Yardeny lock from Israel with 10 pins
Kaba 12 pins lock
A 7 pins Herman dimple lock
Magnum 7 pins dimple lock from China
The world’s smallest bum key? Only 3 pins
A Dom lock
