What is a “bump key”?
A bump key is a normal key cut to a specific code which can be used as a lock picking tool in some standard pin tumbler cylinders. Lock picks and pick guns require specialist knowledge to manufacture and use, bump keys are more accessible and easier to use which increases the risk of the otherwise professional technique being used for illegal purposes.
What is the “bumping method”?
The bumping method is a non-destructive process used to quickly unlock some standard pin tumbler cylinder locks through the use of a bump key.
How long has the “bumping” technique been used?
As a part of their job function locksmiths and security professionals have known about and used the bumping technique for many years. Operating within an industry code of ethics and true security professionals do not share such security knowledge with the public. The bumping procedure is now taught, discussed and demonstrated publicly on the internet by hackers outside of the security industry. This publicity has created security and safety concerns which security professionals are now working to overcome.
What is the risk of “bumping attacks”?
Because the bumping technique has become public, less scrupulous individuals may learn to bump conventional style cylinders, causing concern about protection from unauthorised entry. Manufacturers and security professionals began taking immediate action to develop bump resistant methods of security when the technique became common knowledge.
