Bump Hammer

Bump hammers allow for fast access through a wide variety of cylinder locks when used in conjunction with bump keys (sold separately in 3-pc or 5-pc options). 

Bump keys are standard key blanks cut to allow for bypassing locks using the bump method. Simply insert the key almost all the way into the lock, then tap it with the bump hammer while applying torque to the key with your non-dominant hand. When done correctly, the key will "bump" all the cylinder pins upward simultaneously, allowing you to quickly turn the key and unlock the cylinder before they reset. 

It's even simpler than it sounds and with a little bit of practice you can open many standard deadbolts and cylinder locks in a few seconds. Only with both in hand can you bump a lock. It's also a great set to keep if you oversee a large facility but don't have a set of master keys, or if you lock yourself out of your home. 

Bump hammers are lightweight, made entirely from high density polymer with a rubber handle, highly flexible, and will stand up to extensive, repeated use. 

These bump hammers are manufactured in the USA.
