one with a file, 10 minutes with a Dremel,
seconds with a key cutting machine
Need a different key for each lock type
Available on E-Bay as “Depth Key”
Set of 8 keys costs $30 – but can be
purchased for as little as $8
Bump Key Tools

Tomahawk is used for bumping
Can also use a screw driver, mallet or other
device to strike the lock

In April 2005, a Dutch television show

Videos started surfacing on the internet in
2006
Television stations use Bump Keys as a
story “You need to know about”

Any lock with vertical pin tumblers is at risk
Most residential homes are vulnerable
Most businesses are vulnerable
Most mail box locks are vulnerable
Counter Measures




Locks that resist bumping are already on
the market
Most require a secondary element
The secondary element is usually
horizontal to prevent gravity of bumping
Some are resistant, while a few claim to be
bump proof

Cost to landlord to install ‘anti-bump key”
locks
One company sells a “bump key proof”
single cylinder dead bolt for $130 per lock
Larger apartment communities may have to
use key cards like hotels and deal with the
hassles
Impact for Law Enforcement



Officers need training to recognize bump
keys and the tomahawk or other tool when
contacting suspects
If responding to a reported burglary without
signs of forced entry be aware of bump
keys
Notify detectives if you respond to repeated
burglaries without signs of forced entry
