    Master Lock Company has a solution to the break-less break-in (where tapping a key with a screwdriver or other tool “bumps” the lock, allowing easy and undetected entry) with its BumpStop Advanced Cylinder Technology.

    Even buildings with key-card access, security cameras, and doormen run the risk of uninvited guests bumping individual units.

    Master Lock’s BumpStop technology exceeds the highest ASTM Standard level lock bump criteria. 

     Compared to alarm systems and similar security measures, locks such as these provide the most affordable lock bumping solution available today.
