Lock bumping a new threat in break and enter crimes

Supplier News

Bumping has been identified as a new threat in ‘break and enter' crimes and lock manufactures are grappling with ways to minimise its effectiveness or eliminate it, says KGB Security .

Bumping for the uninitiated is the technique of opening a regular, pin-tumbler lock by using a specially modified key. Bumping can be used to open locks currently available in Australia quickly, without leaving any evidence of damage.

Linus Yale patented the pin tumbler lock in 1861, which gave affordable security to the masses. This simple design has remained at the forefront of lock security up to present. However the internet has been its undoing. The first published details, including tutorials showing how to compromise the humble pin tumbler lock, appeared back in 2004. Since this time numerous sites and articles have been posted.

According to KGB Security, in a perfect world the manufactures would have solved this flaw before the problem became public. The break and enter statistics will not increase as result of bumping, only the criminals targets will change. As with any security threat the more you do to prevent it the less likely you will affected by it.

Multiple locks, alarms will certainly deter you from becoming a victim of a bumping break and enter. However the only way the threat your locks being bumped can be 100% eliminated, is by replacing your locks with ‘bump-proof locks' such as EVVA.

Locksmiths are custodians of information they keep safe to ensure the protection both of people and property. New tools and techniques are presented every day that can eat away at the foundations of our society's security when they fall into the hands of the dishonest. The colour printer and scanner has been a boon for the counterfeiters and a thorn for those who seek to protect unauthorised copying.

The bumping technique once possessed by those who wish to master it, has the potential to have negative ramifications, any criminal armed with this skill will also be able to gain entry to almost any pin tumbler style of lock.

In Australia, the majority of pin tumbler locks use less than 30 different key profiles (the shape of the key). Even restricted pin tumbler locks are vulnerable as many distributors do not record adequate details when a sale is made however a restricted profile locks is secure than the standard Lockwood or C4 keyway as it is known in the locksmithing industry.

The following locks are bump-proof:

  • EVVA: High quality Austrian locks since 1918
  • BiLock locks: High quality Australian locks since 1986
  • Abloy disc locks: High quality Finish locks ( Now owners of Lockwood)
