Physical security is a top priority, protecting homes and families as well as business assets and employees.  Need to improve your security?  Most homes and many businesses do!  Most locks are economy models that don’t provide as much protection as most people believe.  You can find detailed instructions for lock picking and bumping on the web, and most keys are easily duplicated.  Even from just a photo or photocopy.  It’s surprisingly easy to get inside without any sign of forced entry.  You might not even realize you’ve been robbed until hours or even days later.

Standard keys have a 1-dimensional simple pattern that’s relatively easy to pick or otherwise trick.  But high-security locks and their accompanying keys have special features that resist lock picking, bumping, and drilling.  The locks are hard to defeat, the keys hard to duplicate.  Nothing’s invincible, but they make it too time-consuming and difficult to be worth even trying.  High-security locks are the norm for banks, government buildings, and military facilities, but they’re also common for hospitals, schools, offices, and other commercial buildings. Even homes. You’ll have added peace of mind with a whole new level of security.


Security locks are designed with added features.  They’re built and installed with more rugged materials in a doorknob, deadbolt, cylinder, and other formats.  Their extra-secure features include the following.

  • Restrictive keyways.  Complex and multi-centered, these make picking extra-difficult. 
  • Likewise, unique mechanisms involve elevating, rotating, and interacting pins with sidebars and sliders, plus additional locking elements.  And merely a higher number of pins. 
  • Hardened steel inserts and heavy-duty mounting to resisting drilling and smashing. 
  • High precision construction so that keys must match perfectly.

Thousands of patents cover these innovations.  Leading brands with high-security rating products include Medeco, Mul-T-Lock, CX-5, and Primus.

Keys and Key Cutting

Each line of high-security locks requires uniquely shaped and specially cut keys.  For example, angled cuts disperse the force of bumping and turn thousands of possible cutting variations into millions.  Special patterns limit cross-keying while still allowing complex master keying.  Keys are marked “do not duplicate,” blanks are controlled and tracked, and there are only a limited number of special patent-protected cutting machines.  Need a duplicate or replacement?  You’ll need to present an authorization security card.

Not Just Doors

Besides exterior and interior doors, these superior lock technologies are available for padlocks, security gates, and other applications.  In some situations, an existing lock can be upgraded by replacing just the conventional cylinder.
