What Makes a Lock High-Security
The term high-security is not just marketing. It refers to a specific combination of features that standard pin tumbler hardware does not include:
- Pick resistance through spool pins, serrated driver pins, or sidebar mechanisms that defeat standard picking techniques
- Bump resistance through pin geometry or alternative operating mechanisms that cannot be manipulated by bump key impact
- Drill resistance through hardened steel inserts or anti-drill plates protecting the cylinder core
- Restricted keyway so that key blanks are not available at hardware stores and duplicates require authorization
- Independent certification such as ANSI Grade 1, UL 437, or equivalent ratings that verify tested performance
Brands We Supply and Install
We work with the leading high-security lock brands in the residential and light commercial market:
- Medeco combines a patented rotating pin design with an angled keyway to deliver pick resistance and key control in a package that fits standard residential door prep
- Mul-T-Lock uses a telescoping pin-within-a-pin design that provides exceptional pick and bump resistance and is widely used in high-value residential applications
- ABLOY disc detainer locks operate on an entirely different principle from pin tumbler locks, making them inherently resistant to picking and bumping
- Schlage B-Series Grade 1 deadbolts represent a strong balance of security and cost for homeowners who want certified Grade 1 performance without moving to a full high-security platform
Cost vs Standard Locks
High-security locks cost more than standard residential hardware. A quality Medeco or Mul-T-Lock cylinder runs significantly more than a Schlage B-series deadbolt. For most homes, a properly installed Grade 1 deadbolt with a reinforced strike plate covers the realistic threat. High-security hardware is the right investment when key control is a priority, when the property contains significant valuables, or when the homeowner wants the maximum available resistance to covert entry.
When the Upgrade Is Worth It
Consider upgrading to high-security hardware when any of the following apply:
- You want verifiable key control so copies cannot be made without your authorization
- Previous occupants or contractors had key access and you cannot account for all copies
- The property stores high-value items or sensitive materials
- You want the highest available resistance to covert entry methods
- You are in a neighborhood with elevated property crime history

Frequently Asked Questions
What makes a lock high-security?
A high-security lock combines pick resistance through advanced pin geometry, bump resistance through design features that standard locks lack, drill resistance through hardened steel components, a restricted keyway that prevents unauthorized key duplication, and independent certification such as ANSI Grade 1 or UL 437 that verifies tested performance.
Can my existing door handle a high-security deadbolt?
Most standard residential doors can accept a high-security deadbolt without modification. The bore hole size and backset measurements are typically standard across residential hardware. We assess your door before recommending any product and confirm compatibility before any installation begins.
Are high-security locks worth the extra cost?
For most homes a quality Grade 1 deadbolt provides an excellent balance of security and cost. High-security locks are worth the extra investment when you want key control, when your home contains significant valuables, when previous occupants had access and you cannot account for all copies, or when you want the maximum available resistance to covert entry methods.
What is a bump-proof lock?
Bump-proofing refers to resistance against bump key attacks, where a specially cut key and a sharp impact manipulate pin tumbler locks into opening. High-security locks resist bumping through spool pins, rotating elements, or sidebar mechanisms. ABLOY disc detainer locks are inherently bump-proof because they use an entirely different operating principle from pin tumbler locks.
Can you duplicate high-security keys at a hardware store?
No. High-security keys use restricted keyways that hardware store cutting machines cannot accommodate. Copies can only be made by an authorized dealer with the correct key blank and the owner's proof of authorization. This key control is one of the primary security benefits of high-security lock systems.
