Low Tech Access Control: Restricted Keyways

Author: Brian Rhodes, Published on May 20, 2015

Access control is sometimes as simple as good management of mechanical keys and locks. While the market is jammed packed with electronic systems that make management of users and their credentials easy, sometimes the most effective step is keeping copies of keys out of the wrong hands.

Restricted or Proprietary keys are often overlooked, but can be effective in improving door security and access control. Inside, we explain:

  • Keyway profile variations
  • Why Do Not Duplicate statements are useless
  • Differences between Unrestricted vs Restricted vs Proprietary 
  • Strengths and Weaknesses of these approaches
  • Common Providers and Pricing
