Keying Terms

Step 1: Determine the size of the master key system. Consider the following:

  • Current users; often consulting an organizational chart can help determine existing needs.
  • Future requirements; commonly, a 10 year life of a master key system is recommended:
    • Employee turnover & termination
    • Increased staffing
    • Building expansion
    • Lost keys

Step 2: Determine whether a padlock only or padlock & door lock (Door Key or Interchangeable Core) Master Key System is best for your organization.
