Master Key Systems: A Complete Guide for Business Owners
Everything you need to know about master key systems for your commercial property.
A master key system is one of the most effective ways to manage access in a commercial building. Here's your complete guide.
How Master Key Systems Work In a standard lock setup, each lock has one unique key. In a master key system, locks are pinned so that individual keys (change keys) open specific locks, while a master key opens all of them.
Levels of Master Key Systems - Simple master: One master key, multiple change keys - Grand master: A hierarchy with sub-master keys for departments and a grand master for building management - Great grand master: Multiple levels of hierarchy for large facilities
Benefits for Businesses - Reduced key carrying for managers - Easy access management by department - Quick rekeying when employees leave - Better security tracking - Cost-effective compared to electronic systems
Best Practices - Use restricted keyway locks so keys can’t be duplicated without authorization - Keep a detailed key log - Rekey change keys when employees with access leave - Limit the number of master key holders - Review the system annually
Cost A basic master key system for a small office (10-15 doors) typically costs $300-$600 for hardware and setup. Larger systems scale accordingly.
