Master Key Systems — FAQ
How does a master key system work?
Each lock is pinned with two shear lines: one for the individual change key and one for the master key. This allows two different keys to operate the same lock while keeping individual keys from opening other doors in the system.
Is a master key system less secure than individual locks?
When designed and installed correctly with restricted keyways, a master key system is highly secure. The additional shear line is a minor theoretical vulnerability, but it is mitigated by using high-quality pins and restricted key blanks.
Can you add new doors to my existing master key system?
Yes, provided the original system was designed with room for expansion, which is standard practice. We’ll reference the bitting chart and pin the new cylinders to fit the existing hierarchy.
