End-of-Life Security Protocol
When a commercial building transitions to electronic access control or commissions a new master key matrix, old mechanical cores must be safely decommissioned.
Decommissioning Checklist
- 100% Key Reclamation Audit: Log and reclaim all issued Master Keys (GMK, MK) against the original commissioning registry.
- Physical Core Destruction: Neutralize retired cylinder plugs by drilling or recycling brass bodies to prevent old keys from compromising perimeter doors.
- Audit Sign-Off: Issue a certified Security Decommissioning Certificate.
Frequently Asked Engineering & Selection Questions
Q1: Why must retired master keys be audited and destroyed?
To prevent unreturned master keys from being used to access the building after new security systems are installed.
