Step-by-Step Guide to Creating a Master Key System
Follow these steps to design secure, scalable master key systems with confidence.
Step 1: Plan Your Full System
Always create the complete master key system upfront. Even if the client only needs part of it now, building the full system allows easy future expansion for new buildings or facilities. Using the groups you need while leaving unused groups is safe and prevents headaches later.
Step 2: De-Master Cylinders
Before adding new master pins, de-master cylinders to remove old master pins. This prevents unwanted stacking of pins and ensures that new keys will function correctly without accidental access.
Step 3: Manage Cross Keying
Intentional cross-keying requires careful planning. MasterkeyPro automatically detects and manages stacked pins, ensuring security is maintained while allowing shared access where necessary.
Step 4: Create Secure Master Keys
Mix deep and shallow cuts with even and odd cuts. Avoid predictable patterns. Using a combination of even and odd cuts prevents keys from opening unintended locks if the wrong change key is inserted and slightly shifted. MasterkeyPro automates all calculations for correct pinning and key levels.
Step 5: Review and Implement
Use MasterkeyPro reports to review your system. Ensure all conflicts are resolved and all master keys work as intended. Generate pinning charts, detailed reports, and documentation for installation and client records.
