Visual Master Key Management
In facilities with thousands of keys, color-coding prevents user confusion and speeds up emergency key identification.
Engineering & Ergonomic Integration
- Molded Polymer Inserts: Key bows incorporate interchangeable colored polymer chips (Red = Emergency GGMK, Blue = Floor Master, Green = Public Area, Yellow = Contractor CK).
- High-Contrast Laser Engraving: Direct fiber laser marking of alphanumeric system codes (e.g.
MK-L2-04) and sequential issue numbers on the nickel-silver key bow. - Tactile Indicators: Raised blind dots on master keys for low-light identification.
Frequently Asked Engineering & Selection Questions
