Differ keys
Key System
KD System (Key Differed)
Definition: Each lock has a unique key that works for only one lock.
Principle: Randomizes key coding to ensure exclusivity between keys and locks.
Application:High-securityenvironments(e.g., safes, restricted areas) where unauthorized access must be fully prevented.
KA System (Key Alike)
Definition: A single key can open multiple locks.
Principle: Uses identical key coding to allow crossoperation across multiple lock cylinders.
Application: Ideal for centralized management (e.g., apartment complexes, offices), prioritizing convenience over individual lock security.
MK System (Master Key)
Definition: A hierarchical system where a master key opens all locks, while sub-keys only open specific ones.
Principle: Embeds layeredpermissions into keys, with the master key overriding sub-key restrictions.
Application: Hotels, corporate buildings, or facilities requiring tiered access control.
