Best practice master key systems specification
The best practice for master key systems security has changed (see our guides for hospitals and education). For many organisations the need for security has increased and convenience has to be sacrificed:
- External and Internal Masterkeys have replaced a single Masterkey (see health system design and education system design)
- Patented Masterkey designs are more commonly specified than simple ‘unsecured' systems
- Construction keying is used to avoid security being compromised during a buildings construction phase
