Hospitality Access Tier Structure
Large luxury hotels structure mechanical and electronic keying into 5 strict operational tiers:
- Guest Key (GK): Operates only assigned room.
- Housekeeping Maid Key (MK): Operates all rooms on a single floor during work shifts.
- Building Master (GMK): Operates all guest rooms across the entire hotel.
- Emergency Master Key (EMK): Overrides thrown privacy deadbolts during safety emergencies.
Frequently Asked Engineering & Selection Questions
Q1: How do hotel master key systems handle room privacy deadbolts?
Standard maid master keys are blocked by thrown privacy deadbolts, but a high-tier Emergency Master Key can mechanically override and open the door.
