Project Objective
Convert all existing lock cylinders on common-area doors to a unified Grand Master Key (GMK) system to enhance security, simplify key management, and maintain compliance with all relevant Dubai regulations.

Survey & Documentation

·       Conduct full site survey of all common-area doors (entrances, service rooms, fire exits, utility rooms, etc.).

·       Record door type, fire rating, existing hardware, and lock type.

·       Identify fire-rated and emergency exit doors requiring Dubai Civil Defence (DCD) approval.

System Design

·       Develop Master Key Plan (GMK, optional sub-MKs).

·       Submit sample cylinder & key for client approval.

·       Recommend restricted/registered key profile for duplication control.

Materials & Standards

·        Supply high-quality Euro/mortise cylinders with anti-snap/anti-drill protection.

·        Fire-rated doors: install DCD-approved fire-rated cylinders and panic hardware.

·        Keys: uniquely serialized, sealed, and registered.

·        Comply with Dubai Building Code (DBC), UAE Fire & Life Safety Code (DCD), Dubai Universal Design Code (for accessibility), and SIRA requirements where applicable.

Installation

·        Remove existing cylinders and install new GMK-compatible cylinders without damaging doors/frames.

·        Ensure single-action escape for all fire/egress doors remains unaffected.

Testing & Commissioning

·        Test each lock with assigned MK(optional) and GMK

·        Verify compliance of fire/egress doors with DCD life safety requirements.

·        Provide corrective actions for any defects.

Handover Deliverables

·       Master Key Chart (door schedule with cylinder serials & key hierarchy).

·       Manufacturer datasheets & certificates.

·       Fire/panic hardware approvals (where applicable).

·       Warranty documents and key register.

·       Sealed GMK copies (3 only) handed over to client’s authorized custodian.

Acceptance Criteria

·        All locks operate with MK(optional) and GMK smoothly.

·        Fire/egress doors remain compliant with DCD/UAE Fire & Life Safety Code.

·        Client signs off Master Key Chart, documentation, and receipt of sealed GMKs.
