Marriott Power of M
Mobile Key Upgrade
Is your Marriott property ready for Mobile Key 2.0? Symmetry I.T. specializes in GPNS network configuration, Key Flow 2 deployment, and full mobile key activation for franchise and managed Marriott hotels.
We handle everything — VLAN setup, Key Lock server configuration, PMS integration, ServiceNow ticket submission, and lock vendor coordination — so your property meets brand standards without the complexity.
What Is Marriott Power of M?
Power of M is Marriott International's portfolio-wide brand standard requiring all properties — both franchise and managed — to implement Mobile Key. Mobile Key allows Marriott Bonvoy loyalty members to use their smartphone as a room key to access guestrooms and common areas including fitness centers, pools, and business centers.
Marriott mandated that all hotels install and activate Mobile Key certified locks in 100% of guest rooms and common areas. Properties that have not yet completed the upgrade — or are upgrading to Key Flow 2 (Enhanced Mobile Key) — require a certified GPNS LSP to configure the network correctly.
Symmetry I.T. is a certified GPNS Licensed Service Provider (LSP) with direct experience configuring all five Marriott-defined network types and all four certified lock vendors.
