Hyatt Hotels Corp. has introduced at six U.S. hotels room keys in Apple Wallet for World of Hyatt loyalty members, with plans to roll out the technology eventually across Hyatt’s global portfolio, the company announced Wednesday. 

Members staying at one of the participating hotels can tap their iPhone or Apple Watch to unlock guest rooms as well as key card-protected common areas, such as gyms, pools and elevators. They can add their room keys from the World of Hyatt app after completing a reservation. Once added, the room key will be updated to let the guest know when it’s time for check-in, and upon completion of check-in and assignment of a room, Hyatt will activate the key. 

Should a guest need to change rooms, extend a stay or request late checkout, the hotel can update the room key in Apple Wallet remotely. Guests also can check out using the World of Hyatt app, which will deactivate the key.

The six hotels currently offering keys in Apple Wallet are the Andaz Maui at Wailea Resort, Hyatt Centric Key West Resort & Spa, Hyatt House Chicago/West Loop-Fulton Market, Hyatt House Dallas/Richardson, Hyatt Place Fremont/Silicon Valley and Hyatt Regency Long Beach.
