Keyless room entry available at Starwood hotels Starwood Preferred Guest has launched SPG Keyless, a mobile, keyless entry system allowing guests to use their smartphone as a key. Rolling out to Aloft, Element and W Hotels around the globe, SPG Keyless is debuting in 10 hotels in markets including Beijing, Hong Kong, New York, Los Angeles and Doha. To use the keyless service, SPG members must register their phone on the SPG App and allow push notifications. After securing a reservation at a keyless hotel and approximately 24 hours before arrival, SPG members are invited to opt-in to SPG Keyless. Guests will receive a push notification noting that they are checked in and the SPG App will update with the room number and bluetooth key when the room is ready. Upon arrival at the hotel, the guest can bypass the front desk (where available) and go directly to the room. After ensuring bluetooth is enabled, the guest opens the SPG App, holds the smartphone to the door lock, waits for the solid green light and enters the room.
