Lose your room keys? There’s an app for that at Cromwell Las Vegas

Never lose your room keys again. The boutique hotel Cromwell Las Vegas launches a new mobile app that acts like a key to unlock hotel room doors.

The 188 rooms at the resort that also houses Giada De Laurentiis’ first restaurant now have eKey. It’s an app with an access code tied to a guest’s mobile device (iOS only) and reservation.

Guests enter their ID number and then place their device next to the lock to open the door. The app also activates the hotel’s elevator.

Eventually guests will be able to communicate with valet services, housekeeping, in-room dining and more. They’ll also be able to check into the Cromwell through the app instead of waiting in line at the front desk.

All nine Las Vegas resorts under the Caesars Entertainment umbrella plan to offer the app soon.

Now guests will have to be concerned about losing their cellphones.
