Additionally, you can send a check-out request from your mobile key screen and rate your hotel stay from within the app. With the latest update, OpenKey has redesigned the user experience to create a fast, simple, and secure experience for hotel guests. The process of getting your mobile key is straightforward - just request a mobile key in the app, receive a text message with a verification code, input your mobile number and verification code, and press "get key."

Overall, OpenKey is a convenient and secure way to access hotel rooms with your smartphone.
