Use a mobile device as a secure key dormakaba BlueSky Access is a cloud-based mobile access key delivery system available for hotels and multifamily housing, student housing, market-rate apartments and senior living properties. It merges security and convenience for the mobile minded traveler or dweller in order to enhance the access experience. The delivery of a key to a mobile device (phone, tablet) is enabled via LEGIC Connect, a service that operates in a highly-secure and scalable data center. Once notification has been received and the BlueSky Access app has been installed, the mobile access key is sent to the app on that mobile device, allowing entry to those doors or areas access to which authorization has been given. The BlueSky Access app is available for use only in properties equipped with dormakaba contactless electronic locks that have been equipped with a dormakaba Bluetooth Low Energy (BLE) radio antenna. Hotels With the BlueSky Access app on a mobile device, guests can bypass the front desk check-in process and go directly to their room as well as gaining access to any authorized common area in the hotel requiring a room key. Residence With the BlueSky Access app on a mobile device, residents can securely lock and unlock unit doors and other amenity areas within a property to which authorization to enter has been given.

They can be installed on a variety of door types and locations giving properties a flexible, secure choice of entry options. BLE-enabled door locks and access controls allow an authorized user to place a compatible mobile device (smartphone, tablet) with the BlueSky Access app near a corresponding sensor on the door lock. The sensor reads the BlueSky Access key, the lock system communicates with the property management network, and determines whether the unique, encrypted code conveyed by the phone is on an approved "pass" list. If so, access is allowed, and the entry is recorded for audit purposes.
