OpenKey allows properties to provide a superior experience for their guests using mobile keyless room access using smartphones. Before guest arrival, OpenKey retrieves reservation data from Mews which they use to communicate with guest. The guest will receive an email or text message with instructions on how to download the app which enables bluetooth communicate with the door. OpenKey can integrate with any electronic lock on the market by adding their Universal BLE Upgrade Module to your existing lock. OpenKey also supports direct integrations from Assa Abloy (VingCard), Dormakaba (Saflok), Salto, MIWA, Hafele, and BeTech.
