The MyMetraKey (MMK) app gives you the freedom to remotely book, use and manage your Metra smart locker via your smartphone. With one click your locker will unlock and the locker doors will spring open (or unlock, in case of using Metra's push-open smart lock). Remote, touchless and secure. Almost magic like. The MMK gives total freedom to both staff and management. Pre-book/allocate a locker to have one waiting for you on arrival, assign cleaning and/or maintenance of your lockers, and also open your locker for other staff members when working remotely (or when on a well-deserved vacation). Use the MMK app in your office, school, hospital and elsewhere as a sole 'key' for your locker or in combination with your access card/badge. The MMK app can be used with personal and shared/group lockers (when you have access to a group locker). The MMK app is suitable for all working and other environments, from traditional to highly dynamic ones (ABW).
