This will only work when logged in as a registered user, and your administrator has given you access rights to a door. To check this navigate to the "My Profile" screen and scroll down to the "AG1 Door: " etc. section, a door and a schedule are listed next to any of these four options the unlock screen will work. If a door is not listed in this screen contact your onsite administrator for access to the desired door.
While in the "My Profile" screen, toggle the "Keypad Mode is: " slider. If desired to use the unlock screen as a priority, gray the slider out, it will now say "Keypad Mode is off", then select save.
Now you will have to close the enclave completely and reopen it, when you login, you will be directed straight to the unlock screen.
