No, that is not currently a function of the Keychain Remote. However this can be done using the Frontpoint App.
Arming and disarming your system is quick and easy through the Frontpoint app. Secure your home by arming right from the app; if you frequently forget to arm your system after you've left, create arming reminders that will send an alert if your home is left disarmed. Once you've arrived home, disarming your system is quick, so you can avoid accidentally triggering a false alarm.
Follow the step by step guide below to see how to do it in the App.
Tap "System Disarmed" on the Frontpoint app home page within the "Security System" menu.
Select your preferred arming options, then tap "Arm (Stay)" or "Arm (Away)" to arm your system. For an explanation of the arming options, see below.
The system is armed with no exit delay beeps from the panel.

Bypasses any sensors that are currently open or reporting a trouble condition (A bypassed sensor is not actively monitored and will not trigger an alarm).
Bypass Specific Sensors
Select specific sensors you would like to bypass once the system is armed(A bypassed sensor is not actively monitored and will not trigger an alarm).
To disarm the system, tap "System Armed" on the Frontpoint app home page within the "Security System" menu, then tap "Disarm".
