**IMPORTANT: The Internet Gateway cannot be registered through Alarm.com if it is already registered through MyQ/LiftMaster. The Internet Gateway must be removed from the user's MyQ account before attempting to register it to Alarm.com.


Install the MyQ Control Panel

  • Disconnect all electrical power to the garage door opener.
  • Remove the existing door control from the wall. Note the polarity of the wires connected to the existing door control. Label the wires appropriately (Red/White).
  • Disconnect the wires from the existing door control.
  • Connect the wires to the new MyQ Control Panel.


  • Mount the MyQ Control Panel to the wall.
  • Reconnect power. The yellow command LED (in the center of the MyQ Control Panel) and the red learn LED (above the learn button) blink quickly for up to five minutes as the MyQ Control Panel recharges. When the MyQ Control Panel is operational, the yellow command LED is solid.
  • To test the control panel, press the push bar to activate the garage door opener.

Connect the MyQ Internet Gateway

  • Connect Ethernet cable to router and the Internet Gateway.
