When the power goes out, that means your garage door does not open either. Usually the power goes out at inopportune times, like during the middle of the night when you need to get up early for a work presentation or hurry out of town to catch a flight. There are a few things you can do to ensure you will be able to open your garage door even when the power is off.

  1. Enter your garage through the service door if your garage is not connected to your home. No power means your keyless entry will not work either, sorry!
  2. Pull the red cord on the operator trolley to disconnect the opener from the door.
  3. Open the door by hand using the handle on the inside of your garage door.
  4. Pull your vehicle out of the garage
  5. Close the door using handle inside the garage. DO NOT CLOSE THE DOOR FROM THE OUTSIDE BY PULLING IT DOWN WITH YOUR FINGERS BETWEEN THE SECTIONS! YOU CAN SERIOUSLY INJURE YOUR FINGERS! Engage the slide lock if you have one to lock the door.
  6. When the power comes back on, with the door in the closed position, push the wall button to engage the opener and you will hear a “click.” This is the draw bar reattaching to the opener rail. The trolley should be re-engaged and ready to open your door. Let the opener fully open and close your garage door one or two times to re-set the limits.

Some LiftMaster opener models have an optional battery backup. This ensures you can open the garage even when the power is out.
