How to Open Your Garage Door Manually (When the Power's Out)

    Adam Duce, Limitless Team 25 May 2026 8 min read

    TL;DR — Quick Summary

    To open your garage door manually, first make sure the door is fully closed and the opener is unplugged from power. Pull straight down on the red emergency release cord hanging from the opener trolley — you'll feel the trolley disconnect from the door. Lift the door by hand from the centre using both hands. A properly balanced door with intact springs should feel light (5–10kg of effort). If it feels extremely heavy, stop — your spring is broken and the door is unsafe to operate.

    When the power goes out and your car is stuck inside

    Every Darling Downs storm season we get the same calls — power's out, car is locked in the garage, and the door won't budge from the wall switch. The good news is every modern automatic garage door is designed to be opened manually in exactly this situation. You just need to know where to pull and how to do it safely.

    Step 1 — Make sure the door is fully closed

    The emergency release latch is under load when the door is partly open — the spring is trying to either pull it up or push it down. Releasing the trolley in that state can cause the door to slam in either direction. If the door is stuck part-way, do not pull the cord. Call us instead.

    Step 2 — Locate the red emergency release cord

    Look up at the rail running from your opener motor to the door. The trolley is the moving carriage that pulls the door open. Hanging off it is a short red cord with a red plastic T-handle. It usually sits about 30cm below the rail. On a Merlin, B&D or ATA sectional opener it's roughly one-third of the way back from the door.

    Step 3 — Pull straight down

    Grip the handle and pull straight down with a firm tug. You'll hear and feel the trolley latch disengage from the chain or belt carriage. The door is now disconnected from the motor and free to move by hand.

    Step 4 — Lift the door from the centre

    Place both hands under the bottom edge of the door near the centre and lift smoothly. A balanced sectional or panel-lift door with healthy springs takes about 5–10kg of effort — comfortable for most adults. The door should hold its position halfway up without falling.

    If the door feels like 40kg or more, stop. Almost certainly one of the torsion springs has failed and the door is dangerous to lift further. Read our guide on broken spring repairs and call us.

    Roller doors are different

    Automated roller doors (Gliderol, Boss, Steel-Line GlideRol) don't have an emergency cord — they have a manual override lever or key on the motor housing. Slide or rotate the lever to disengage the motor gears, then use the hand crank socket or chain to wind the door up. Procedure varies by brand — check the sticker on the motor or your installation manual.

    Step 5 — Re-engage when the power returns

    Close the door fully by hand. Now pull the red cord toward the door (not straight down) to reset the trolley latch into the run position. Hit the wall button or remote once — the trolley will travel along the rail and automatically re-couple to the chain carriage. Test one full cycle before you walk away.
