How to Open a Garage Door Manually When the Power Is Out
Updated November 2026 · Part of our emergency guides
When the power goes out, a garage door opener stops working, but the door itself does not have to stay stuck. Every opener has a manual release that lets you move the door by hand. The catch is that using it the wrong way can drop the door or hurt someone, so the order of the steps matters.

How to Open a Garage Door Manually: Step by Step
- Confirm the door is fully closed. If it is open or partly open, do not pull the cord. The door can drop.
- Unplug the opener or switch it off at the outlet if you can reach it safely.
- Find the red cord hanging from the trolley on the opener rail.
- Pull the cord straight down once. That disconnects the door from the opener.
- Lift the door slowly with a helper, keeping your hands and fingers away from the panel joints.
- Stop if it is heavy, drops or jams. Do not force it.
What to Do in Different Situations
| Situation | What to do |
|---|---|
| The door is closed and the car is inside | Follow the steps above, then prop the door open only if it stays up on its own |
| The door is open and the power goes out | Leave the cord alone, and keep clear. The door can be left open until power returns |
| The door is partly open | Do not pull the cord. Keep clear and call for help |
| The door feels very heavy after releasing it | A spring has probably broken. Stop and see our spring repair page |
| The door is off its track or crooked | Do not move it. See our off-track repair page |
How Do You Reconnect the Opener Afterward?
Wait until the power is back and the door moves smoothly by hand. Then follow your opener’s manual to reconnect the trolley, which usually means running the door until the carriage re-engages. Test the sensors and auto-reverse before you rely on it again.
How Can You Avoid Getting Stuck Next Time?
- Make sure everyone in the house knows where the red cord is
- Practice the release once with the door closed and a helper
- Consider a battery backup opener, which keeps working through an outage. See our opener installation page
- Keep a flashlight near the garage entry
- Have the springs checked before hurricane season. Our hurricane guide explains the checklist
How the Release Cord Works
The red cord pulls on a latch on the trolley, the carriage that rides the opener rail. That latch is what connects the door to the chain or belt. Pulling the cord separates the two, so the door is no longer held by the opener and can be moved by hand. That is also why the door can drop if you pull the cord when it is open: a door that is out of balance or has a weak spring was relying on the opener to hold it.
What If the Door Will Not Move After You Release It?
- Check that the door’s own lock bar is not engaged, since many doors have a manual lock
- A jammed trolley or carriage can keep the door connected
- A broken spring makes the door too heavy to lift. See our spring repair page
- A bent track or a door off its track will bind. See our off-track page
- A snapped cable leaves one side hanging
If none of those is the cause and the door still will not move, stop and call rather than forcing it.
Different Openers, Different Releases
| Opener type | How the release works |
|---|---|
| Chain or belt drive on a ceiling rail | A red cord on the trolley, as described above |
| Wall-mount (jackshaft) | Often a different release, such as a lever or chain. Check the manual |
| Battery backup models | The same release, plus the battery runs the opener when power fails |
If you are not sure which type you have, look at your opener’s manual or call. Do not experiment with the door open.

Frequently Asked Questions
Can I open my garage door without power?
Yes, if the door was working normally before the power went out and you did not hear a bang. Pull the red release cord when the door is fully closed, then lift the door slowly with a helper. If it feels very heavy, stop and call.
Is it safe to pull the red cord?
Only when the door is fully closed. If the door is open or partly open, it can drop when released.
Why is my garage door so heavy to lift by hand?
A properly balanced door is easy to lift. If it is very heavy, a spring has probably broken or the door is out of balance, and it needs repair.
Will a battery backup opener work in a power outage?
Yes, for a limited number of cycles, depending on the model.
