How to Open a Garage Door Manually in a Power Outage
Pull the red release cord, lift the door by its handles and reconnect the opener when power returns. This guide gives the steps, the checks to make first and the signs that mean you should not lift the door at all. Opening a garage door when the power is out comes down to one part: the manual release cord.
Four steps in the right order
Check first when not to lift
No outside access what the key kit does

How do you open a garage door by hand?
Pull the red emergency cord that hangs from the opener trolley, then lift the door by its handles. Do this only if the door feels normal. If it is very heavy, crooked, or will not stay up, a spring or cable may be broken and lifting it can be dangerous. Call a technician instead.
That is the whole idea. The rest of this page covers the order of the steps, what to check first, and how to reconnect the door to the opener afterwards.
What to check before you pull the cord
Chamberlain says not to operate the door manually if it feels extremely heavy, falls quickly when released, will not stay open, or if the springs, cables or rollers look damaged. A weak or broken spring can let the door drop fast.
The weight is the reason. One industry guide puts a single-car steel door at roughly 85 to 130 pounds and a two-car steel door at roughly 160 to 225 pounds, with wood doors heavier. On a healthy door the springs carry almost all of that. If a spring has failed, you are lifting it yourself.
Look at the door before you touch anything. A door that is crooked in the tracks, a frayed or slack cable, or a loud bang before the outage are all reasons to stop. The safety guide covers the warning signs in more detail. Part names such as the trolley and drum are explained in the garage door parts glossary.
Step by step: manual release and lift
- Find the red cord. It hangs from the trolley on the opener rail, usually with a red handle.
- Pull it down. On a square-rail opener Chamberlain says the arm disconnects and moves to vertical. On a T-rail opener it says to pull the cord straight down and then back toward the opener, so the trolley does not reconnect on its own.
- Lift by the handles. DASMA says to use the handles and never to put fingers between the door sections. Raise the door slowly and see that it stays up.
- Reconnect when power is back. Chamberlain says to pull the cord toward the opener, then run the opener fully open and fully closed. The trolley reconnects during that cycle.
Genie and LiftMaster use the same kind of red cord, but their support pages were not readable when this guide was written. If your opener is a different brand or looks different, check the manual for that model.
Can you open the door from outside the garage?
Only if the opener has a keyed emergency release fitted near the top panel. Chamberlain says that kit only disconnects the opener. It does not lift the door. Once it is released you still have to raise the door by hand, with the same checks as above.
If there is no keyed release and no other way in, call a technician. Prying at a door or the frame can bend the tracks and turn a power problem into a repair job.
Minnesota outages and battery backup
Connexus Energy, a Minnesota electric cooperative, tells members to test the garage door opener release before an outage, not during one. Try it once on a calm day so you know where the cord is and how it feels.
Outages can last. The Minnesota DNR says the December 2022 ice and snow storm left up to about 100,000 customers without power at some point, with ice up to a third of an inch in parts of the state. Ice on a garage door is a separate problem, covered in the winter care guide.
A battery backup opener keeps working when the power goes out. Chamberlain says its batteries typically last 1 to 2 years, and California has required backup on new residential openers since July 2019. If you are choosing an opener, see garage door openers.
Where a homeowner should stop
Fine to do yourself
- Pull the release cord
- Lift a door that moves easily
- Reconnect the trolley
- Test the release on a calm day
Leave to a technician
- A door that is heavy, crooked or will not stay up
- Springs and cables, which DASMA says need trained technicians
- Bottom brackets and anything under tension
- A trolley that will not reconnect
If the door will not stay up, see spring repair and cable repair. For a door that is stuck and needs help now, see emergency garage door repair. If the trolley will not reconnect or the opener stays dead once power returns, see opener repair.
Manual garage door release: common questions
Is it safe to lift a garage door by hand?
Only if the door is undamaged and moves easily. If it is very heavy, crooked or will not stay up, stop and call.
How do I reconnect the opener after pulling the cord?
Chamberlain says to pull the cord toward the opener, then run the opener all the way open and all the way closed. The trolley reconnects on that cycle.
Will the outside key release open the door?
No. Chamberlain says the exterior kit only disconnects the opener. You still lift the door by hand.
How long does a battery backup last?
Chamberlain says the battery typically lasts 1 to 2 years. How many open and close cycles you get in an outage depends on the model.
My door will not open even by hand. What now?
A broken spring, a snapped cable or a door off its track can all lock a door in place. See garage door won’t open or why a garage door is not working.
If you are unsure what you are looking at, call and describe it. Do not force a door that is heavy, crooked or stuck.
Call if the door will not open by hand
Describe what the door is doing, what happened before it stopped and what you have already tried.
What to have ready
- Your address and the nearest cross street
- Whether the door is up, down or stuck part way
- Whether the release cord was pulled
- Any bang, crooked panel or slack cable you saw
