How To Use the Garage Door Emergency Release

You're rushing out the door, late for work, and you hit the button to open your garage door. But instead of the familiar whirring sound, there's silence. The automatic opener has malfunctioned, and the door is stuck firmly shut. Now what? In this situation, you'd be thankful for a little-known feature most garage doors have: the garage door emergency release cord.

A garage door emergency release is a pull cord that allows you to disengage or reengage the garage door opener in an emergency, such as a power outage or a malfunctioning garage door opener. We’ll cover how to use your emergency release cord and ensure it always works properly.



Step One - Locate the Emergency Release Cord

Before you take any steps, ensure your garage door is closed. Never pull the emergency release cord when the door is open. This could cause the door to slam shut, potentially damaging the door or causing injury.

Now that you’ve ensured your safety, it's time to find the hero of this situation: the emergency release cord. It's typically a red rope hanging from the garage door opener track near the ceiling. It might be within reach, but if not, you'll need a sturdy stepladder to access it safely.

Step Two - Pull the Emergency Release Cord

Once you’ve located your emergency release cord, gently pull the cord downward. You should hear a click as a mechanism inside the opener disengages. This disconnects the trolley (the part attached to the door) from the opener itself.

Once you hear the click, you'll be able to manually lift the garage door without the motor assisting or resisting.

Step Three - Manually Open the Garage Door

With the click confirming the disconnect, you can manually lift the garage door. Since the motor is no longer assisting, expect the door to feel heavier than usual.

Grip the handle firmly near the bottom center of the door and gradually lift it — you may need someone to assist you with larger or heavier doors. As you lift, the door will glide along the tracks. You'll likely need to use both hands and exert some force, especially at the beginning.

Once the door is at the desired height, hold it steady or prop it open with a secure brace (like a 2x4) to prevent it from slamming shut.

Step Four - Reengage the Trolley

With the garage door held open (either manually or with a brace), locate the trolley (the part attached to the door that usually runs along the track). Carefully guide the trolley back up the track until the latch clicks back into place. Do not release the door until you hear this confirmation click.

Once secure, you can slowly lower the garage door and test the opener by using the remote control. If the door moves smoothly and the opener functions normally, then the reengagement was successful. If not, consult a qualified service professional for further assistance.

Remember, this is for emergencies only — call a professional to fix the opener for regular use.

How To Test Your Garage Door Emergency Release

It's wise to test your garage door emergency release cord periodically to ensure it functions properly.

  1. Safety first: Make sure your garage door is clear of obstructions and completely closed. Never test the release cord with the door open.
  2. Power down: Turn off the power to your garage door opener at the breaker box.
  3. Locate the emergency cord: Find the red emergency release cord hanging from the garage door opener track near the ceiling.
  4. Lift the door: Pull the emergency release cord and lift the garage door part of the way. Note whether or not it stays in place. If it rises or falls, you could have an unbalanced door or a damaged spring or cable. This is a safety issue that needs the immediate attention of a garage door professional. Do not proceed with next steps unless the door stays in place.
  5. Close the door: Manually close the door and reconnect the power to your door and opener.
  6. Reconnect the trolley: Pull the cord toward the door until you hear a clicking sound.
  7. Test your opener: Make sure your garage door works as it once did by using the remote or switch to open and close it.

If you pull the cord and don't hear a click or the door remains difficult to lift, it's best to call a garage door service professional to diagnose and repair the emergency release mechanism.

Common Issues With the Garage Door Emergency Release

While a faulty emergency release cord is less common, other garage door problems can mimic its malfunction. If you pull the cord and the door remains stubbornly shut, the culprit could be elsewhere.

  • Garage door becomes misaligned: Tracks can bend or rollers can come loose, making the door difficult to lift even with the emergency release disengaged.
  • Garage door won’t open all the way: Worn-out springs or a broken cable can limit the door's travel, making it seem like the release cord isn't working.
  • Garage door motor isn’t working: Even if the emergency release is functional, a dead motor won't allow you to open the door electronically.
  • Garage door cables are worn: Frayed or snapped cables can prevent the door from lifting properly, regardless of the emergency release.

Garage Door Emergency Release FAQ

Precision Garage Door Service is your trusted expert in garage door safety and operation. With years of experience and a deep understanding of garage door systems, we're here to provide clear and helpful answers to your questions about emergency releases and other garage door concerns.

How do I reset my garage door after pulling the red cord?

Once you've used the red cord and your garage door is open, reconnect it by lifting the door manually. Find the latch on the trolley and align it with the opener track. Push the trolley back until it clicks into place. Now your garage door should function normally with the remote control.

What happens if you pull the emergency release on a garage door?

Pulling the emergency release cord on a closed garage door disengages it from the opener motor. This allows you to lift the door manually, typically using a lot more force than usual. Never pull the red cord while the door is open — it’ll cause the door to slam shut.

How do you unlock a garage door in an emergency?

If your garage door opener malfunctions and you're locked out, gently pull the emergency release cord to disconnect the door from the motor. Then, lift the door and secure it open with a brace.

How do I get my garage door to engage again?

Once you've used the emergency release and your garage door is open, lift the door until the trolley is near the opener track. Look for a latch mechanism on the trolley, then carefully guide it back into place on the opener track. You'll hear a click when it's reengaged; then you can lower the door and test the opener with your remote.
