How to open an automatic garage door during a power outage?

22.07.2025

Automatic garage doors, controlled by a remote or even via a smartphone app, are undoubtedly excellent solutions that have revolutionized the market. They allow for quick and easy opening and closing without the need to leave your car. Unfortunately, problems can arise during a power outage. At such times, operating the garage door may seem complicated, especially for those who are used to the convenience of modern technology. After all, automatic opening systems are designed to save time and effort, but when power is suddenly lost, they can cause inconvenience. So what should you do if you’re returning home during a storm and your garage door refuses to cooperate? Or when a power cut leaves your car trapped in the garage?

In moments like these, it is essential to know the proper steps to safely and effectively open the garage door manually. Understanding how the unlocking mechanism works and being familiar with emergency procedures helps reduce stress and avoids potential damage. Below, we explain how the emergency release mechanism in automatic garage doors functions, which tools may be useful in a crisis, and how to prepare for such situations in the future. We will also advise how to act without compromising safety or damaging the door. With these guidelines, power outages will no longer be a source of concern, and your automatic garage door will become an even more reliable element of your home.

Why is it important to know emergency garage door opening procedures?

A power outage can occur at any time, often at the worst possible moment. Imagine being late for an important meeting, only to realize your garage door won’t open. Such issues can also happen during severe storms when damaged power lines lead to long-lasting blackouts. Not being able to open your garage door quickly becomes not just frustrating but also a real limitation during emergencies.

Knowing how to manually open your garage door is not just a matter of convenience, but also of safety. Without proper knowledge, attempts at manual operation can easily damage the drive system, cables, or hinges, leading to expensive repairs.

Additionally, emergency procedures protect users from potential risks. While garage door mechanisms are designed to meet high safety standards, improper use during a power outage can lead to sudden falling of the door or jamming of components.

Finally, awareness of emergency systems also helps protect property. Garage doors often act as an additional layer of security against burglary. Improper handling during a power cut could weaken this protection. Many emergency procedures involve coded locks or keys inaccessible to outsiders, ensuring security even in difficult circumstances.

Standard emergency release mechanisms in automatic garage doors

Manufacturers of automatic garage doors anticipate the risk of blackouts and design systems with built-in emergency release mechanisms. These allow safe and quick manual control when power is unavailable. Their effectiveness depends both on their engineering quality and the user’s familiarity with them.

The most common types of emergency release mechanisms are:

  1. Manual release cable

This is the simplest and most common method, usually accessible from inside the garage. A cable connected to the motor can be pulled to disengage the automatic drive. Once released, the door can be freely operated manually. It is reliable and rarely fails, but the drawback is that it can only be accessed from inside. If your garage has no other entrance, an external lock system may be necessary.

  1. Emergency lock with key

Mounted on the exterior of the garage door, this lock allows access to the manual release system from outside using a dedicated key. After unlocking, the user can pull the release cable and operate the door manually. This solution is particularly useful when the garage has no separate entry. However, it must be protected from weather conditions and the key should be stored in an easily reachable but safe place.

Step by step: how to manually open a garage door from the inside

If a power outage occurs, you can open the garage door from the inside using the built-in manual release system. Here are the steps you should follow:

  1. Locate the release cable

This cable is usually found near the garage door motor. It typically has a handle or loop for easy grip. If you are unfamiliar, check your garage door manual beforehand.

  1. Detach the motor

Firmly but carefully pull the release cable. This disconnects the motor, switching the system into manual mode. Be sure to avoid rough movements to prevent damage.

  1. Manually lift the door

Once disengaged, lift the garage door smoothly with both hands placed safely on the panel. If the springs don’t balance the weight properly, ask someone to assist.

Emergency procedure for opening a garage door from the outside

If internal access is not possible, the external lock system comes into play. Here’s how to use it:

  1. Locate the emergency lock

It is usually installed at a convenient height on the garage door, sometimes covered with a protective cap.

  1. Insert the key

Use the dedicated key to unlock it as instructed by the manufacturer. Typically, only a gentle turn is needed.

  1. Disengage drive and lift the door

Unlocking the emergency lock grants access to the release cable. Pull it, switch to manual mode, and lift the door smoothly.

Most common mistakes when manually opening garage doors (and how to avoid them)

Manually opening the door during an emergency can be stressful, which sometimes leads to serious mistakes. Here are the main ones:

  • Using excessive force

Overexertion can damage cables, springs, or panels. Always act calmly and steadily, and if necessary, call a technician instead of forcing the mechanism.

  • Ignoring safety measures

Improper lifting may lead to injuries or cause the door to drop suddenly. Always lift with both hands and keep distance from moving parts.

  • Not knowing where release mechanisms are

Wasting time searching for the emergency release or not having the key adds stress. Familiarize yourself with the door system in advance and keep the key outside the garage but in a secure location.

  • Poor maintenance

Failure to maintain cables, springs, and locks may cause them to jam during emergencies. Regularly service and lubricate all moving parts.
