If your garage door opener remote is starting to act up, you may need to change the battery. Most overhead garage door remotes use a standard 9-volt battery, but it’s always best to check your specific model for the correct type of battery.
To change the battery in your garage door remote, start by removing the cover from the back of the remote. This will expose the batteries. Next, remove the old batteries and insert new ones in their place. Be sure to match up the positive and negative ends of the batteries before snapping them into place. Once the new batteries are in, replace the cover on the back of the remote and test it out. If it still isn’t working properly, you may need to replace other parts of your garage door opener system.
