Troubleshooting a Garage Door Remote
Battery
A dead or dying battery is one of the most common and simplest reasons why a garage door remote is not functioning properly. Remove the battery, which is usually a lithium battery or other flat, round type, and bring it to the local hardware or home store to match up a new one.
Interference
Radio signals, Wi-Fi and other signals bouncing around can interfere with the garage door remote. Sometimes new systems added to the home, such as an electronic sprinkler setup or new outdoor lights, have enough power to interfere with the garage door remote. Shutting off all power in the house except for one circuit to which you attach the garage door can isolate an interference problem. If interference is coming from an outside force, such as a neighbor's Wi-Fi or a nearby military base, a new, more powerful remote may be in order.
Antenna
Locate the antenna on the garage door opener and make sure it is hooked up properly. You can make it longer by hooking wire to the end of it to extend its reach. Loop one end of the wire around the end of the antenna and let the other end reach out or coil it around.
Circuit Board
Sometimes the remote's circuit board goes bad, or it could simply be too dirty to function properly. Open the remote and use canned air to blast any dirt and dust from the board's crevices. Also make sure the battery terminals are lined up and touch the board when you depress the button. You can contact the remote's manufacturer and request a new circuit board.
Other
The manufacturer's help center may also be able to assist with problems common to that particular brand. Find the help center's phone number on your product packaging or manual. You can also call the store where you purchased the remote to see if they have the manufacturer's phone number.
