Why is my garage door remote not working?

Common causes include:

• A flat or weak battery
• The remote has lost its programming
• The remote is damaged
• The remote is not compatible with the opener
• A faulty garage door receiver
• Signal interference
• A problem with the garage door opener

Try replacing the battery first. If the remote still does not operate the door, check whether the remote needs to be reprogrammed or whether there is a problem with the opener or receiver.
