What Does the Lock Button on a Garage Door Opener Actually Do?
The lock button on a garage door opener disables remote and keypad signals while keeping the wall control active. It’s meant to prevent the door from being opened wirelessly — useful during vacations, nighttime hours, or when extra security is needed.
That said, the feature is often triggered without anyone realizing it. A family member might press it, thinking it controls the light, or a child might hit the button while playing near the wall panel. From there, remotes stop working — and it feels like the opener has failed. Thankfully, it’s an easy fix.
