Press and hold for 3 seconds the button on the wall control that has an icon of a lock. The light should quit blinking and your remotes will once again work. Holding that button for 3 seconds toggles your openers vacation mode.

If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

Remote not working


you will need to train (link) the remote to the garage door opener. to do this you will need to find the remote "train" button on the operator.
If you have the manual for the garge door opener this will show you where it is located.
push the train button on the operator, an LED light will start blinking. Then push one of the buttons on the remote. the LED light on the operator will stay on. push the button on the remote again and the light on the operator will turn off.
try the remote it should work now.

Garage door remote won't open the garage door


The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.

Remotes don't work (3)


Did you inadvertantly hit the "vacation lock" button on the Mounted push button? This will cause the remotes not to work. Try hitting the button again, and then see if the blinking goes to solid green.

Good Luck
