Press and hold for 3 seconds the lock button on the wall control. The light should stop blinking and your remotes should now work.

on the back of your garage door opener there is a colored learn button--press and release-the learn indicator light will glow for a short time usually 30 seconds. within thirty seconds press and hold the buton on the hand held remote that you wish to operate your garage door. release the button when the motor unit lights blink. if you don;t have a light, two clicks will be heard. it has learned the code. procedure will be different for multi function control.

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.
