Quickly test the quality of your opener s wiring by following these steps.
Garage door won t open from outside with remote.
If the remote works from inside the garage but not from the outside then most likely the antenna wire on the garage door opener itself may be damaged broken or not in visible range.
I have replaced the battery on reprogrammed the remotes with no luck.
Try installing a new battery and attempt to open the door again with the remote.
Check the battery in your remote operator by walking into the garage holding it in your hand.
Check to be sure the antenna is attached and if it is not hanging down from the unit move the antenna so it can catch the beam being sent by the remote.
You can also try pushing the garage door button on the wall.
My garage door remotes will not open door from the outside unless you are right in front of the door.
Press the button as you observe a small blinking red light on the box where the chain enters and exits.
If that doesn t work and you still have a nonworking remote you may want to have a professional examine it.
