Garage door opens/closes by neighbor

Last year, I got a brand new garage door and it kept opening up my neighbor's garage door as well. It turned out that we had the exact same type of garage doors that were happening to work on the same frequency. Lucky for you, though, it's not terribly too tough to change the frequency and make it so that both of your doors aren't opening and closing at the same time. All you have to do is get someone to reprogram the door or find a way to do it yourself. All American Garage Door

try changing frequencys you might have a neighbor close by that is using same frequency as you causing your door to open when they open theirs

Do you use the same garage door with your neighbor?

Make sure your neighbor doesn't have a remote with a sticking switch. Often times a person will stick an extra remote in a drawer and then place something on it that holds the button down. Try programming your remotes this way just in case you didn't.

Press and hold the button down on the remote while you press and immediately release the smart/learn button. Sometimes it can help if you are in the garage when you program your remotes this way and it will drown out any distant signal.

Have your neighbor bring over his remote and open or close your door with it. Then hold the smart/learn button in for 6 seconds on your opener. Then see if he can open your door. He shouldn't be able to because that procedure erases the memory in your opener. No remotes should work. You need to get that remote #53778 back and program it and then see if your neighbor can open your door. If he can open your door at any point after you have held that button in for 6 seconds you need to get a new door opener.

When the main light flashes 10 times and the door reverses it is a door sensor problem. Make sure they are pointed at one another and that the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor or wiring.

Shorten the antenna wire to reduce the distance it will pick up signal and/or fill the memory with new remote codes from a new and different remote.

I think your neighbor has a problem. Not you.

You say you "setup the remote and the main box but doesn't solve." I think you mean you programmed the unit but I'm not sure. Anyway try holding the smart/learn button in for 10 seconds and this will erase the memory. None of the remotes should work. Now when you are sure the neighbor will not be using their opener, program your remotes. This may be what you did but I'm not sure.

Have you seen the neighbor open your door? The reason I ask is because it is almost impossible. The most common cause of a door opening by itself is a bad wall control or the wiring leading to it. You can temporarily eliminate both possibilities by removing the wire from terminal 1 at the rear of the motor unit. Do this and ask your neighbor to bring over his remote and try it on your opener.
