Neighbors Remote Opens My Garage Door
my neighbor's opener opens my garage door.
Clear all codes on your opener.
If yours uses rolling code technology (Has a "learn" button) press and hold the learn button for 30 seconds. Then program your remote while your neighbor is not home.
Press and release the "learn" button, then within 30 seconds, press and release the button on your remote. You will have to do the same for each remote and wireless keypad.
If your opener is older and uses "dip-switch" technology, you will find a row of tiny switches on your overhead operator and under the cover of your remote.
Change the position of a couple of these switches on the opener and set the switches of your remote to the same identical position.
