all of the sudden my garage door opener remote is opening and closing my next-door neighbors garage door. we have both tried to reset and reprogram our remotes and still the same problem. the inside of my remote does not allow for any security code changes and does not have any dip switches ( i think it has the rollover code technology). his remote does have these dip switches, but changing them does not seem to help. anyone have any idea how to resolve this problem? thanks.
