Will the gate swing open if unlocked with a key -- say, even w/o a wireless transmitter?
I would like to get the gate opener with remote transmitters (i.e., without the keypad), but I am worried about what will happen if UPS has a package for us, or if the yard maintenance guys come by to mow when we aren't home, etc.
Thanks!1 answer-
