your thread can can reminded me of my question. The house I live at has a gate outside. Well to get in you have to press an access code on the keypad. Its very hard to get to this keypad when i'm in my truck because its so tall. Inside the gate on the wall hidden there is this doorbell. when you press it, the gates open. Theres only 2 wires running to it. Would this mean that if i just contacted those 2 wires together it would open the gate? And ifso can I get some sort of wireless remote to accomplish this?
