I taped the safety sensors together, facing each other, and placed them on top of the motor on the side with the new door. Hate those damn things. I installed the opener back in '03 when we moved in. Tried and tried to defeat those sensors, but that company sure doesn't want you to do that.
I have to hit the button in the truck, then walk out the closing door ... otherwise I have to dig through my pile of keys to lock the 2 locks on the side door. In the summer, the door and jambs swell, making that task a pain in the ass. Much easier to just lock the door from inside, then escape while the door is closing. Stupid sensors wouldn't let me do that. Apparently lawyers have had their way with garage door opener manufacturers ...
The other door's opener is a 30+ year old Alistair unit. Chain driven & indestructible. Not a safety device to be found on that one.
