Hi, Brian, I’m having the exact same problem. My partner & I are getting started in the Fix & Flipp industry, we bought a place and yes, it has one of the older discontinued Sear Door Openers. I’m still searching for a remote, I’m heading to Lowe’s now to price a universal Liftmaster brand. Craftsman took over Sears then had a name change to Liftmaster far as their garage door and gate openers as well as some appliance replacement parts. Wish me luck will drop you a line if it works. If you find out something before I do will appreciate the heads up .
