Manually opening and closing the garage door got old, so I bought a new Chamberlain LiftMaster 3265 model on ebay from SpringkingUSA. It’s a 1/2 HP, chain drive motor attached to a one-piece 8″ t-rail. It came with two 3-key remotes, multi-control panel, and a combo-key pad. The primary feature folks should be looking for is the rolling code technology.
For my first install, it went smoother than I thought – it took me about 4 hours. I credit YouTube for the preliminary installation tips, and the best factory instructions I’ve encountered in a long time. I recommend reviewing several tips on garage door security at ITS Tactical, too.
