I bought the Liftmaster 387 LM to replace my slightly cheaper but intermittently operable Skylink S89 universal remote keypads. (“Intermittently” is the key word – I don’t want to go out for a walk, and return to find myself locked out!) The Liftmaster keypad, though a few dollars more expensive, appears to be much better made. My GDOs are both 12-DIP switch circa 1995 Genie Promax PMX75 openers. Reading through the reviews, there seemed to be some confusion whether the 387 LM would work in this application. I was happy to find that it works beautifully with these older Genie units. And where it takes needle nose pliers to remove jumper plugs, and a tiny screwdriver to set the frequency for the Skylink remote, I was able to program the 387 LM effortlessly, sitting in the car, by entering the command sequence from the keypad. The old Skylink remote keypad also worked initially but began to fail – particularly as the weather got colder. Hopefully my new Liftmaster 387 LM keypad will be found faithful – and reliable!
Differences (Liftmaster vs Skylink)
--------------------------------------------
Battery: 9-volt vs. 2-CR2032’s
Configure with: keypad vs. DIP switch, slide switch, jumper, and keypad!
PIN entry: Terminate PIN with ‘0’ vs. ‘#’
PIN entry feedback: none vs. audible beep
Another positive difference with the Liftmaster 387 is that the keypad remains active (and illuminated) for a little over 10 seconds after the door begins to move. During that time, any key can be pressed to reverse door travel – similar to the original Genie keypad behavior.
