  1. Works great - watch out for potential program issue 5 Star Review

    Posted by on May 24th 2018

    Received my 877 Max and was eager to program and install it. I had another that was already in use on another door. I had some problem getting the keypad and the MyQ controller to work together. I tried everything I could find in the LIftmaster instructions, the 877 instructions and emailed Open Door Discount Remotes who provided me that customer service number at Liftmaster. A representative from Liftmaster talked me through several troubleshooting attempts and appeared about ready to have me send the keypad in as faulty when she asked if I used a 0 as one of the numbers in my code. I had. Apparently hitting 0 during programming terminates the programming command. So, each time I tried to enter the code I had selected it stopped programming. Within about 30 seconds after choosing a different entry code the keypad was working perfectly.

  2. Works perfectly, trivial to install 5 Star Review

    Bought this to replace a "universal" third-party keypad remote that failed after a year. This one is much better-constructed than the old one, even though it the price was about the same. This one is trivial to program and very easy to mount on the house trim, and is far more reliable than the old one. Open Door's free shipping was prompt and the package arrived in perfect condition. Highly ecommended if you have a compatible opener.

  3. EXCELLENT 5 Star Review
