Review on 📱 LiftMaster 877max: Sleek Light Gray Remote Control for Efficient Access Control by John Espindola

Recently replaced my old garage door keypad with a LiftMaster 877 Max (aka device). Got it a day early from Revain and installed it in about 1 hour - including moving cars, stairs, installation etc. Please note my setup was designed to run two single garage doors. Here are some installation tips that may be helpful: The device comes with an installed 9V battery and is ready to use. The device can be fully programmed from the comfort of your kitchen table (or any other location of your choice). You don't have to assemble it first and then stand in the cold/wind and press buttons while reading the instructions. The programming instructions were precise and to the point. I can't find any errors. After you've programmed the device (i.e. entered the opening codes to use), take the device up the stairs and press the learn button on the garage door opener. Follow the printed instructions and you've completed the tricky and possibly tricky part. To confirm the operation, enter the code on the pad, press enter, and hopefully the garage door will work. Now place the block on the outside wall of the garage. Test if it still works. Ready! Hope that helps.
