821LMC-S LiftMaster Smart Garage Control

Smartphone control: Control, secure and monitor your garage door from anywhere.

Works with most brands of garage door openers manufactured after 1993 that use photoelectric sensors that do not shut off. It is not intended for use with openers in which the photoelectric sensors located near the bottom of the garage door change power mode (e.g., lights on the sensors turn off after the door is closed), or any Chamberlain Group opener with a yellow learn button manufactured between 2010 and 2021, or any Linear opener.

New design: Compact modern design with a white finish that blends in with ceilings, walls and garage doors. New mounting plate simplifies install.

Improved setup: Bluetooth Low Energy (BLE) integration makes setup easier than ever. Download the myQ® App and follow the in-app instructions to get set up in minutes.

Works with Amazon Key: Enables convenient and secure In-Garage Delivery.
