The LiftMaster MAX 2-button keychain remote is compatible with Chamberlain®, LiftMaster®, and most Craftsman® garage door openers made after 1997 with safety sensors. It can control up to two garage doors or gates and offers a range of up to 1,300 feet under ideal conditions. The compact keychain design makes it easy to carry, while secure encrypted communication helps protect access. For compatible openers with a yellow or white learn button, the remote can also be set up and managed through the myQ app.
