Universal Compatibility

This wireless keypad replaces original units for Chamberlain, LiftMaster, Sears and Craftsman openers manufactured since 1993 that use a purple, red, orange, yellow or green learn button. It is not compatible with Security+ 3.0 white-button models or dip-switch systems.

Learn Button Verification

The single specification that determines fit is the colour of the learn button on the motor unit; only purple, red, orange, yellow or green buttons are supported. White-button openers produced in 2026 and older dip-switch models will not pair with this keypad.

Sustained Outdoor Use

A flip-up cover shields the backlit keys from rain, snow and sun while the pre-installed 9V alkaline battery powers the unit without wiring. Rolling-code security generates a fresh access code every cycle, preventing code-grabbing during repeated daily operation.

Purple, red, orange, yellow and green learn buttons on Chamberlain, LiftMaster, Sears and Craftsman openers made since 1993 are compatible; white Security+ 3.0 buttons and dip-switch units are not.

Mounting screws are supplied in the box along with a pre-installed 9 V alkaline battery and step-by-step instructions for a no-wiring installation.
