Universal Wireless Keypad Entry
The Craftsman CMXZDCG440 wireless keypad provides keyless garage access for homeowners using Chamberlain, LiftMaster or Sears Craftsman openers with yellow, purple, red, orange or green learn buttons manufactured since 1993. It supports rolling-code security that changes the access code after every use. This unit is not compatible with Security+ 3.0 white-button openers produced in 2026 or legacy dip-switch models.
Simple Wall-Mount Installation
The battery-powered keypad mounts on any wall surface without wiring, using the included screws and pre-installed 9V cell. A flip-up cover shields the backlit buttons from rain, snow and harsh sunlight while maintaining visibility in darkness. It frees the user from carrying a remote or physical key and allows temporary PINs for service workers without revealing the master code. Openers such as the Craftsman 200.57933, 57943, 57953, Series 100, CR1150, 139.57943 and 139.57953 cannot be paired with this keypad.
Sustained Outdoor Reliability
Rolling-code technology generates a fresh code on every activation, preventing code-grabbing during repeated daily cycles. The weather-resistant cover and backlit keypad maintain consistent operation through temperature swings and precipitation. Users who require compatibility with Security+ 3.0 white learn buttons or dip-switch systems will need a different solution, as this keypad does not support those protocols.

Questions about this item
How long does the pre-installed 9V battery last under daily use before it needs replacing?
The keypad ships with a 9V battery already installed; typical life is several months of regular operation before a fresh cell is required.
Does the flip-up cover and backlit keypad add noticeable heat or noise during continuous outdoor exposure?
No, the unit is passive — it draws power only when a button is pressed, so it generates no audible noise or measurable heat in any weather.
Which specific garage-door opener models must I already own for this CMXZDCG440 keypad to pair successfully?
It works with Chamberlain, LiftMaster and Craftsman openers that have a yellow, purple, red, orange or green learn button manufactured since 1993; it will not pair with Security+ 3.0 white-button units, dip-switch models, or Craftsman series 200.57933, 57943, 57953, 100, CR1150, 139.57943 or 139.57953.
