The older model 139.18775 now utilizes the GD-R31 compatible wireless keypad, which is designed to work with openers that have GREEN learn buttons for programming the keypad code. This keypad allows you to open or close your garage door without the need for a remote control or key. You can program a private 4-digit code directly into the unit to operate the door.
The package includes mounting screws, a battery, and programming instructions.
Orders are shipped on the next business day, and we offer a 30-day return policy for added convenience.
Locate the GREEN Learn button on your garage door opener power head (it will be a square GREEN button on the end of the motor unit where the antenna wire is located.) You may have to remove the light lens cover on some models.
