66LM LiftMaster Chamberlain Sears Craftsman Garage Door Opener Keyless Entry Coding Instructions

WIRELESS KEYLESS ENTRY – MODEL SERIES 740 AND 66

FEATURES OF THE KEYPAD TRANSMITTER

Personalized Code: Up to 10,000 possible combinations. Codes can easily be changes if desired.

Operation: Opener activates when 4-code digits and ENTER button are pressed.

The Keypad Transmitter will open and close the door even if the Door control Lock Switch feature is ON.

If wrong numbers are accidentally pressed, correction can be made immediately. The Enter key will transmit only the last four digits.

The keypad will blink for 15 seconds after the code is transmitted. During that time you can STOP or REVERSE door travel just by pressing the ENTER key.

The keypad transmitter can be used with garage door opener receivers having a yellow, gray, white or green “learn” button.

Setting the Code:

1.       Press and release the “learn” button on motor unit.  This can be found where you see the antenna wire hanging from the motor head (you may have to take the lens cover off). If antenna wire is not hanging from motor head then you have an external receiver which is a black box approx. 6" x 2" mounted somewhere in the garage with a antenna wire hanging from it (pop off cover to find Learn Code Button). The learn indicator light will glow steadily for 30 seconds.

2.       Within 30 seconds, enter a four-digit personal identification number (PIN) of your choice on the keypad. Then press and hold the ENTER button.

3.       Release the button when the motor unit lights blink. It has learned the code. If light bulbs are not installed, two clicks will be heard.
