Original Liftmaster 60LM keypad
Sears 139.18164
The 66LM is for older openers with 9 small DIP switches inside the receiver. If your opener has a colored "learn" button, you need the 377LM (purple) or 976LM (green/orange/red) instead.
Programming the 66LM
Match the keypad's 9-switch DIP block to the receiver, then set your 4-digit PIN.
- Open the back of the 66LM. Set its 9-switch DIP block to match the receiver inside your opener.
- Replace the cover. Press and hold * and # together until the LED blinks, then enter your new 4-digit PIN twice. The LED glow confirms.
- Test: enter the PIN and press ENTER. The opener should activate within 100 feet.
For privacy, pick a unique 9-switch pattern that doesn't match your neighbors'. Avoid all-up or all-down patterns.

Set the DIPs once and it just works. Backlight is bright, gasket is solid in our New England weather.
