SOURCE: Sears Craftsman Garage Door Opener Wireless Keypad Model and a LiftMaster Chamberlain Professional Garage Door

Hello,

I had the same frustrating dilemma with my Craftsman LiftMaster garage door and Keypad, Model 139.53754-01 (dated 10/06; and has the # 315 MHz).

To resolve “the dilemma”, grab your keypad, climb up on a ladder to access the garage door opener’s motor unit. On the right side of the motor unit, remove the white plastic casing by pressing buttons on each side and pulling down. This will expose the programming area, and for our purposes, the “Learn” button.

1. On the motor unit, press and release the “Learn” 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 ENTER button when the motor unit lights blink. The code has been “learned”/stored/activated.

Good Luck, and I Hope this Helps!
Gail

How to change an existing, known PIN
(Changing an existing PIN can be done with the wireless remote keypad, and does not require access of the motor unit.)

From the keypad:

1. Enter the four digits of the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.

2. Enter your new 4-digit PIN and press Enter. The motor unit lights will blink once when the PIN has been “learned”/stored/activated. Test by entering the new PIN, and pressing Enter.

Okay...upon further inspection, my left spring has broken in two. Going to call around for some quotes to replace the spring. Thanks for the suggestions.

SOURCE: Garage door will not open properly

You might have a broken spring. Check on the a the header above the door there should be a tube with a drum on each end and 2 springs (maybe one) towards the center. If one of the springs has a gap (1-2 inches) in it. If it does you will need to call a door company in your area. I recommend you replace both springs. If you need to get you cars out some times you can help the operator to lift the door by lifting the door while the operator is lifting the door. Be very careful not to get your fingers in a pinch point and be sure to lower the door the same way.

To program the keypad, first unplug the garage door opener from the electrical outlet. Next remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next enter your desired four-digit PIN number into the keypad. Slide the switch back to operate and plug the garage door opener back in. The keypad should be programmed.

SOURCE: Liftmaster wireless keypad closes but won't open the door

If you are sure the battery is good you have a bad keypad. The signal strength is so weak it will not penetrate the door.

Craftsman motor and Liftmaster Remote Control


Some will work and some wont. If you go to this website it will tell you.
You must have the model number off the motor unit of your opener. It is on the end closest to the door and starts with 139.

Go to this website and find your model number in the left column. The second column is the model number of the Liftmaster remote that works.
