Check the owners manual because they often have the codes in the booklet so you can change the pin. They are also sometimes on the remotes just in case you need to change the pin because you forgot it. I think you have to reset the whole device and the motor. KJ Garage Door Repair

The specifications that you need are the model number off the opener. Then check the yellow pages for a Liftmaster or Chamberlain dealer. They will help you in a heart beat.

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
For possible future reference:

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.
