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!
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.

when you are programming , how long do you push LEARN button for, If you push for 6 or more seconds, you are wiping out all code, Push for 1 second to add a remote or keypad,

SOURCE: Liftmaster Keypad problem
First thing to do is make sure it has a good battery installed. If this doesn't take care of the problem then the keypad is going bad and needs to be replaced. It is important that you get the same keypad as there are others out there that look the same but will not work.
