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.

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.

Look at the LED light next to the
SMART/LEARN button on rear of the motor unit. You may need to remove
a light lens cover in order to see it. If the light is flashing
rapidly this means you have a stuck button on one of your remote
controls. Take the batteries out of each remote control. When you
remove the batteries from the bad remote, the light will stop
flashing. This remote needs to be replaced.
If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.
