Where's the smart button on Sears garage door opener....trying to locate the smart/ learn button on my Sears 1/3 hp garage door opener so I can program it to the universal remote in my new car

It sounds like your logic board has gone bad. It is what receives the signal from the remote and actuates the door. If it is bad no remote will work.

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!

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.

The only procedure I have ever followed is to press the learn button and then enter the code, and not do anything else. I think your last step of holding the button until the light goes out is clearing codes as fast as you enter them. Just stop after you enter your code and let the learn mode time out on its own. That should do it.

And don't put your head through the wall. It just causes more headaches.

If both remotes quit at or about the same time then it is most likely the receiver that has quit. Especially if you have had electrical storms in the area. The receiver is part of your logic board.

Testimonial: "Thank you. So does that mean I have to replace my receiver?"

The button to program the unit is near where all those white wires go.
