    This happened to me when I loose power. I contacted Sears and they said I had to push a red button on the back of the garage door opener (Machine) and hold it for 3 seconds and then walk over to the keypad within 60 seconds and enter a 4 digit code followed by the enter button. The garage should open

YOU MAY NEED TO REPLACE THE BATTERY IN THE KEYPAD.

FIND THE SQUARE BUTTON NEXT TO WHERE THE WIRES CONNECT TO THE CIRCUIT BOARD. PRESS AND RELEASE THE SQUARE BUTTON - YOU NOW HAVE 20 SECONDS TO ENTER THE NEW CODE AND PRESS ENTER.

HOPE THIS HELPS

I have a chamberlain/craftsman garage door keypad from previous home owner and do not know the old password to reset my own. How do I reset the password without knowing the old one?


Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

No code for keypad


It depends on the type of operator and keyless you have. If they are are compatable, the battery is good in the keyless and there are no wires to the keyless:
1. Push (don't hold) the Smart button (on the back or right side of the operator looking from the back of the operator toward the garage door)
2. Within 40 seconds type in 4 digit code on keyless, push and hold enter 3 seconds

Dvd password accidentally entered How do I reset?


I just had the same problem tonight. My wife figured it out. The system password is 'BOSE', which is 2673 from the telephone keypad. Enter 2673 and this will unlock the default system password. My old 321 system also lost it's FM presets, so I think the original CMOS battery died on it's motherboard.

Lost manual, can't remember the password


The factory default password is ?8-8-8-8?. If you reset to the factory defaults this should work.
