It doesn't take much effort to reset a Craftsman garage door opener or its keypad. Just take care to allow sufficient time between steps after adding a new personal identification code to the keypad, so the system can keep up with you. If the keypad is installed outside the garage, you'll need a helper or two during the reprogramming steps.
New Craftsman garage door openers perform much the same as other openers when you need to reset the keypad or the master control unit. Locate the Learn or Smart button, depending on the model you have, on the opener's motorized unit attached to the garage's ceiling. You'll need a stepladder to safely access it.
Reset the Keypad
The Smart or Learn button on the motorized unit attached to the garage ceiling resets the keypad and the control unit that operate the garage door opener's motor. You'll need to enter a new code into the keypad to make it operational again and reprogram the control unit. The remotes in your car should work after resetting them by pressing and holding the Enter button, releasing it when the indicator lights on the motor attached to the garage ceiling begin to blink.
To reset the keypad, position a stepladder near the motorized unit attached to the ceiling. Climb to the appropriate rung of the ladder -- without standing on the top step, which puts you at risk of tumbling off -- to reach the button. Press and hold the button until its indicator light goes out. Depending on the model you have, this can take from six to 30 seconds. Once the light goes out, the keypad is ready for you to reprogram.
New Wireless Keypads
To verify that the reset took, enter the old PIN code into the keypad to see if it opens the garage door. If it does, the reset didn't take. Repeat the step to reset the keypad and verify the old code doesn't work before proceeding.
Press and release the Learn or Smart button on the motor. Once the indicator light comes on, it should stay on for 30 seconds.
Enter your new four-digit PIN onto the keypad while the indicator light remains lit on the garage door opener's motor. You have a 30-second window to complete this while the indicator light remains lit on the motor. Depress and hold the Enter button on the keypad.
Release the Enter button once you observe the lights on the motor blinking. The blinking lights indicate the unit has learned and accepted the new code.
Test the new PIN code on the keypad to verify it operates the door. Reset the motor and reprogram the keypad if necessary until it works.
Already Installed Wireless Keypads
Locate the master control unit near the door connecting the house to the garage. This unit allows you to open the garage door from inside the closed garage. Once you reset the motor, you'll need two helpers to reprogram the keypad using the master control unit near the door that enters the garage unless the first helper can also see the indicator lights on the motor when operating the master control unit. An assistant needs to be able to see the lights to know if the programming took.
Enter a new four-digit PIN into the keypad in its mounted location outside the garage after resetting the motorized until that opens the garage door. After entering the new PIN, press and hold the Enter button on the keypad.
Instruct your helper to press and hold the Light button on the master control while you still hold the Enter button on the keypad.
Tell your helper to depress the Control button -- the one that opens the garage door -- and hold it while still holding the Light button on the master control while you still hold the Enter button the keypad. Three buttons should be pressed and held during this process.
Release all three buttons when advised that the indicator lights on the motor have started to blink.
To reprogram older systems, simply access the DIP switches inside the keypad, the remotes, the door control button mounted on the wall and the motorized unit. Change their settings so that they all match to the DIP-switch settings you choose for the motor that opens the garage door. These DIP switches toggle between On and Off positions. Most units have between five and 10 DIP switches to set. Never leave these set to factory settings; consider an upgrade to wireless systems for better security.
