Craftsman is a line of home tools and appliances owned by Sears Holdings Corp., the same company that owns and operates Sears department stores. You might want to change the code on your Craftsman garage door keypad if you suspect someone may have found out your code. It is also good practice to periodically change your garage entry code to ensure your home and belongings are secure. Allow roughly five minutes for this task.
Enter your four-digit PIN code on the keypad outside your garage.
Press and hold the "#" button. The opener light will blink twice.
Release the "#" key. Enter your new four-digit code.
Press "Enter." The opener light will blink once. The new code is ready to use.
