How To Change Code On Old Craftsman Garage Door Opener
Changing the code on an old Craftsman garage door opener depends on the model you have. Older models typically have dip switches or a Learn button to reset the code. Follow the steps below based on your model.

If your Craftsman garage door opener is from the 1990s or earlier, it likely uses dip switches to set the code.
