I need to change the code in my garage door opener.

It is a Craftsman 1/2 HP Chain Drive with two tramsmitters. I have lost my manual and need to know how to change the code. Please help ASAP!

You did not indicate the model of the opener.

There have been at least 3 different types of code systems that have been used over the years.

Chamberlain makes Chamverlain, Liftmaster, and Sears openers. They all use similar parts and proceedures.,1064,uid-jmdpbWViZ2trZg==_652,00.html

Look at #6, #11, and #12
