How do I change my code on my key pad. model 1140 chamberlain opener



There are currently 2 manuals online for the keypads. The first is for the 740cb and is located at http://www.chamberlain-diy.com/doityourself/pages/productmodeldetail.aspx?modelId=1474

The second is for the 940d which is located at http://www.chamberlain-diy.com/doityourself/pages/productmodeldetail.aspx?modelId=1473

Either one should give instructions for programming your keypad.
