The Genie website and Genie-Help.com both offer instructions for programming Genie Intellicode and other remotes. Manuals are available on both the Genie and The Home Depot's websites for Intellicode two- and three-button remotes as well as Genie keypads.
The standard instructions for most Genie garage door opener products are simple and straightforward. Locate the Learn Code button on the garage door unit, and press and release. This instructs the opening unit to broadcast the code for the remote control to pick up.
Press and release the remote control button to program. Ensure that the LED is either flashing or glowing steadily. Pressing the button again stops the process and stores the code. Test by pressing the button and ensuring that the garage door opens.
