To program another device such as an additional garage door opener, a security device, or home lighting, repeat Steps 1 through 8, choosing a different function button in Step 7 than what you used for the garage door opener.

Programming Universal Home Remote - Rolling Code Rolling code garage door openers are used for garage doors produced after 1996 and are code protected. Rolling code means the coded signal is changed every time your remote control garage door opener is used. Programming a rolling code garage door opener involves time-sensitive actions, so read the entire procedure before you begin. If you do not follow these actions, the device will time out and you will have to repeat the procedure. 2. Go to the garage. Locate the garage door motor head and press and release the "learn" button. After pressing the "learn" button, you have 10 to 30 seconds to complete Step 4 depending on your garage control unit. If you cannot locate the "learn" button, refer to the owner's guide for your garage door opener. 144
