forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards. If
you cannot program the transmitter after repeated

“Rolling Code” Feature (If Equipped)
If you have not previously programmed the hand

recognize HomeLink.

door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the Learn or Smart button,
refer to your garage door opener owner’s manual or
contact the manufacturer of HomeLink at
