Press and release the appropriate button on the
HomeLink transmitter. The indicator light comes on
while the signal is being transmitted.

If the hand

-

held transmitter appears to program the

HomeLink transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a “rolling
code” system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.

To determine if you have this system, press the button
on the HomeLink transmitter that you have programmed
already. If the indicator light on the HomeLink
transmitter flashes rapidly for two seconds and then
turns solid, the garage door opener has a rolling code
system. In a rolling code system, the garage door motor
head unit must be trained to the HomeLink transmitter.

If you have not previously programmed the hand

-

held

transmitter to the HomeLink transmitter, see
“Programming the HomeLink transmitter” listed
previously. If you have completed this programming
already, you now need to train the garage door opener
motor head unit to recognize the HomeLink transmitter.
Refer to your garage door opener owner’s manual for
the proper transmitter training procedure for your garage
door opener brand.

1. Find the training button on the garage door opener

motor head unit. The exact location and color of the
button may vary by garage door opener brand. If you
have difficulty finding the training button, refer to
your garage door opener owner’s manual.

Because of the steps involved, it may be helpful 
to have another person assist in programming 
the transmitter.

2. Press the training button on the garage door opener

motor head unit.

Following this step, you have 30 seconds to 
start Step 3.
