Operating the HomeLink Transmitter

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.

“Rolling Code” Programming (If Equipped)

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.

2. Press the training button on the garage door opener

motor head unit.

Please note that following this step, you have

30 seconds to start Step 3.
