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.
The HomeLink Transmitter is disabled when the valet
lock switch inside the glove box is activated. For more
information, see “Valet Lock” in the Index.
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.
Following this step, you have 30 seconds to
start Step 3.
