Programming the Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold
down the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
surface of the HomeLink Transmitter so that you
can still see the indicator light.

3. Using both hands, press the hand-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the red
light on the HomeLink Transmitter flash rapidly.
The rapid flashing indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.
If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand
-held transmitter is not dead. If you still cannot
program it, turn the hand
-held transmitter end over end
and try again. The HomeLink Transmitter 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 attempts, refer to
ªTraining a Garage Door Opener with Rolling Codesº
later in this section or contact the manufacturer of the
unit at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.Canadian Owners: During programming,
the hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.
Operating the Transmitter
Press and hold 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 ªrolling
codeº 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 flashes rapidly for one or two seconds,
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.

Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the
hand
-held transmitter to the HomeLink Transmitter,
see ªProgramming the Transmitterº 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 will
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 available to assist you in
programming the transmitter.
2. Press the training button on the garage door opener
motor head unit. An indicator light will begin to flash
when the motor head unit enters the training mode.
Following this step, you have 30 seconds to start Step 3.3. Return to the HomeLink Transmitter in your
vehicle and firmly press and release the HomeLink
Transmitter button you have already programmed for
two or three seconds. Press and release the button
again (you may need to do this step up to three times)
to make sure that the HomeLink Transmitter has been
trained to the garage door opener motor head unit.
Check that the training was successful. The motor
head unit indicator light should no longer be flashing.
The garage door opener should now recognize the
HomeLink Transmitter. You may either use the
HomeLink Transmitter or the hand
-held transmitter
to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, call the
manufacturer of the unit at 1
-800-355-3515.
Erasing Channels
To erase all three programmed channels, hold down the
two outside buttons until the indicator light begins to
flash (after 20 seconds). Release both buttons.
Accessories
Accessories for the HomeLink Transmitter are available
from the manufacturer of the unit. If you would like
additional information, please call 1
