Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
2-42

Keep the original transmitter for use in other vehicles as
well as for future HomeLink®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the buttons
for longer than 30 seconds and do not repeat this
step to program a second and/or third transmitter to
the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
HomeLink
®buttons while keeping the indicator light
in view.3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
2-43

6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.” Do not
repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle) your
hand-held transmitter until the frequency signal has been
successfully accepted by HomeLink
®. The indicator light
will ash slowly at rst and then rapidly. Proceed with
Step 4 under “Programming HomeLink
®” to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
2-44

Erasing HomeLink®Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
®is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under “Programming HomeLink
®.”
Individual buttons can not be erased, but they can be
reprogrammed. See “Reprogramming a Single
HomeLink
®Button” next.
Reprogramming a Single HomeLink®
Button
To program a device to HomeLink®using a HomeLink®
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
®button. Do
not release the button.
2. The indicator light will begin to ash after
20 seconds. While still holding the HomeLink
®
button, proceed with Step 2 under “Programming
HomeLink®.”
Resetting Defaults
To reset HomeLink®to default settings do the following:
1. Hold down the two outside buttons for about
20 seconds until the indicator light begins to ash.
2. Continue to hold both buttons until the HomeLink
®
indicator light turns off.
3. Release both buttons.
