Programming the HomeLink 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.
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. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand
-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly
(this may take up to 90 seconds).

2-58
If you have trouble programming HomeLink,
make sure that you have followed the directions exactly
as described and that the battery in the hand
-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
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
a 'Rolling Code' Featureº next in this section or contact
the manufacturer of HomeLink at 1
-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand
-held transmitter in
case you need to erase and reprogram HomeLink.
Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see ªProgramming the
HomeLink Transmitterº listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the ªLearnº or ªSmartº 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 Learn or Smart button,
refer to your garage door opener owner's manual
or contact the manufacturer of HomeLink at
1
-800-355-3515, or on the internet at
www.homelink.com. Because of the steps involved,
it may be helpful to have another person assist in
programming the transmitter.
2. Press the Learn or Smart 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 HomeLink in your vehicle and firmly
press and release the programmed HomeLink button
three times.

problems training the garage door opener, contact the
manufacturer of HomeLink at 1
-800-355-3515, or on
the internet at www.homelink.com.
