HomeLink® channels.
HomeLink® Buttons

NOTE:
HomeLink® is disabled when the Vehicle Secu -
rity Alarm is active. NOTE:

Only use this transceiver with a garage door
opener that has a “stop and reverse” feature as
required by federal safety standards. This includes
most garage door opener models manufactured
after 1982. Do not use a garage door opener
without these safety features. Call toll-free

for safety information or assistance.

BEFORE YOU BEGIN PROGRAMMING
H
OMELINK®
Be sure that your vehicle is parked outside of
the garage before you begin programming.
For more efficient programming and accurate
transmission of the Radio Frequency (RF) signal
it is recommended that a new battery be placed
in the hand-held transmitter of the device that is
being programmed to the HomeLink® system.
WARNING!
Do not attempt to stow the bed step with your
hands. The low clearance space between the
bed step and the rear bumper as the bed step
returns to the stowed position could result in
injury to your hands or fingers.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people, pets or other objects
are in the path of the door or gate. Only use
this transceiver with a garage door opener
that has a “stop and reverse” feature as
required by Federal safety standards. This
includes most garage door opener models
manufactured after 1982. Do not use a
garage door opener without these safety
features.
Vehicle exhaust contains carbon monoxide,
a dangerous gas. Do not run your vehicle in
the garage while programming the trans -
ceiver. Exhaust gas can cause serious
injury or death.

CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission.
Canadian radio frequency laws require
transmitter signals to time-out (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink® to pick up
the signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner.
It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

2. Place the hand-held transmitter 1 to
3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program
while keeping the HomeLink® indicator
light in view.
3. Continue to press and hold the HomeLink® button, while you press and release (cycle)
your hand-held transmitter every two seconds until HomeLink® has successfully
accepted the frequency signal. The
indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds
or longer in rare cases. The garage door
may open and close while you are
programming.
5. Press and hold the programmed HomeLink® button and observe the
indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the Home -
Link® button is pressed.
To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.
If you unplugged the garage door opener/
device for programming, plug it back in at this
time. Reprogramming A Single HomeLink® Button
(Canadian/Gate Operator)
To reprogram a channel that has been
previously trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Press and hold the desired HomeLink®
button until the indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button, proceed with “Canadian/Gate Operator Programming”
step 2 and follow all remaining steps.
USING HOMELINK®
To operate, push and release the programmed
HomeLink® button. Activation will now occur for
the programmed device (i.e. garage door
opener, gate operator, security system, entry
door lock, home/office lighting, etc.) The
hand-held transmitter of the device may also be
used at any time.

SECURITY
It is advised to erase all channels before you sell
or turn in your vehicle.
To do this, push and hold the two outside
buttons for 20 seconds until the orange
indicator flashes. Note that all channels will be
erased. Individual channels cannot be erased.
The HomeLink® Universal Transceiver is
disabled when the Vehicle Security Alarm is
active.
TROUBLESHOOTING TIPS
If you are having trouble programming
HomeLink®, here are some of the most
common solutions:
Replace the battery in the garage door
opener hand-held transmitter.
Push the LEARN button on the garage door
opener to complete the training for a Rolling
Code.
