Universal Home Remote
System Operation
(With One Triangular LED)
If there is one triangular Light Emitting Diode (LED)
indicator light above the Universal Home Remote
buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems,
and home automation devices.
Do not use the Universal Home Remote 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.Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming
the Universal Home Remote.
Keep the original hand-held transmitter for use in other
vehicles as well as for future Universal Home Remote
programming. It is also recommended that upon the sale
of the vehicle, the programmed Universal Home Remote
buttons should be erased for security purposes. See
“Erasing Universal Home Remote Buttons” later in this
section.
When programming a garage door, park outside of the
garage. Park directly in line with and facing the garage
door opener motor-head or gate motor-head. Be sure that
people and objects are clear of the garage door or gate
that is being programmed.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.

Programming the Universal Home
Remote System
For questions or help programming the Universal
Home Remote System, call 1-800-355-3515 or go to
www.homelink.com.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before starting. Otherwise, the device will time out and
the procedure will have to be repeated.
To program up to three devices:
1. From inside the vehicle, press and hold down the
two outside buttons at the same time, releasing
only when the Universal Home Remote indicator
light begins to ash, after 20 seconds. This step will
erase the factory settings or all previously
programmed buttons.Do not hold down the buttons for longer than
30 seconds and do not repeat this step to program
the remaining two Universal Home Remote
buttons.
2. Hold the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the Universal
Home Remote buttons while keeping the indicator
light in view. The hand-held transmitter was supplied
by the manufacturer of your garage door opener
receiver (motor head unit).
3. At the same time, press and hold both the Universal
Home Remote button to be used to control the
garage door and the hand-held transmitter button.
Do not release the Universal Home Remote
button or the hand-held transmitter button until
Step 4 has been completed.
Some entry gates and garage door openers may
require substitution of Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
2-48

4. The indicator light on the Universal Home Remote
will ash slowly at rst and then rapidly after
Universal Home Remote successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained Universal Home
Remote button and observe the indicator light.
If the indicator light stays on continuously,
the programming is complete and the garage door
should move when the Universal Home Remote
button is pressed and released. There is no need to
continue programming Steps 6 through 8.
If the Universal Home Remote indicator light blinks
rapidly for two seconds and then turns to a
constant light, continue with the programming
Steps 6 through 8.
It may be helpful to have another person assist with
the remaining steps.6. After Steps 1 through 5 have been completed,
locate inside the garage the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. The name and color of the button
may vary by manufacturer.
7. Firmly press and release the “Learn” or “Smart”
button. After you press this button, you will have
30 seconds to complete Step 8.
2-49

8. Immediately return to the vehicle. Firmly press and
hold the Universal Home Remote button, chosen in
Step 3 to control the garage door, for two seconds,
and then release it. If the garage door does not
move, press and hold the same button a second time
for two seconds, and then release it. Again, if the
door does not move, press and hold the same button
a third time for two seconds, and then release.
The Universal Home Remote should now activate
the garage door.
To program the remaining two Universal Home Remote
buttons, begin with Step 2 of “Programming the
Universal Home Remote System.” Do not repeat Step 1,
as this will erase all previous programming from the
Universal Home Remote buttons.
Gate Operator and Canadian
Programming
If you have questions or need help programming the
Universal Home Remote System, call 1-800-355-3515 or
go to www.homelink.com.
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds of
transmission. This may not be long enough for Universal
Home Remote 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 or garage door opener by
using the “Programming Universal Home Remote”
procedures, regardless of where you live, replace
Step 3 under “Programming Universal Home Remote”
with the following:
Continue to press and hold the Universal Home Remote
button while you press and release every two seconds
(cycle) the hand-held transmitter button until the
frequency signal has been successfully accepted by the
Universal Home Remote. The Universal Home Remote
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming Universal
Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home Remote
button for at least half of a second. The indicator light
will come on while the signal is being transmitted.
