Universal Remote System
Programming
If the vehicle has this feature, you
will see these buttons with one LED
indicator next to them in the
overhead console. 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 Remote
system 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 Remote system. Because
of the steps involved, it may be
helpful to have another person
available to assist with programming
the Universal Remote system.

Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal
Remote system programming. It is
also recommended that upon the
sale of the vehicle, the programmed
Universal Remote system buttons
be erased for security purposes.
See“Erasing Universal Remote
System 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 being
programmed.
It is recommended that a new
battery be installed in the hand-held
transmitter for quicker and more
accurate transmission of the
radio-frequency signal.Programming the Universal
Remote System
For questions or help programming
the Universal 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. Hold the end of the hand-held transmitter about 3 to 8 cm
(1 to 3 in) away from the
Universal Remote system
buttons while keeping the
indicator light in view. The
hand-held transmitter was
supplied by the manufacturer of
the garage door opener receiver
(motor-head unit). 2. At the same time, press and
hold both the hand-held
transmitter button and one of the
three Universal Remote system
buttons to be used to operate
the garage door. Do not release
the Universal Remote system
button or the hand-held
transmitter button until the
indicator light changes from a
slowly to a rapidly flashing light.
You now may release both
buttons.
Some entry gates and garage
door openers may require
substitution of Step 2 with the
procedure noted in “Gate
Operator and Canadian
Programming” later in this
section.

3. Press and hold for five secondsthe newly trained Universal
Remote system button (the
button selected in Step 2) while
observing the indicator light and
garage door activation.
.If the indicator light stays on
continuously or the garage
door starts to move when
the Universal Remote
system button is pressed
and released, then the
programming is complete.
There is no need to
continue programming
Steps 4 through 6.
.If the Universal Remote
system indicator light blinks
rapidly for two seconds,
then turns to a constant
light and the garage door
does not move, continue
with programming Steps 4
through 6. It may be helpful to have
another person assist with
the remaining Steps 4
through 6.
“Learn”
or“Smart” Button
4. After Steps 1 through 3 have been completed, locate the
“Learn” or“Smart” button inside
the garage on the garage door
opener receiver (motor-head
unit). The name and color of the
button may vary by
manufacturer.
5. Firmly press and release the “Learn” or“Smart” button. After
pressing this button, you will
have 30 seconds to complete
Step 6. 6. Immediately return to the
vehicle. Firmly press and hold
for two seconds the Universal
Remote system button, selected
in Step 2 to control the garage
door, and then release it. If the
garage door does not move or
the lamp on the garage door
opener receiver (motor-head
unit) does not flash, press and
hold the same button a second
time for two seconds, and then
release it. Again, if the door
does not move or the garage
door lamp does not flash, press
and hold the same button a third
time for two seconds, and then
release.
The Universal Remote system
should now activate the
garage door.
To program the remaining two
Universal Remote system buttons,
begin with Step 1 of “Programming
the Universal Remote System.”

Gate Operator and Canadian
Programming
If you have questions or need help
programming the Universal 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 the Universal Remote
system 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 the
Universal Remote System”
procedures, regardless of where
you live, replace Step 2 under
“Programming the Universal Remote
System” with the following:
Continue to press and hold the
Universal Remote system 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 Remote system. The
Universal Remote system indicator
light will flash slowly at first and then
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System” to complete.
Universal Remote System
Operation
Using the Universal Remote
System
Press and hold the appropriate
Universal Remote system button for
at least half of a second. The
indicator light will come on while the
signal is being transmitted.
Erasing Universal Remote
System Buttons
All programmed buttons should be
erased when the vehicle is sold or
the lease ends.
To erase all programmed buttons on
the Universal Remote system
device:
1. Press and hold down the two
outside buttons until the
indicator light begins to flash.
This should take about
10 seconds.
2. Release both buttons.
