people and objects near the
garage door.
Make sure the hand-held
transmitter has a new battery
for quick and accurate
transmission of the
radio-frequency signal.
Programming the
Universal Remote System
Programming involves
time-sensitive actions and may
time out, requiring the
procedure to be repeated.
Read these instructions
completely before
programming the Universal
Remote system. It may help to
have another person assist
with the programming
process.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
with the indicator light in
view. The hand-held transmitter was supplied
by the manufacturer of the
garage door opener
receiver.
2. Press and release one of the three Universal
Remote system buttons to
be programmed. Press and
hold the hand-held
transmitter button. Do not
release the hand-held
transmitter button until
the indicator light changes
from a slow to a rapid flash
or continuous light. Then
release the hand-held
transmitter button.
Some garage door
openers may require
substitution of Step 2 with
the procedure under
“Radio Signals for Some
Gate Operators” later in
this section.
3. Press and hold the newly programmed Universal
Remote system button for
five seconds while watching the indicator light
and garage door
activation.
.If the indicator light
stays on continuously or
the garage door moves
when the button is
pressed, then
programming is
complete. There is no
need to complete
Steps 4–6.
.If the indicator light does
not come on or the
garage door does not
move, a second button
press may be required.
For a second time, press
and hold the newly
programmed button for
five seconds. If the
indicator light stays on
continuously or the
garage door moves
when the button is
pressed, then
programming is
complete. There is no
need to complete
Steps 4–6.

.If the garage door does
not move, continue with
programming Steps 4–6.
Learn or Smart Button
4. After completing Steps 1– 3, locate the Learn or
Smart button inside
garage on the garage door
opener receiver. The name
and color of the button
may vary by manufacturer.
5. Press and release the Learn or Smart button.
Step 6 must be completed
within 30 seconds of
pressing this button.
6. Return to the vehicle and firmly press and hold the
trained Universal Remote
system button for two seconds and release.
Repeat the
“press/hold/
release” sequence up to
three times to complete
the training process.
The Universal Remote system
should now activate the
garage door. Repeat the
process for programming the
remaining two buttons.
For questions or programming
help, see www.homelink.com/
gm or call 1-800-355-3515.
For calls placed outside the
U.S., Canada, or Puerto Rico,
international rates will apply
and may differ based on
landline or mobile phone.
Radio Signals for Some
Gate Operators
Some gate operators and
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.
If the programming did not
work, replace Step 2 under
“Programming the Universal
Remote System”
with the
following:
Press and hold the Universal
Remote system button while
pressing and releasing the
hand-held transmitter button
every two seconds until the
signal has been successfully
accepted by the Universal
Remote system. The Universal
Remote system indicator light
will flash slowly at first and
then change to a rapid flash or
continuous solid-light. Proceed
with Step 3 under
“Programming the Universal
Remote System” to complete.
