If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.
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 steps
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 section.
When programming a garage door, it is advised
to park outside of the garage. Be sure that people
and objects are clear of the garage door or
gate operator 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 signal.

Programming the Universal Home
Remote System
Follow these steps to program up to three
devices:
1. Press and hold down the two outside Universal
Home Remote buttons, releasing only when
the Universal Home Remote indicator light
begins to flash, after 20 seconds. Do not hold
down the buttons for longer than 30 seconds
and do not repeat this step to program a
second and/or third hand-held transmitter to
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.
3. At the same time, press and hold both the
desired Universal Home Remote button and
the hand-held transmitter button. Do not
release the buttons until Step 4 has been
completed.
Some entry gates and garage door openers
may require you to substitute Step 3 with
the procedure noted in "Gate Operator and
Canadian Programming" later in this section.
