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 flash, after 20 seconds. This step will
erase the factory settings or all previously
programmed buttons.
2-48
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.
